[0073] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0074] It should be pointed out that the embodiments of the present invention and the features in the embodiments may be combined with each other if there is no conflict.

[0075] The existing analysis methods still have the following problems:

[0076] It is not possible to analyze the images that still occupy the application memory when the application interface containing the images is left; nor is it possible to analyze the images that are not used but occupy the application memory.

[0077] In order to solve the problems existing in the prior art, an embodiment of the present invention provides a picture analysis method, such as Figure 1 As shown, the method includes:

[0078] Step S101, obtaining picture information, wherein the picture information includes an instance of a management picture class and an instance of a display picture class.

[0079] In this step, the instance of the image management class refers to an instance object of UIImage (UIImage is a class used to manage images in the IOS operating system).

[0080] Step S102: Calculate the actual amount of memory occupied by the image according to the instance of the image management class, and calculate the amount of memory to be optimized for the image according to the instance of the image management class and the instance of the image display class.

[0081] Step S103: The actual amount of memory occupied by the picture, the amount of memory to be optimized for the picture, and the picture are displayed simultaneously, and the picture is displayed using an instance of the picture management class and an instance of the picture display class.

[0082] It should be understood that the memory refers to the application memory, and the application memory refers to the terminal memory allocated to the application by the terminal to which the application belongs.

[0083] It should be noted that the specific implementation of this embodiment is described in detail below and will not be repeated here.

[0084] In the embodiment of the present invention, the information of the picture also includes the source of the picture;

[0085] Get the information of the image, including:

[0086] If it is detected that the application downloads the picture or the application reads the picture, then the instance of the management picture class and the picture source are collected;

[0087] If it is detected that the display picture class loads the picture, then an instance of the display picture class is collected;

[0088] The instance of the management picture class, the picture source and the instance of the display picture class are matched and stored.

[0089] In this embodiment, it should be understood that there are many sources of pictures, and the embodiment of the present invention can analyze pictures downloaded from the network and pictures stored locally in the application.

[0090] The instance of the image display class refers to the instance object of UIImageView (UIImageView is a class used to display images in the IOS operating system).

[0091] In this embodiment, instances of the image class and instances of the display image class are collected to determine the actual amount of application memory occupied by the image and the amount of memory to be optimized for the image, thereby improving the precision of the analysis, so that the user can know which image the actual amount of memory occupied and the amount of memory to be optimized belongs to, and the user can have a more comprehensive understanding of the image through the source of the image, further improving the user experience.

[0092] In an embodiment of the present invention, the actual amount of memory occupied by the picture, the amount of memory to be optimized for the picture, and the picture are simultaneously displayed, including:

[0093] The actual amount of memory occupied by the image, the amount of memory to be optimized for the image, and the image are simultaneously displayed on the analysis interface.

[0094] It should be noted that for each picture, the analysis interface displays the picture, the actual memory occupied by the picture, and the memory to be optimized for the picture, so that users can know what the pictures that occupy a large amount of application memory look like, which is particularly obvious when there are many pictures in the application.

[0095] In this embodiment, the actual amount of memory occupied by the image, the amount of memory to be optimized for the image, and the image are simultaneously displayed on the analysis interface, which further improves the precision of the analysis and further enhances the user experience.

[0096] In an embodiment of the present invention, the instance of the management picture class is stored in a weak reference manner;

[0097] After the actual amount of memory occupied by the picture, the amount of memory to be optimized for the picture, and the picture are simultaneously displayed, the method includes:

[0098] Controlling the terminal to which the application belongs not to display the application interface; wherein the application interface includes the picture;

[0099] If the image is displayed on the analysis interface, it is determined that the application memory of the image is not released.

[0100] In this embodiment, the instance of the management picture class is stored in a weak reference manner, and the terminal to which the application belongs is controlled not to display the application interface; the application interface contains pictures; if the picture is displayed on the analysis interface, it is determined that the application memory of the picture has not been released. In this way, the pictures that still occupy the application memory when the application interface containing the picture is left are analyzed, which further improves the precision of the analysis and further enhances the user experience.

