[0051] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0052] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically separate entities. That is, these functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0053] The flowcharts shown in the accompanying drawings are for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, while others may be combined or partially combined. Therefore, the actual execution order may vary depending on the actual situation.

[0054] It should also be noted that the term "plurality" used in this application refers to two or more. "And / or" describes the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0055] In the related art, in order to meet the needs of different users for text font size, a text font size adjustment function is deployed in the application. However, in the related art, the application includes different business modules, and each business module is provided with a text setting program. When implementing the text font size adjustment, it is necessary to first notify the business module, and then the business module queries the internal call relationship, finds the text setting program set by itself according to the internal call relationship, and then adjusts the font size of the text based on the text setting program. The implementation logic is complex, and the internal call relationships of different business modules are different, which is not convenient for maintenance. Based on this, the embodiment of the present application proposes a text font size adjustment method and device, electronic device, and storage medium, so that the text font size adjustment implementation logic is simple and easy to maintain.

[0056] See also Figure 1 , Figure 1 Schematic diagram of an implementation environment involved in the present application, which includes a terminal device 100 and a text font size adjustment device 200, wherein the terminal device 100 and the adjustment device 200 communicate with each other via a wired or wireless network.

[0057] The terminal device 100 has an application installed therein, wherein the application provides a font size adjustment function. The adjustment apparatus 200 is used to adjust the text font size of the application installed in the terminal device 100 .

[0058] Among them, after receiving the font size adjustment instruction, the adjustment device 200 determines the text to be adjusted whose font size is to be adjusted from the application of the terminal device 100; searches for the target program entry corresponding to the business module to which the text to be adjusted belongs from the program entry set, wherein the program entry set includes program entries corresponding to multiple business modules deployed by the application, and the program entry is used to provide a direct channel to access the text setting program set in the corresponding business module; determines the target font size of the text to be adjusted according to the font size adjustment instruction; passes the target font size of the text to be adjusted into the corresponding text setting program according to the target program entry, so that the corresponding text setting program adjusts the font size of the text to be adjusted contained in the corresponding business module based on the target font size of the text to be adjusted; in this way, through the program entry set, the direct channel of the text setting program set in each business module deployed in the application can be queried, and the target font size of the text to be adjusted can be passed into the corresponding text setting program through the direct channel, without the need to perceive the calling relationship of the text setting program within each business module, so that the implementation logic is simple and easy to maintain.

[0059] Among them, the terminal device 100 includes but is not limited to mobile phones, computers, intelligent voice interaction devices, smart home appliances, car terminals, etc.

[0060] In one embodiment, the adjustment device 200 can be a server of the terminal device 100, wherein the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms. This is not restricted here.

[0061] In another embodiment, the adjustment device 200 and the terminal device 100 may be the same electronic device. That is, after receiving the font size adjustment instruction, the adjustment device 200 determines the text to be adjusted whose font size is to be adjusted from the application programs installed on the device; searches for the target program entry corresponding to the business module to which the text to be adjusted belongs from the program entry set; determines the target font size of the text to be adjusted based on the font size adjustment instruction; and transmits the target font size of the text to be adjusted to the corresponding text setting program based on the target font size of the text to be adjusted, so that the corresponding text setting program adjusts the font size of the text to be adjusted contained in the corresponding business module based on the target font size of the text to be adjusted.

[0062] It should be noted that, in addition to the aforementioned application scenarios, the embodiments of the present application can also be applied to various application scenarios, including but not limited to cloud technology, artificial intelligence, smart transportation, assisted driving, etc. In actual applications, corresponding adjustments can be made according to the specific application scenarios. For example, if applied to a cloud technology scenario, the application in the terminal device 100 can be an application running based on cloud technology; if applied to an artificial intelligence scenario, the application in the terminal device 100 can be an application created based on artificial intelligence technology; if applied to a smart transportation or assisted driving scenario, the terminal device 100 can be an in-vehicle terminal, a navigation terminal, etc., and the application in the terminal device 100 can be an application for navigation, an application for assisted driving, etc.

[0063] See also Figure 2 , Figure 2 This is a flow chart of a method for adjusting the font size of a text according to an exemplary embodiment. Figure 1 The implementation environment shown and Figure 1 The text font size adjustment device 200 in the illustrated implementation environment is specifically implemented.

