[0036] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In iOS development, the controls of the application interface need to adapt to a variety of theme styles, and the colors of the controls (including text color, background color, etc.) need to be dynamically adjusted with the theme color. In addition, some controls need to be mixed with the theme color according to their original colors to achieve more complex color adjustment visual effects, such as transparency gradient or multi-layer mixing.

[0038] In the related art, dynamic color mixing is usually achieved by pre-calculating the color mixing result of the control according to the theme color, storing it and assigning it to the control when the theme changes. For example, the developer needs to pre-calculate the control color under different transparency, different theme colors, and various combinations of the control's initial color, and pre-store all calculation results in the application.

[0039] However, the above solution requires offline calculation and storage of a large number of color combinations in advance, resulting in a waste of storage space and increasing the occupation of system resources.

[0040] In the embodiment of the present invention, based on the core technical concept of selecting an adaptive drawing tool according to the control type and drawing content and determining the target context corresponding to the color adjustment requirement, the control color adjustment method in the related art is improved. The present invention will be described in detail below with reference to the accompanying drawings:

[0041] Reference Figure 1 , shows a flowchart of a control color adjustment method provided by some embodiments of the present invention, which may specifically include the following steps:

[0042] Step 101, determining a target control in a control list, and determining the control type and drawing content of the target control; wherein the drawing content is visual information that the target control needs to display;

[0043] In a specific implementation, controls that require color adjustment may include but are not limited to text controls, image controls, and view area controls, and therefore, the controls that require color adjustment may be counted first to obtain an original control list. For example, the contents of an original control list may include: UILabel control, UIView control, UIImage control, CALayer control, custom control A, and custom control B.

[0044] On this basis, the controls in the original control list can be converted to unify the drawing method of the controls into a drawing method using the context, thereby reducing the difficulty of management and improving the efficiency of color adjustment; generally speaking, each control is a subclass of UIView or a subclass of CALayer, and their drawing method is essentially implemented by using the context provided by the system, that is, each control has a series of drawing functions inherited from UIView or CALayer. For example, for the UIView series of controls, a more common example of its drawing series function is func draw(_rect:CGRect), hereinafter referred to as draw(_:), and for the CALayer control, a more common example of its drawing series function is func draw(in rect:CGRect), hereinafter referred to as draw(in:); and CALayer also includes the CALayerDelegate proxy function: -(void)drawLayer:(CALayer*)layer inContext:(CGContextRef)ctx; hereinafter referred to as draw(_:in:).

[0045] Therefore, you can traverse each control in the original control list, and add additional logic to the control's drawing function by rewriting the corresponding drawing function or replacing the drawing function through method swapping technology: generate context or obtain context from other channels to use context to achieve drawing, and then set the specific drawing process of each control on this basis. It should be emphasized that in addition to method swapping technology (swizzle), hooks, runtime dynamic detection technology (KVO, KVC), decompilation technology and aspect technology can also be used to achieve replacement functions.

[0046] Furthermore, after completing the conversion of the controls in the original control list through the rewritten drawing function, a control list consisting of controls whose drawing methods are all using the context drawing method is obtained. At this time, the target control that needs to be color adjusted can be determined in the control list, and the control type and drawing content of the target control can be determined to implement the subsequent color adjustment control process; specifically, the control list is established according to the control type, and the drawing content is the visual information that the target control needs to display, such as text content, image content, etc.

[0047] In some embodiments of the present invention, before determining the target control in the control list, the method further includes:

[0048] An original control list is obtained, and controls in the original control list are converted to obtain the control list; wherein the conversion process is used to convert the drawing mode of the controls into a drawing mode using a context.

[0049] In actual applications, controls that need to be adjusted in color may include but are not limited to text controls, image controls, and view area controls. Therefore, the controls that need to be adjusted in color may be counted first to obtain an original control list. For example, the content of an original control list may be: UILabel control, UIView control, UIImage control, CALayer control, custom control A, and custom control B.

[0050] On this basis, the controls in the original control list can be converted to unify the drawing method of the controls into a drawing method using a context, thereby reducing the difficulty of management and improving the efficiency of color adjustment.

[0051] In some embodiments of the present invention, converting the controls in the original control list to obtain the control list includes:

[0052] Determine a drawing function of the control, and rewrite the drawing function to add relevant logic for applying the context;

[0053] According to the rewritten drawing function, the controls are converted to obtain the control list.