[0101] In an embodiment of the present invention, the actual amount of memory occupied by the picture, the amount of memory to be optimized for the picture, and the picture are simultaneously displayed, including:

[0102] Simultaneously displaying the actual amount of memory occupied by the image, the amount of memory to be optimized for the image, the image, and the image source;

[0103] The image source includes at least one of the page to which the image belongs, the stack address of the image, and the name of the image.

[0104] In this embodiment, the page to which the image belongs is displayed, and the user can intuitively see which page the image is loaded.

[0105] In this embodiment, the actual memory occupied by the image, the memory to be optimized, the image and the image source are displayed simultaneously; the image source includes at least one of the page to which the image belongs, the stack address of the image and the image name. Thus, the image is displayed more comprehensively, allowing users to have a more comprehensive understanding of the image, further improving the user experience.

[0106] In an embodiment of the present invention, after collecting the instance of the management picture class and the picture source, the following steps are included:

[0107] If it is detected that the display picture class cannot load the picture, it is determined that the picture is an unused picture.

[0108] In this embodiment, it is detected that the display image class cannot load the image, and the image is determined to be an unused image, so that the unused images that occupy the application memory are analyzed, which further improves the precision of the analysis and further enhances the user experience.

[0109] In an embodiment of the present invention, calculating the actual amount of memory occupied by the picture according to the instance of the picture management class, and calculating the amount of memory to be optimized for the picture according to the instance of the picture management class and the instance of the picture display class, includes:

[0110] Multiply the image length, the image scaling factor, the image width, the image scaling factor, and the number of bytes occupied per pixel, and obtain the product as the actual memory usage of the image;

[0111] Multiply the image display length, the scaling factor of the image, the image display width, the scaling factor of the image and the number of bytes occupied per pixel, and obtain the product as the minimum memory occupied by the image;

[0112] Subtract the actual memory usage of the image from the minimum memory usage of the image, and use the difference as the memory usage to be optimized for the image;

[0113] The instance of the management picture class includes the picture length, the picture width and the scaling factor of the picture, and the instance of the display picture class includes the picture display length and the picture display width.

[0114] In this embodiment, the specific implementation is as follows:

[0115] The actual amount of memory occupied by the image = image length × image scaling factor × image width × image scaling factor × number of bytes per pixel;

[0116] The minimum memory usage of an image = image display length × image scaling factor × image display width × image scaling factor × number of bytes per pixel;

[0117] The amount of memory to be optimized for the image = the actual amount of memory occupied by the image - the minimum amount of memory occupied by the image.

[0118] The unit of the image length and image width is pt. The value obtained by multiplying the image length by the image scaling factor is the pixel points in the first direction. The value obtained by multiplying the image width by the image scaling factor is the pixel points in the second direction. The first direction is perpendicular to the second direction.

[0119] The length and width of the image are obtained by using the size attribute in the instance of the image class, the scaling factor of the image is obtained by using the scale attribute in the instance of the image class, and the number of bytes occupied per pixel is obtained by using the API CGImageGetBitsPerPixel provided by the terminal (Apple) to which the application belongs.

[0120] If the amount of memory to be optimized for images is 0, it is determined that the application memory occupied by the images cannot be optimized; if the amount of memory to be optimized for images is a positive number, it is determined that the application memory occupied by the images can be optimized, and the amount of memory to be optimized for images is the application memory space that can be optimized.

[0121] In this embodiment, by managing the image length, image width and scaling factor in the instance of the image class, as well as the image display length and image display width in the instance of the display image class, and the number of bytes occupied per pixel, the actual amount of memory occupied by the image and the amount of memory to be optimized are determined, thereby further improving the precision of the analysis and further enhancing the user experience.

[0122] In order to solve the problems existing in the prior art, another embodiment of the present invention provides a picture analysis method. The embodiment of the present invention can be applied to a first terminal, and the first terminal can be any terminal.