[0064] like Figure 2 As shown, in an exemplary embodiment, the method for adjusting the text font size may include steps S110 to S140, which are described in detail as follows:

[0065] Step S110 : After receiving the font size adjustment instruction, determine the text to be adjusted whose font size is to be adjusted from the application program.

[0066] First, it should be noted that an application refers to a computer program designed to perform one or more specific tasks. During operation, an application displays a page that may contain text, images, etc. A font size adjustment instruction is used to instruct adjustment of the font size of the text contained in the application. It may indicate enlarging the font size of the text or reducing the font size of the text. The font size adjustment instruction may be generated based on a user's operation. That is, the user may trigger a font size adjustment function in the application to generate a font size adjustment instruction. For example, the application may include a font size adjustment control, and the user may trigger the font size adjustment control through a user input interface (e.g., a physical button or a touch screen), thereby generating a font size adjustment instruction. Alternatively, the font size adjustment instruction may be automatically generated based on relevant parameters. For example, in order to implement a function that adaptively adjusts the text font size based on the distance between the user and the terminal device, a font size adjustment instruction may be automatically generated when the distance between the user and the terminal device changes. Of course, the font size adjustment instruction may also be generated based on other methods, and this embodiment does not limit the method for generating the font size adjustment instruction.

[0067] The text to be adjusted is the text in the application whose font size needs to be adjusted. It can be Rich Text Format (RTF) or plain text. This embodiment does not limit the type of text to be adjusted. It should be noted that Rich Text supports a variety of formats, including text, links, pictures, etc., and supports adjustment of underline, font size, word spacing, baseline offset value, font paragraph style, line spacing, line wrapping method, and text alignment parameters.

[0068] Secondly, during the running process of the application, a font size adjustment instruction for the application may be received. After receiving the font size adjustment instruction, the text to be adjusted, whose font size is to be adjusted, may be determined from the application.

[0069] The specific method for determining the text to be adjusted whose font size is to be adjusted from the application can be flexibly set according to actual needs. For example, in one embodiment, in order to achieve comprehensive adjustment of the font size of text within the application, all text included in the application can be used as the text to be adjusted; or, in another embodiment, the text included in the page currently displayed in the application can be used as the text to be adjusted; or, in yet another embodiment, the page currently displayed in the application and the page currently stored in the cache can be first determined, and the text included in the determined page can be used as the text to be adjusted.

[0070] Step S120 , searching the program entry set for a target program entry corresponding to the business module to which the text to be adjusted belongs.

[0071] It should be noted that there are multiple business modules deployed in the application. For example, for "WeChat", it includes business modules such as "Friends Circle", "Official Account", and "Video Account". In each business module, a text setting program is provided. The text setting program is used to control parameters such as the font size of the text, for example, the setfont() function. The program entry set contains program entries corresponding to multiple business modules deployed by the application. The program entry is used to provide a direct channel to access the text setting program set in the corresponding business module. In this way, the text setting program set in the business module can be directly accessed through the direct channel, so there is no need to perceive the calling relationship of the text setting program within each business module.

[0072] After determining the text to be adjusted whose font size is to be adjusted from the application, determine the business module to which the text to be adjusted belongs, so that the program entry corresponding to the business module to which the text to be adjusted belongs can be found from the program entry set, and the found program entry is used as the target program entry.

[0073] Step S130 : determining the target font size of the text to be adjusted according to the font size adjustment instruction.

[0074] The target font size is the font size of the text to be adjusted after adjustment. In other words, the target font size is the font size that the text to be adjusted is expected to reach.

[0075] After receiving a font size adjustment instruction and determining the text to be adjusted whose font size is to be adjusted from the application, the target font size of the text to be adjusted can be determined based on the font size adjustment instruction. The method of determining the target font size of the text to be adjusted based on the font size adjustment instruction can be flexibly set according to actual needs. For example, the font size adjustment instruction can be parsed. If the font size adjustment instruction includes a target font size parameter for the text to be adjusted, the target font size of the text to be adjusted can be obtained from the font size adjustment instruction. If the font size adjustment instruction only includes a font size adjustment trend parameter, wherein the font size adjustment trend parameter includes enlarging the font size or reducing the font size, the target font size of the text to be adjusted can be determined based on the current font size of the text to be adjusted and the font size adjustment trend parameter.