[0054] In actual applications, the controls in the original control list can be converted to unify the drawing method of the controls into a drawing method using the context, thereby reducing the difficulty of management and improving the efficiency of color adjustment; generally speaking, each control is a subclass of UIView or a subclass of CALayer, and their drawing method is essentially implemented by using the context provided by the system, that is, each control has a series of drawing functions inherited from UIView or CALayer. For example, for the UIView series of controls, a more common example of its drawing series function is funcdraw(_rect:CGRect), hereinafter referred to as draw(_:), and for the CALayer control, a more common example of its drawing series function is func draw(in rect:CGRect), hereinafter referred to as draw(in:); and CALayer also includes the CALayerDelegate proxy function: -(void)drawLayer:(CALayer*)layer inContext:(CGContextRef)ctx; hereinafter referred to as draw(_:in:).

[0055] Therefore, each control in the original control list can be traversed, and additional logic can be added to the control's drawing function by rewriting the corresponding drawing function or replacing the drawing function through method swapping technology: generating context or obtaining context from other channels to use context to achieve drawing, and then setting the specific drawing process of each control on this basis. It should be emphasized that in addition to method swapping technology (swizzle), hooks, runtime dynamic detection technology (KVO, KVC), decompilation technology and aspect technology can also be used to achieve replacement functions. After completing the conversion of the controls in the original control list through the rewritten drawing function, a control list consisting of controls whose drawing methods are all using the context drawing method is obtained.

[0056] Step 102, determining a drawing tool to be used for the target control according to the control type and drawing content, and determining a target context corresponding to the color adjustment requirement in response to a color adjustment requirement of the target control;

[0057] In the specific implementation, based on the above content, the premise for the control in the control list to achieve drawing is to obtain the corresponding context, that is, the context is the basis for all drawing of the control. How to obtain the context needs to be determined according to different situations, for example:

[0058] (1) For basic controls and custom controls inherited from UIView in the control list

[0059] You can rewrite its draw(_:) method so that the system automatically provides a context, and this context is the "current context";

[0060] (2) For basic controls and custom controls that inherit from CALayer in the control list

[0061] You can override the draw(in:) method or the draw(_:in:) method and pass the context as a function parameter. However, no matter which method you override, the context is not the "current context".

[0062] (3) For images or other drawing areas that need to be drawn immediately

[0063] You can use the UIGraphicsImageRenderer class to call the image(actions:) function for drawing. The system can automatically provide a context, and this context is the "current context"; the full name of the function is as follows:

[0064] func image(actions:(UIGraphicsImageRendererContext)->Void)->UIImage;

[0065] Furthermore, the drawing tools used in the embodiments of the present invention may include:

[0066] UIKit drawing tools:

[0067] UIKit provides some self-drawing tools, which have their own drawing functions and are easy to use. For example: UIImage, NSString, UIBezierPath and UIColor, so you can call the drawing function directly without the explicit participation of the context, but you need to use the current context. That is, when using UIKit tools to draw, you generally need to draw on the "current context" to take effect. If the context is not the "current context", the drawing will not take effect.

[0068] Core Graphics:

[0069] Core Graphics, also known as Quartz 2D, includes all 2D drawing tools, which are composed of C functions and are a superset of UIKit drawing tools. There is a requirement for drawing with this set of tools: it does not need to appear in the "current context", but it requires a context that appears in plain text (i.e. plain text context).

[0070] On this basis, the drawing tool to be used by the target control can be determined according to the control type and drawing content of the target control. For example, Figure 2 As shown, for controls inherited from UIView, if the drawing content is text or other simple drawing content, UIKit's drawing tools can be used. From the perspective of drawing content, functions that can be covered by functions such as UIImage, NSString, UIBezierPath, UIColor, etc. can all be stripped out and processed using UIKit's drawing tools, and the processing location is: put in UIView's draw(_:) method. However, this step is optional and can be determined according to the actual application situation. Because all functions that can be implemented using UIKit's drawing tools can be implemented through CoreGraphics. The rest of the drawing content that cannot be processed by UIKit drawing tools can be processed using CoreGraphics after being stripped out, because Core Graphics requires a plaintext context; therefore, if the current position is in the draw(_:) method of UIView, a plaintext context can be obtained through the UIGraphicsGetCurrentContext method; and if the current position is in the image(actions:) function of UIGraphicsImageRenderer, the input parameter can be obtained, which is the plaintext context; or the UIGraphicsGetCurrentContext method can be called to obtain a plaintext context.