[0123] like Figure 2 As shown, the method includes:

[0124] Step S201: The application downloads the picture through the network, or the application reads the picture from the local computer, and the application allocates application memory for the picture.

[0125] Specifically, the application reads the image from the local computer through the application memory or disk.

[0126] Step S202: Figure 3 As shown, the first terminal detects that an application downloads a picture or reads a picture, and uses existing acquisition technology to collect and manage instances of the picture class, the page to which the picture belongs, the stack address of the picture, and the picture name from the application; and sets the picture tag to S (S means unused or read); the first terminal stores the instance of the picture class, the page to which the picture belongs, the stack address of the picture, the picture name, and the picture tag in a matching manner in NSMapTable; wherein the instance of the picture class is stored in a weak reference manner.

[0127] Specifically, the first terminal detects, using an existing detection method, that an application downloads a picture or an application reads a picture.

[0128] The picture name can also be replaced with a picture uniform resource locator (URL). In addition, when collecting and storing the picture name, the time, local or network, etc. can also be collected and stored.

[0129] Through the stack address of the image, developers can quickly find the code where the image is located.

[0130] It should be understood that storing the instance of the picture management class in a weak reference manner means that as long as objects other than NSMapTable do not point to the instance of the picture management class, the application memory of the picture is released.

[0131] If the instance of the picture management class is stored in a strong reference mode, the application memory of the picture will not be released regardless of whether objects other than NSMapTable point to the instance of the picture management class. The application memory of the picture will be released only when NSMapTable and objects other than NSMapTable do not point to the instance of the picture management class. Therefore, if the instance of the picture management class is stored in a strong reference mode, the effect of the present invention cannot be achieved.

[0132] The object may be an instance of a display picture class, etc.

[0133] Step S203: Figure 4 As shown, the first terminal detects that the display picture class loads a picture, and uses existing collection technology to collect instances of the display picture class from the application; the instance of the display picture class is matched and stored with the instance of the management picture class in the NSMapTable, the page to which the picture belongs, the stack address of the picture, the picture name and the picture tag, and the picture tag is updated to W (W means used).

[0134] Specifically, the first terminal detects that a display picture class loads a picture using an existing detection method.

[0135] It should be understood that displaying the image class loads the image, which means that the image is displayed, that is, the image is used.

[0136] NSMapTable is a key-value pair collection. Specifically, the instance of the image management class can be used as the key, and the instance of the image display class, the page to which the image belongs, the stack address of the image, the image name and the image tag can be used as the value. The key is stored in a weak reference manner. If the key is stored in a strong reference manner, the image will occupy the application memory for a long time, and the effect of the embodiment of the present invention cannot be achieved.

[0137] Step S204: Figure 5 As shown, the first terminal reads the instance of the picture management class, the instance of the picture display class, the page to which the picture belongs, the stack address of the picture, the picture name and the picture tag from NSMapTable; calculates the actual memory occupied by the picture according to the instance of the picture management class, and calculates the memory amount of the picture to be optimized according to the instance of the picture management class and the instance of the picture display class; the first terminal displays the picture, the actual memory occupied by the picture, the memory amount to be optimized, the page to which the picture belongs, the stack address of the picture, the picture name and the picture tag on the analysis interface at the same time; and displays the picture using the instance of the picture management class and the instance of the picture display class.

[0138] Specifically, using the existing technology, the image is displayed by using an instance of the management image class and an instance of the display image class. In addition, the analysis interface is set in the first terminal.

[0139] Perform corresponding processing according to the display of the analysis interface. For example, delete the picture marked as S. For another example, optimize the application memory according to the amount of memory to be optimized for the picture.

[0140] Step S205: manually or automatically controlling the terminal to which the application belongs to not display the application interface containing the image.

[0141] Specifically, the terminal to which the application belongs is controlled to display interfaces other than the application interface containing the picture, for example, display a calendar.

[0142] Automatically controlling a terminal to which an application belongs so as not to display an application interface including a picture includes: sending an instruction to the terminal to which the application belongs, wherein the instruction is used to make the terminal to which the application belongs not to display the application interface including the picture.