[0076] It should be noted that Figure 2 In the embodiment, the example of executing step S120 first and then executing step S130 is used for explanation; in actual operation, step S130 may be executed first and then step S120, or step S120 and step S130 may be executed at the same time. In this embodiment, the execution order of step S120 and step S130 is not restricted.

[0077] Step S140 , the target font size of the text to be adjusted is passed to the corresponding text setting program according to the target program entry, so that the corresponding text setting program adjusts the font size of the text to be adjusted contained in the corresponding business module based on the target font size of the text to be adjusted.

[0078] After finding the target program entry and determining the target font size of the text to be adjusted, the calling relationship related to the text setting program in the business module can be skipped, and the target font size can be directly passed into the corresponding text setting program according to the target program entry, so that the corresponding text setting program adjusts the font size of the text to be adjusted contained in the corresponding business module based on the target font size. For example, assuming that the application includes three business modules, namely business module a, business module b, and business module c, and the text to be adjusted belongs to business module a, then the program entry corresponding to business module a is used as the target program entry, and the target font size is passed into the program entry corresponding to business module a, so that the text setting program set in business module a adjusts the font size of the text to be adjusted in business module a based on the target font size.

[0079] Among them, the specific way in which the text setting program adjusts the font size of the text to be adjusted contained in the corresponding business module based on the target font size of the text to be adjusted can be flexibly set according to actual needs. For example, the text setting program can control the generation of text data of the text to be adjusted corresponding to the target font size, and then, when the page to which the text to be adjusted belongs is displayed, the generated text data will be drawn in the page to which the text to be adjusted belongs.

[0080] The technical solution provided by this embodiment, after receiving the font size adjustment instruction, determines the text to be adjusted whose font size is to be adjusted from the application; searches for the target program entry corresponding to the business module to which the text to be adjusted belongs from the program entry set, wherein the program entry set includes program entries corresponding to multiple business modules deployed by the application, and the program entry is used to provide a direct channel to access the text setting program set in the corresponding business module; determines the target font size of the text to be adjusted according to the font size adjustment instruction; passes the target font size of the text to be adjusted into the corresponding text setting program according to the target program entry, so that the corresponding text setting program adjusts the font size of the text to be adjusted contained in the corresponding business module based on the target font size of the text to be adjusted; through the program entry set, the direct channel of the text setting program set in each business module deployed in the application can be queried, and the target font size of the text to be adjusted is passed into the corresponding text setting program through the direct channel, without the need to perceive the calling relationship of the text setting program within each business module, so that the implementation logic is simple, and the font size adjustment method of each business module is the same, which is convenient for maintenance and upgrading.

[0081] See also Figure 3 , Figure 3 FIG. 1 is a flow chart showing a method for adjusting the font size of a text according to another exemplary embodiment. Figure 3 As shown, under the condition that a text setting program is set in each business module included in the application, Figure 2 Before step S120 (searching the target program entry corresponding to the business module to which the text to be adjusted belongs from the program entry set) in the illustrated embodiment, the method may further include steps S210 to S230, which are described in detail as follows:

[0082] Step S210: Search for a text setting program in each business module.

[0083] The application program is deployed with multiple business modules, and each business module is provided with a text setting program. In this embodiment, the text setting program is searched for in each business module included in the application program.

[0084] Step S220: construct a direct channel for accessing the found text setting program, and generate a program entry corresponding to the corresponding business module according to the direct channel.

[0085] After finding the text setting program, a direct access channel is constructed to access the text setting program, and based on the direct access channel to the text setting program, a program entry corresponding to the business module to which the text setting program belongs is generated. For example, assuming that text setting program a belongs to business module A, after finding text setting program a in business module A, a direct access channel is constructed to access text setting program a, and based on the direct access channel to text setting program a, a program entry corresponding to business module A is generated.

[0086] The specific implementation method of constructing a direct channel for accessing the found text setting program can be flexibly set according to actual needs. For example, in one implementation, a direct channel for accessing the found text setting program can be constructed based on memory mapping technology.

[0087] Step S230: obtaining the program entry set based on the generated program entry.

[0088] After generating the program entry corresponding to each business module, a program entry set can be obtained.