[0071] Further, such as Figure 3As shown, for controls inherited from CALayer, if the drawing content is text or more complex drawing content, UIKit controls can be used; and from the perspective of drawing content, for functions that can be covered by UIImage, NSString, UIBezierPath, UIColor and other functions, they can be processed using UIKit drawing tools after being stripped out, and the processing location can be placed in CALayer's draw(in:) method or CALayerDelegate proxy function draw(_:in:). As mentioned earlier, in CALayer's draw(in:) method or CALayerDelegate proxy function draw(_:in:), although context appears in plain text, it is not the "current context", so in order to make the context the "current context", UIGraphicsPushContext(_:) needs to be called, and when it is finished, UIGraphicsPopContext needs to be called. Then you can strip out the rest of the content that can't be processed by UIKit drawing tools and use Core Graphics for processing. Since it requires a plaintext context, if the current position is in: CALayer's draw(in:) method or CALayerDelegate proxy function draw(_:in:), you can choose to get its input parameter, which is a plaintext context, or call the UIGraphicsGetCurrentContext method to get a plaintext context. If the current position is in: UIGraphicsImageRenderer's function image(actions:), you can choose to get its input parameter, which is a plaintext context, or call the UIGraphicsGetCurrentContext method to get a plaintext context.

[0072] After the above steps, you can determine the drawing tool to be used by the target control and get the original context corresponding to the drawing tool. Then, you can set the parameters of the original context according to the color adjustment requirements of the target control to get the target context, and implement subsequent control based on the target context. Specifically, both the UIKit drawing tool and the CoreGraphics drawing tool have methods for setting context, but the forms are different. Therefore, the following will take CoreGraphics as an example for explanation:

[0073] (1) Original coloring

[0074] When drawing the content of a control that requires color mixing, the use of colors is generally involved, for example:

[0075] Set the fill color:

[0076] context.setFillColor(xx.cgColor);

[0077] Set the stroke color:

[0078] context.setStrokeColor(xx.cgColor);

[0079] (2) Add transparency

[0080] You can add the steps to set the context transparency (alpha) after the color setting:

[0081] context.setAlpha (transparency value): Transparency determines the color mixing scheme. Assuming there are two layers, if the transparency is set to 0, the color of the lower layer is completely adopted. If the transparency is 1, the color of the upper layer is completely adopted. If the transparency is other values ​​​​between 0-1, the color mixing result calculation formula can be:

[0082] result=alpha*upper+(1-alpha)*lower

[0083] And the color mixing result calculation formula can be changed to be more complicated, such as:

[0084] result = coefficient 1*alpha*upper + coefficient 2*(1-alpha)*lower

[0085] By changing this formula and adding more layers, you can define a very complex color mixing scheme. The default mode can be the simplest mode mentioned above. For example, for multiple layers, you can start from the bottom layer and use the results of the bottom two layers as the input for comparison with the third layer above. You can calculate the final transparency of multiple layers. You can also form a result for each adjacent two layers for multiple layers (if there are an odd number of layers, they will not be included in the calculation and enter the next result list), and then gather the results into a new list, and then perform adjacent calculations on the elements in the list again until a final result is obtained.

[0086] Through the above steps, the target context corresponding to the color adjustment requirement can be determined, which can be used in the subsequent color adjustment control process.

[0087] In some embodiments of the present invention, before determining the target context corresponding to the color adjustment requirement in response to the color adjustment requirement of the target control, the method further includes:

[0088] According to the drawing tool, context type information corresponding to the drawing tool is determined; wherein the context type information at least includes a plaintext context type and a current context type.

