Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method for determining a presentation time and a method and an apparatus for determining a page rendering completion time.
Background
At present, a mobile terminal can be provided with a plurality of Applications (APP), and the quality of application performance can affect the use experience of a user. The application starting time and the page switching time are two important indexes in the application performance.
Currently, in an IOS operating system, the time-consuming process of acquiring application start is generally as follows: acquiring application starting time; and acquiring the time of calling the 'viewDidAppear function' by the application, and taking the time as the application starting completion time. And taking the difference value of the application starting completion time and the application starting time as the application starting time consumption.
Currently, in an IOS operating system, a time-consuming process for acquiring page switching generally includes: acquiring the starting time of page switching; and acquiring the time of calling the 'viewDidAppear function' by the application, and taking the time as the page switching completion time. And taking the difference value of the page switching completion time and the page switching start time as the page switching time consumption.
However, during application startup or page switching, an application calls the "viewdidappper function" to simply indicate that the page layout logic has completed. At the moment, the page is not rendered, and the user can view the page after the page rendering is completed. For the IOS system, the operating system does not provide any callback interface for rendering completion, so the callback interface cannot be used to obtain the page rendering completion time.
For the user, the application calls the "viewDidAppear function" time instead of the application start completion time or the page switch completion time felt by the user; therefore, the application startup time and the page switching time determined by the prior art scheme are inaccurate.
Disclosure of Invention
The inventor of the application finds out in the research process that:
adding codes in each module of the application which consumes time for starting the page or consuming time for starting the application, recording a timestamp of a page refreshed by the application by using the added codes after the application receives a network request response sent by a server, and determining the timestamp of the refreshed page as page switching completion time or application starting completion time.
According to the scheme, the time stamp for refreshing the page is later than the time for calling the 'viewDidAppear function' by the application, but the time stamp for refreshing the page is still earlier than the page rendering completion time. Moreover, codes need to be added to modules which consume time for starting each application page or application, and the implementation process is complicated.
Therefore, the time consumed by starting the application and the time consumed by switching the page, which are determined based on the scheme, are still inaccurate, and code invasion can be caused to modules in the application.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
To facilitate understanding by those skilled in the art, the present application provides a mobile terminal that uses an IOS operating system. Referring to fig. 1, the mobile terminal includes a plurality of applications, and each application may include a plurality of existing modules implementing service functions.
In order to avoid the generation of intrusion codes on an original module, a new module is added in the application, and the module is used for calculating the time consumed by page switching and the time consumed by application starting. Other modules which need to use the time-consuming page switching or the time-consuming application starting can acquire the time-consuming page switching or the time-consuming application starting from the modules.
According to an embodiment provided by the present application, a first embodiment of a method for determining a presentation time is provided. The method is integrated in modules (namely new modules) outside original modules in the application of the IOS system. Referring to fig. 2, the method specifically includes the following steps:
step S201: an operation start time is acquired.
When the user triggers the application icon, the user is indicated as opening the application at present, so that the application start time can be acquired.
The first implementation mode comprises the following steps: the time when the "main function" is called is determined as the application start time.
The application calls the "main function" during the application opening process, so the module can monitor the "main function" and record the time when the "main function" is called, and take the time as the application start time.
The second implementation mode comprises the following steps: and recording the time for calling the loading function of the class, and determining the time as the starting time of the application.
The binary file is loaded in the application opening process, and according to the objective-critical time principle in the IOS system, the application actively calls the 'class loading function' when the IOS operating system loads the binary file. Therefore, the module monitors the class loading function and determines the time for calling the class loading function as the application starting time.
Since the time for calling the "class loading function" is before the time for calling the "main function", the application start time determined by the implementation mode is closer to the time when the user clicks the application icon.
And acquiring the starting time of page switching under the condition that the user triggers the application sub-page to trigger the page switching.
Depending on the situation that the user triggers the sub-page, the application may call a "push function", "tab function", or "addChildViewController function" when performing page switching.
Therefore, the module monitors a function (e.g., "push function", "tab function", or "adddevidviewcontroller function") indicating page switching, and records the call time of the function indicating page switching as the page switching start time.
Step S202: and acquiring the completion time of the page layout logic.
The application receives the network response sent by the server after sending the network request to the server, and carries out page layout according to the network response.
After the page layout logic is complete, the application will call a function, such as: "viewdidlayutreviews function", "layoutreviews function", or "viewdidappper function".