[0089] In this embodiment, before adjusting the font size of the text, a text setting program is first searched for in each business module, a direct channel for accessing the found text setting program is constructed, and a program entry corresponding to the corresponding business module is generated based on the direct channel. Then, a program entry set is obtained based on the generated program entry, so that after receiving the font size adjustment instruction, the program entry of the font setting program corresponding to the text to be adjusted can be quickly found based on the program entry set, thereby adjusting the font size of the text to be adjusted, improving the speed of font size adjustment, and in the process of searching for the font setting program, there is no need to perceive the complex calling relationship within the business module, so the implementation logic is simple, which is convenient for subsequent maintenance and upgrades.

[0090] See also Figure 4 , Figure 4 yes Figure 3 The flowchart of step S220 in the embodiment shown is in an exemplary embodiment. Figure 4 As shown, the process of constructing a direct channel for accessing the found text setting program may include steps S221 to S222, which are described in detail as follows:

[0091] Step S221 : inserting an anchor point at the starting point of the found text setting program through a preset function to construct a mapping relationship between the preset function and the corresponding text setting program.

[0092] The preset function can be a hook function or other functions. In iOS (a mobile operating system developed by Apple), the hook function can be implemented through method swizzling. It should be understood that method swizzling is a syntax feature used in iOS development, which allows iOS programs to be hooked during operation.

[0093] By using a preset function, an anchor point is inserted at the starting point of the found text setting program, thereby establishing a mapping relationship between the preset function and the corresponding text setting program.

[0094] Step S222: generating a direct channel for accessing the corresponding text setting program according to the mapping relationship between the preset function and the corresponding text setting program.

[0095] After obtaining the mapping relationship between the preset function and the corresponding text setting program, a direct channel for accessing the corresponding text setting program can be generated based on the mapping relationship between the preset function and the corresponding text setting program, thereby obtaining the program entry corresponding to the corresponding business module. In this way, by calling the preset function, the anchor point of the text setting program can be found, and the text setting program set in the business module can be directly accessed based on the anchor point, thereby providing a unified entry for the text setting programs of multiple business modules in the application.

[0096] See also Figure 5 , Figure 5 FIG. 1 is a flow chart of a method for adjusting text font size according to another exemplary embodiment. Figure 5 As shown, in Figure 2 After step S130 (determining the target size of the text to be adjusted according to the font size adjustment instruction) in the illustrated embodiment, the method may further include steps S310 to S320, which are described in detail as follows:

[0097] Step S310 , determining a target size of the view to which the text to be adjusted belongs based on the target font size of the text to be adjusted, the view to which the text to be adjusted belongs, and the view layout relationship of the page to which the text to be adjusted belongs.

[0098] It should be noted that the view to which the text to be adjusted belongs is the parent view of the text to be adjusted, and the text to be adjusted will be displayed in this view.

[0099] If only the text size is adjusted, the text size may not match the view size, resulting in an uncoordinated screen and incomplete text display. To avoid these problems, in this embodiment, the size of the view to which the text to be adjusted belongs is also adjusted. After determining the target font size of the text to be adjusted, the target size of the view to which the text to be adjusted belongs can also be determined based on the target font size, the view to which the text to be adjusted belongs, and the view layout relationship of the page to which the text to be adjusted belongs.

[0100] The specific implementation of step S310 can be flexibly set according to actual needs.

[0101] For example, in one example, based on the target font size of the text to be adjusted, the view to which the text to be adjusted belongs, and the view layout relationship of the page to which the text to be adjusted belongs, the process of determining the target size of the view to which the text to be adjusted belongs may include steps S311 to S312, which are described in detail as follows:

[0102] Step S311 : obtaining a target size of a display area corresponding to the text to be adjusted based on a target font size of the text to be adjusted.

[0103] The specific method of obtaining the target size of the display area corresponding to the text to be adjusted based on the target font size of the text to be adjusted can be flexibly set according to actual needs.

[0104] For example, in one embodiment, step S311 may be steps S410 to S450, which are described in detail as follows:

[0105] Step S410: Obtain the specific content of the text to be adjusted.

[0106] Step S420: Obtain the maximum width of the display area corresponding to the text to be adjusted.

[0107] A mapping relationship between the font size of the text to be adjusted and the maximum width of the corresponding display area may be preset, and then the corresponding maximum width may be found from the mapping relationship based on the target font size of the text to be adjusted.

[0108] Step S430: determining the maximum number of lines corresponding to the text to be adjusted based on the specific content of the text to be adjusted.