[0089] In actual applications, the drawing tool to be used by the target control can be determined according to the control type and drawing content of the target control, and the context type information corresponding to the drawing tool can be further determined according to the drawing tool, that is, whether the drawing tool needs to use the plaintext context type (plaintext context) or the current context type (current context). For example, Figure 2 As shown, for controls inherited from UIView, if the drawing content is text or other simple drawing content, UIKit's drawing tools can be used. From the perspective of drawing content, the functions that can be covered by functions such as UIImage, NSString, UIBezierPath, UIColor, etc. can all be stripped out and processed using UIKit's drawing tools, and the processing location is: put in UIView's draw(_:) method. However, this step is optional and can be determined according to the actual application situation. Because all functions that can be implemented using UIKit's drawing tools can be implemented through Core Graphics. The rest of the drawing content that cannot be processed by UIKit drawing tools can be processed using Core Graphics after being stripped out, because Core Graphics requires a plaintext context; therefore, if the current position is in: UIView's draw(_:) method, you can get a plaintext context through the UIGraphicsGetCurrentContext method; and if the current position is in: UIGraphicsImageRenderer's function image(actions:), you can get its input parameter, which is the plaintext context; or call the UIGraphicsGetCurrentContext method to get a plaintext context.

[0090] Further, such as Figure 3As shown, for controls inherited from CALayer, if the drawing content is text or more complex drawing content, UIKit controls can be used; and from the perspective of drawing content, for functions that can be covered by UIImage, NSString, UIBezierPath, UIColor and other functions, they can be processed using UIKit drawing tools after being stripped out, and the processing location can be placed in CALayer's draw(in:) method or CALayerDelegate proxy function draw(_:in:). As mentioned earlier, in CALayer's draw(in:) method or CALayerDelegate proxy function draw(_:in:), although context appears in plain text, it is not the "current context", so in order to make the context the "current context", UIGraphicsPushContext(_:) needs to be called, and when it is finished, UIGraphicsPopContext needs to be called. Then you can strip out the rest of the content that can't be processed by UIKit drawing tools and use Core Graphics for processing. Since it requires a plaintext context, if the current position is in: CALayer's draw(in:) method or CALayerDelegate proxy function draw(_:in:), you can choose to get its input parameter, which is a plaintext context, or call the UIGraphicsGetCurrentContext method to get a plaintext context. If the current position is in: UIGraphicsImageRenderer's function image(actions:), you can choose to get its input parameter, which is a plaintext context, or call the UIGraphicsGetCurrentContext method to get a plaintext context.

[0091] In some embodiments of the present invention, determining the target context corresponding to the color adjustment requirement includes:

[0092] An original context corresponding to the drawing tool is determined according to the context type information, and the target context is determined according to the original context and the color adjustment requirement.

[0093] In actual applications, the drawing tool to be used by the target control can be determined according to the control type and drawing content of the target control, and the context type information corresponding to the drawing tool can be further determined according to the drawing tool, that is, whether the drawing tool needs to use the plaintext context type (plaintext context) or the current context type (current context), and then the corresponding original context is obtained according to the corresponding context type. For example, Figure 2 As shown, for controls inherited from UIView, if the drawing content is text or other simple drawing content, UIKit's drawing tools can be used. From the perspective of drawing content, the functions that can be covered by functions such as UIImage, NSString, UIBezierPath, UIColor, etc. can all be stripped out and processed using UIKit's drawing tools, and the processing location is: put in UIView's draw(_:) method. However, this step is optional and can be determined according to the actual application situation. Because all functions that can be implemented using UIKit's drawing tools can be implemented through Core Graphics. The rest of the drawing content that cannot be processed by UIKit drawing tools can be processed using Core Graphics after being stripped out, because Core Graphics requires a plaintext context; therefore, if the current position is in: UIView's draw(_:) method, you can get a plaintext context through the UIGraphicsGetCurrentContext method; and if the current position is in: UIGraphicsImageRenderer's function image(actions:), you can get its input parameter, which is the plaintext context; or call the UIGraphicsGetCurrentContext method to get a plaintext context.

[0094] In some embodiments of the present invention, determining the target context according to the original context and the color adjustment requirement includes:

[0095] According to the color adjustment requirement, parameters of the original context are set to obtain the target context, wherein the parameters at least include a color parameter and a transparency parameter.