Thus, the module monitors a function (e.g., "viewDidLayoutSubvious function," "layoutSubvious function," or "viewDidAppear function") indicating the completion of the page layout logic, and records the time when the function is called, which is determined as the page layout logic completion time.
Step S203: and in the page rendering process, sampling operation is carried out on a preset pixel point set, and sampling time and a pixel value set corresponding to the preset pixel point set are recorded.
Because the IOS system does not have any callback interface after the rendering is finished, the technical scheme provided by the inventor of the application is as follows: the pixel value of the pixel point can be changed continuously in the process of rendering, and after the rendering process is finished, the pixel value of the pixel point is not changed any more. Therefore, whether the rendering process is completed is determined by whether the pixel value is changed.
After the page layout logic is complete, the application will perform a page rendering process. A plurality of pixels can be preset and form a preset pixel point set. The positions of a plurality of pixel points in the preset pixel point set are not limited.
Preferably, the pixels in the predetermined pixel set are distributed in different areas of the display screen, for example, the display screen is divided into four areas, i.e., an upper area, a lower area, a left area and a right area, and one pixel can be selected from the four areas respectively. Therefore, whether each area is rendered can be comprehensively known.
It can be understood that the more the number of the pixels in the preset pixel set, the more the subsequent comparison process, the more the CPU resources of the terminal are consumed, so the preset pixel set can include one pixel, and thus the comparison process can be executed only on one pixel, so that the comparison process is simple and convenient.
During the rendering process, a sampling operation may be performed on a set of preset pixel points, and a sampling time and a set of pixel values of the set of preset pixel points may be recorded. In the RGB mode, the pixel value set is a specific value of RGBR, where R is a red value, G is a green value, B is a blue value, RGB is between 0-255, R is transparency, and R is between 0-1.
The sampling period may be fixed in the usual case, for example 50ms or 100ms, for example 50ms as shown in fig. 3 a. The module then performs a comparison operation on the periodically obtained sets of pixel values. When the terminal performance is higher, the terminal is not affected.
Under the condition that the performance of the terminal is not good, the operation of periodically obtaining a plurality of pixel value sets is continuously compared, and great pressure is caused to the operation of a terminal CPU.
Referring to fig. 3b, the present embodiment proposes that the periodic sampling of the screen pixel values may be started with a period of 3 times 50ms, 4 times 100ms, and 5 times 150 ms. Since the rendering process is fast at the beginning of rendering, the sampling frequency is high, and the subsequent rendering process is slow, the sampling frequency is gradually reduced.
Assuming that 5 sampling operations are performed, see table 1, for the sampling time and pixel value set (for example, the preset pixel point set includes one pixel point) represented visually.
TABLE 1
Step S204: and judging whether the pixel value set of the preset pixel point set is not changed any more, if so, entering step S205, and otherwise, entering step S204.
After obtaining the sampling time 10050ms and the pixel value set 1 after the first sampling, and obtaining the sampling time 10100ms and the pixel value set 2 after the second sampling, comparing the pixel value set 1 at the first time and the pixel value set 2 at the second time to find that the two are inconsistent.
Then, in the continuous sampling process, the sampling time 10150ms and the pixel value set 2 obtained after the third sampling are obtained, and the pixel value set 2 obtained by the third sampling of the pixel value set 2 at the second time is compared, and the two are found to be consistent.
Since instability occurs during rendering, when the pixel value sets are consistent twice, it is further verified whether the subsequent pixel value is also the pixel value set 2 in order to ensure that the pixel value is not changed any more.
In the subsequent comparison process, the pixel value set of the preset pixel point set is found to be changed again, and the pixel value 3 is changed. The pixel value set 3 of the preset pixel point set is not changed; that is, when the pixel values of the consecutive preset times are consistent, it is determined that the pixel value set of the preset pixel point set does not change any more.
Step S205: and under the condition that the pixel value set of the preset pixel point set does not change any more, determining the first sampling time corresponding to the current pixel value set of the preset pixel point set as the page rendering completion time.
Continuing with the above example, the first sampling time 10200ms (fourth sampling time) of the pixel value 3 is taken as the page rendering completion time.
Step S206: and receiving a rendering ending instruction in the page rendering process, stopping sampling operation, and determining the page layout logic completion time as the page rendering completion time.
During the rendering process, some abnormal operation may occur to end the rendering process. For example, the user actively presses a "home key" to cause the application to switch home pages, the user actively presses an "power on" key to control screen blacking, and so on.