[0109] Based on the obtained maximum width and the target font size of the text to be adjusted, the number of words that can be displayed in a line can be determined. Then, based on the specific content of the text to be adjusted and the number of words that can be displayed in a line, the maximum number of lines corresponding to the text to be adjusted can be determined.

[0110] Step S440: Obtain the line spacing, character spacing, and paragraph style of the text to be adjusted.

[0111] Step S450 , determining a target size of a display area corresponding to the text to be adjusted based on the maximum width, maximum number of lines, target font size, line spacing, character spacing, and paragraph style of the text to be adjusted.

[0112] Among them, parameters such as the maximum width, maximum number of lines, target font size, line spacing, character spacing and paragraph style of the text to be adjusted can be passed into the boundingRectWithSize function, so that the boundingRectWithSize function determines the target size of the display area corresponding to the text to be adjusted based on the maximum width, maximum number of lines, target font size, line spacing, character spacing and paragraph style.

[0113] In this embodiment, parameters such as the character spacing, baseline offset value, line breaking method, and text alignment method of the text to be adjusted can also be obtained and passed into the boundingRectWithSize function as reference parameters for determining the target size of the display area corresponding to the text to be adjusted.

[0114] In another example, a mapping relationship between the font size of the text to be adjusted and the size of the display area corresponding to the text to be adjusted can be pre-set. Then, from the mapping relationship, the size corresponding to the target font size of the text to be adjusted is found as the target size of the display area corresponding to the text to be adjusted. In the mapping relationship between the font size of the text to be adjusted and the size of the display area corresponding to the text to be adjusted, the size of the display area corresponding to the text to be adjusted can be determined based on the method corresponding to steps S410 to S450, and of course, can also be determined based on other methods.

[0115] Step S312 : determining a target size of the view to which the text to be adjusted belongs based on a target size of the display area corresponding to the text to be adjusted and a view layout relationship of the page to which the text to be adjusted belongs.

[0116] The margin (outer margin) and padding (inner margin) of the view to which the text to be adjusted belongs can be determined based on the target size of the display area corresponding to the text to be adjusted, and the target size of the view to which the text to be adjusted belongs can be determined based on the margin and padding of the view to which the text to be adjusted belongs and the view layout relationship of the page to which the text to be adjusted belongs. The larger the target size of the display area corresponding to the text to be adjusted, the smaller the margin and padding of the view to which the text to be adjusted belongs, or the smaller the target size of the display area corresponding to the text to be adjusted, the larger the margin and padding of the view to which the text to be adjusted belongs.

[0117] Step S320 : adjusting the size of the view to which the text to be adjusted belongs based on the determined target size.

[0118] After determining the target size of each view in the page to which the text to be adjusted belongs, the size of the view to which the text to be adjusted belongs is adjusted.

[0119] See also Figure 6 ,in, Figure 6 , the left side shows the font size of the text and the size of the view before adjustment, and the right side shows the font size of the text and the size of the view after adjustment.

[0120] In this embodiment, the target size of the view to which the text to be adjusted belongs is determined based on the target font size of the text to be adjusted, the view to which the text to be adjusted belongs, and the view layout relationship of the page to which the text to be adjusted belongs. Then, based on the determined target size, the size of the view to which the text to be adjusted belongs is adjusted. In this way, when the font size of the text is adjusted, the size of the view to which the text belongs is also adjusted, so that the size of the text matches the size of the view to which it belongs; and when determining the size of the view to which it belongs, the view layout relationship is referred to, so as to avoid the problem of blocking other views after the view is adjusted.

[0121] In an exemplary embodiment, if only the size of the view to which the text to be adjusted belongs is adjusted, the size of the view will not match the size of the parent view of the view. Figure 5 After step S310, the parent view of the view to which the text to be adjusted belongs may be determined first. Then, based on the target size of the view to which the text to be adjusted belongs, the target size of the corresponding parent view may be determined, and the size of the corresponding parent view may be adjusted based on the target size of the parent view. Of course, in other embodiments, the sizes of all views in the page to which the text to be adjusted belongs may also be adjusted to make the adjusted page coordinated.

[0122] See also Figure 7 , Figure 7 yes Figure 2 The flowchart of step S110 in the embodiment shown is in an exemplary embodiment. Figure 7 As shown, the process of determining the text to be adjusted whose font size is to be adjusted from the application program may include steps S111 to S112, which are described in detail as follows:

[0123] Step S111 : determining a page whose font size is to be adjusted from the application program.