[0096] In actual applications, after determining the drawing tool to be used by the target control and obtaining the original context corresponding to the drawing tool, the parameters of the original context can be set according to the color adjustment requirements of the target control to obtain the target context, and subsequent control can be implemented according to the target context; specifically, both the UIKit drawing tool and the Core Graphics drawing tool have methods for setting context, but the forms are different. Therefore, the following will take Core Graphics as an example for explanation:

[0097] (1) Original color filling (color parameter setting)

[0098] When drawing the content of a control that requires color mixing, the use of colors is generally involved, for example:

[0099] Set the fill color:

[0100] context.setFillColor(xx.cgColor);

[0101] Set the stroke color:

[0102] context.setStrokeColor(xx.cgColor);

[0103] (2) Transparency added (transparency parameter setting)

[0104] You can add the steps to set the context transparency (alpha) after the color setting:

[0105] context.setAlpha (transparency value): Transparency determines the color mixing scheme. Assuming there are two layers, if the transparency is set to 0, the color of the lower layer is completely adopted. If the transparency is 1, the color of the upper layer is completely adopted. If the transparency is other values ​​​​between 0-1, the color mixing result calculation formula can be:

[0106] result=alpha*upper+(1-alpha)*lower

[0107] And the color mixing result calculation formula can be changed to be more complicated, such as:

[0108] result = coefficient 1*alpha*upper + coefficient 2*(1-alpha)*lower

[0109] By changing this formula and adding more layers, you can define a very complex color mixing scheme. The default mode can be the simplest mode mentioned above. For example, for multiple layers, you can start from the bottom layer and use the results of the bottom two layers as the input for comparison with the third layer above. You can calculate the final transparency of multiple layers. You can also form a result for each adjacent two layers for multiple layers (if there are an odd number of layers, they will not be included in the calculation and enter the next result list), and then gather the results into a new list, and then perform adjacent calculations on the elements in the list again until a final result is obtained.

[0110] Through the above steps, the target context corresponding to the color adjustment requirement can be determined, which can be used in the subsequent color adjustment control process.

[0111] Step 103: Control the drawing tool to adjust the color of the target control according to the target context.

[0112] In the specific implementation, after setting the relevant parameters to determine the final target context, the drawing tool can be controlled according to the target context to adjust the color of the target control. Specifically, since the transparency and color mixing scheme have been specified on the context, the system can directly calculate the final result (i.e., the color mixing result) for the newly added color when adjusting the color. That is, the original target control has one color, and when the new color is added, it only needs to directly assign the new color to the target control, and then call the corresponding refresh function provided by the system (such as setNeedsDisplay / layoutIfNeeded, etc.), without calculation.

[0113] For example, in actual use, if there is no color mixing scheme and you want the new color to become the color of the control directly, you can simply set the alpha here to 1. If there is a color mixing scheme and you want the new color to be mixed with the old color and then become the color of the control, you can set the alpha here to the alpha value calculated by the color mixing result calculation formula in the previous step. If there is no color mixing scheme and you do not want the new color to affect the old color, you can set the alpha here to 0.

[0114] Furthermore, after a round of statistics, the alpha value corresponding to each control can be recorded in a mapping relationship to facilitate synchronization with other devices and app versions, as well as saving and other operations; the mapping relationship between the control type of the target control and the drawing tool can also be archived to facilitate direct calls in response to subsequent similar or identical control color adjustment requirements.

[0115] In some embodiments of the present invention, the method further comprises:

[0116] A mapping relationship between the control type of the target control and the drawing tool is determined, and the mapping relationship is archived.

[0117] In actual applications, as mentioned above, after a round of statistics, the alpha value corresponding to each control can be recorded in a mapping relationship to facilitate synchronization with other devices and app versions, as well as saving and other operations; the mapping relationship between the control type of the target control and the drawing tool can also be archived to facilitate direct calls in response to subsequent similar or identical control color adjustment requirements.

[0118] In an embodiment of the present invention, a target control is determined in a control list, and the control type and drawing content of the target control are determined; wherein the drawing content is the visual information that the target control needs to display; then, according to the control type and the drawing content, the drawing tool to be used for the target control is determined, and in response to the color adjustment demand of the target control, the target context corresponding to the color adjustment demand is determined; thereby, the color of the target control is adjusted in real time by controlling the drawing tool according to the target context, and an appropriate drawing tool can be selected according to the control type and the drawing content, and the target context corresponding to the color adjustment demand can be determined, and then the control color adjustment can be achieved by directly controlling the drawing tool through the target context, without the need to calculate and store a large number of color combinations offline in advance, thereby avoiding the waste of storage space, reducing the occupation of system resources, and improving the efficiency of control color adjustment.