And stopping sampling operation after receiving a rendering ending instruction in the page rendering process. And determining the page layout logic completion time as the page rendering completion time because the preset pixel point set is still unstable.
Step S207: and calculating the time difference value between the page rendering completion time and the operation starting time.
Continuing with the above example, the page rendering completion time is 10200ms, and assuming that the obtained operation start time is 9900ms, the time difference between the two is 300 ms.
Step S208: and judging whether the time difference is within a preset time range, if so, entering the step S209, and if not, ending the step.
The technician sets the minimum time length and the maximum time length of the application starting time and the page switching time according to experience. The preset time range is composed of a minimum duration and a maximum duration.
The module determines whether the time difference is within a preset time range, and if so, it indicates that the time difference is valid (the terminal normally executes the operation process), and then the process goes to step S209. If not, the time difference is invalid (abnormality occurs in the terminal executing operation process).
Step S209: and determining the time difference value between the page rendering completion time and the operation starting time as the display time of the operation.
Through the technical means, the following beneficial effects can be realized:
according to the application, a new module is added in the application, and the module is used for calculating the time consumed by page switching and the time consumed by application starting, so that the intrusion code cannot be generated on the original module. In addition, the first sampling time when the pixel value set does not change is used as the page rendering completion time, and the application starting time and the page switching time which are obtained through calculation based on the page rendering completion time are closer to the real feeling of the user.
According to another embodiment provided by the present application, a second embodiment of a presentation time determination method is provided. The method is integrated in modules (namely new modules) outside original modules in the application of the IOS system. Referring to fig. 4, the method specifically includes the following steps:
step S401: an operation start time is acquired.
Step S402: and acquiring the completion time of the page layout logic.
Step S403: and in the page rendering process, sampling operation is carried out on a preset pixel point set, and sampling time and a pixel value set corresponding to the preset pixel point set are recorded. The pixel value set is described by taking table 1 as an example.
The above steps S401 to S403 can refer to the detailed description of steps S201 to S203, and are not described herein again.
Step S404: determining a variation of a set of neighboring pixel values of the set of preset pixel points.
Continuing with the above example, the variation is explained:
TABLE 2
Step S405: and under the condition that the variation of the pixel value set is less than or equal to the preset variation for multiple times, determining the first sampling time when the variation of the pixel value set is less than or equal to the preset variation as the page rendering completion time.
The precision in the above embodiment is higher, a preset variation may be set under the condition that the requirement for the rendering precision is not high, and the rendering of the page is determined to be completed under the condition that the variation of the pixel value set is less than or equal to the preset variation.
Continuing with the above example, assuming that the preset variation is 0.1, it can be found that the variation is 0 after the pixel value set is numbered 2, i.e. the variation is smaller than the preset variation. Therefore, the sampling time corresponding to the pixel value set corresponding to the sequence number 2 may be determined as the first sampling time, and the sampling time may be determined as the page rendering completion time.
Step S406: and receiving a rendering ending instruction in the page rendering process, stopping sampling operation, and determining the page layout logic completion time as the page rendering completion time.
Step S407: and calculating the time difference value between the page rendering completion time and the operation starting time.
Step S408: and judging whether the time difference is within a preset time range, if so, entering the step S409, and if not, ending.
Step S409: and determining the time difference value between the page rendering completion time and the operation starting time as the display time of the operation.
Through the technical means, the following beneficial effects can be realized:
according to the application, a new module is added in the application, and the module is used for calculating the time consumed by page switching and the time consumed by application starting, so that the intrusion code cannot be generated on the original module. In addition, the first sampling time when the pixel value set does not change is used as the page rendering completion time, and the application starting time and the page switching time which are obtained through calculation based on the page rendering completion time are closer to the real feeling of the user.
After the first embodiment and the second embodiment, the data volume of the operation corresponding page can be calculated; determining a page response speed corresponding to the operation based on the data volume and the display time; so that the page response speed can be invoked by a module that needs to use the page response speed.
In addition, in the page display process, the display time corresponding to each attribute can be respectively counted according to the attributes of the page content, for example, the display time of the character attribute, the display time of the picture attribute and the display time of the video attribute are counted; so that a module call is required that exposes the time using various attributes.
Of course, the presentation time of each attribute may also be output so that the user can view the presentation time of each attribute to determine whether the page performance is good.