[0124] The pages whose font sizes are to be adjusted may be all pages included in the application, or may be pages currently being displayed.

[0125] Alternatively, in one embodiment, step S111 may include: determining an undestroyed view controller in the key window of the application; using the page corresponding to the determined view controller as the page whose font size is to be adjusted, wherein one page corresponds to one view controller. It should be noted that the KeyWindow (key window) refers to the active window, that is, the window that can receive user input events; the KeyWindow includes a view controller (viewController), which is used to control the view, and one page corresponds to one view controller. After the view controller is created, the view controller will be destroyed when certain conditions are met. The page corresponding to the undestroyed view controller in the key window of the application can be used as the page whose font size is to be adjusted.

[0126] Step S112 , traversing the views in the page, if the display object corresponding to the traversed view is text, then using the display object as the text to be adjusted whose font size is to be adjusted.

[0127] After determining the page whose font size is to be adjusted, the views in the page may be traversed. If the display object corresponding to the traversed view is text, the display object is used as the text whose font size is to be adjusted.

[0128] In an exemplary embodiment, Figure 3 After step S140, the method for adjusting the text font size may further include steps S150 to S160, which are described in detail as follows:

[0129] Step S150 , generating text data according to the text to be adjusted after the font size is adjusted.

[0130] In this embodiment, text data is generated based on the text to be adjusted after the font size is adjusted, that is, the text to be adjusted corresponding to the target font size.

[0131] Step S160 , storing the text data so that when a font size adjustment instruction is received again, the font size of the text in the corresponding page is adjusted based on the stored text data.

[0132] After generating the text data, the text data is stored. In this way, when the font size adjustment instruction is received again, if the text to be adjusted corresponding to the font size adjustment instruction received again and the target font size corresponding to the text to be adjusted match the stored text data, the text to be adjusted can be directly drawn in the page to which the text to be adjusted belongs based on the stored text data, without the need to generate the text data again, thereby improving the speed of font size adjustment.

[0133] See also Figure 8 In an exemplary embodiment, the method for adjusting the text font size includes:

[0134] Start font switching. After receiving the font size adjustment instruction, start font switching.

[0135] Create TXFontCenter. Create TXFontCenter and initialize TXFontCenter. During the initialization process, create NSOperationQueue (operation queue) inside TXFontCenter. Then, you can use TXFontCenter to implement subsequent steps such as "add to NSOperationQueue".

[0136] Add to NSOperationQueue, where the view written to NSOperationQueue is processed first. Specifically, first traverse all undestroyed viewControllers (view controllers) in the current keyWindow (key window), and obtain the display objects corresponding to the view (view) and its subviews (subviews) in the viewController through the objc_getAssociatedObject function; if there is a text-related API (Application Programming Interface) in the display object, then use the display object as the text to be adjusted, and obtain and save the view layout relationship of the page to which the text to be adjusted belongs; then, determine the target font size of the text to be adjusted based on the font size adjustment instruction, and add the view to which the text to be adjusted belongs and the target size of the display area corresponding to the text to be adjusted to NSOperationQueue. Among them, the objc_getAssociatedObject function is an association function.

[0137] Determine whether the view to which the text to be adjusted belongs has a parent view. Here, you can obtain the view to which the text to be adjusted belongs from NSOperationQueue and determine whether the view to which the text to be adjusted belongs has a parent view.

[0138] If it exists, recursively traverse the parent view of the view to which the text to be adjusted belongs.

[0139] Modify the size of the view based on the view layout relationship. If a parent view exists, determine the target size of the view to which the text to be adjusted belongs and the parent view of the view to which the text to be adjusted belongs based on the view layout relationship, and then modify the size of the corresponding view based on the target size.

[0140] Generating text data corresponding to the target font size. Passing the target font size into the corresponding text setting program through the target program entry, so that the corresponding text setting program controls the generation of text data corresponding to the target font size for the text to be adjusted.

[0141] Write the text data into the cache. When the page to which the text to be adjusted belongs is displayed, the text data is retrieved from the cache and drawn on the page to which the text to be adjusted belongs.

[0142] The text data may also be stored, so that when a font size adjustment instruction is received again, if the font size adjustment instruction matches the text data, the text data may be directly obtained and drawn on the page.