[0143] Step S206: If the picture is displayed on the analysis interface, the first terminal determines that the application memory of the picture is not released.

[0144] It should be noted that since the instance of the image management class is stored in a weak reference manner, the display of the image requires the use of the instance of the image management class. Therefore, if the application memory of the image is not released, the first terminal can obtain the instance of the image management class, and the analysis interface will inevitably display the image; if the application memory of the image is released, the first terminal cannot read the instance of the image management class, and the analysis interface will inevitably not display the image. In other words, the analysis interface only displays the images that occupy the application memory.

[0145] It should be understood that if the analysis interface does not display the picture, it is determined that the application memory of the picture is released.

[0146] In addition, the image is displayed on the analysis interface and can be determined by manual observation or by existing detection methods.

[0147] Furthermore, in NSMapTable, pictures marked as S are unused pictures that occupy application memory. This is because when the application downloads the picture or reads the picture locally, application memory is allocated for the picture. In another embodiment, for pictures marked as S in NSMapTable, after verification by R&D personnel, it is finally determined that the picture is unused but occupies application memory. In NSMapTable, pictures marked as W are all used pictures.

[0148] The following is a detailed introduction to the existing analysis methods:

[0149] Instruments is a very powerful performance analysis and debugging tool provided by Apple, which is specially used for offline performance analysis. It consists of multiple small tools, Allocations is one of them, and Allocations can be used to analyze the memory usage of applications.

[0150] Allocations classifies the data in the application that occupies the application memory according to the data type, counts the amount of application memory occupied by each type of data, and generates a list based on the amount of memory occupied. Users can view VM:CG raster data or VM:ImageIO_PNG_Data in the list to see the amount of application memory occupied by image data in the application and the allocation method of application memory (for example, the name of the allocation method).

[0151] In order to solve the problems existing in the prior art, an embodiment of the present invention provides an image analysis device, such as Figure 6 As shown, the device comprises:

[0152] The acquisition unit 601 is used to acquire information of a picture, where the information of the picture includes an instance of a management picture class and an instance of a display picture class.

[0153] The processing unit 602 is used to calculate the actual amount of memory occupied by the image according to the instance of the management image class, and calculate the amount of memory to be optimized for the image according to the instance of the management image class and the instance of the display image class.

[0154] The analyzing unit 603 is used to simultaneously display the actual amount of memory occupied by the picture, the amount of memory to be optimized for the picture, and the picture, and to display the picture using an instance of the picture management class and an instance of the picture display class.

[0155] In the embodiment of the present invention, the information of the picture also includes the source of the picture;

[0156] The acquisition unit 601 is used for:

[0157] If it is detected that the application downloads the picture or the application reads the picture, then collecting the instance of the management picture class and the source of the picture;

[0158] If it is detected that the display picture class loads the picture, then an instance of the display picture class is collected;

[0159] The instance of the management picture class, the picture source and the instance of the display picture class are matched and stored.

[0160] In this embodiment of the present invention, the analysis unit 603 is used to:

[0161] The actual amount of memory occupied by the image, the amount of memory to be optimized for the image, and the image are simultaneously displayed on the analysis interface.

[0162] In an embodiment of the present invention, the instance of the management picture class is stored in a weak reference manner;

[0163] The analysis unit 603 is used for:

[0164] After simultaneously displaying the actual amount of memory occupied by the picture, the amount of memory to be optimized for the picture, and the picture, controlling the terminal to which the application belongs not to display the application interface; wherein the application interface includes the picture;

[0165] If the image is displayed on the analysis interface, it is determined that the application memory of the image is not released.

[0166] In this embodiment of the present invention, the analysis unit 603 is used to:

[0167] Simultaneously displaying the actual amount of memory occupied by the image, the amount of memory to be optimized for the image, the image, and the image source;

[0168] The image source includes at least one of the page to which the image belongs, the stack address of the image, and the name of the image.
