Referring to fig. 1, which is a schematic flowchart illustrating a picture loading method according to an embodiment of the present invention, as shown in fig. 1, the picture loading method may include:
step S101, when a user opens a webpage, judging whether a loading position of a picture to be loaded on the webpage is in a current display window of a terminal, and if the loading position is in the current display window, entering step S102; otherwise, the picture to be loaded at the loading position is not loaded.
Preferably, in this embodiment, the web page includes a plurality of pictures, each picture corresponds to a loading position, when the user opens the web page, first obtaining a loading position coordinate corresponding to each picture, then comparing the loading position coordinate corresponding to each picture with a coordinate of a current window displayed on a terminal foreground, and determining whether the loading position corresponding to each picture is within a display range of the current window, if so, entering step S102 to load the picture; otherwise, the picture corresponding to the position is not loaded. Therefore, only pictures needing to be displayed currently can be loaded, and pictures which are not in the display range are not loaded, so that the network flow consumption of the terminal is saved, and the fluency of webpage browsing is improved.
Step S102, inquiring whether the picture to be loaded exists in a terminal memory, and entering step S103 if the picture to be loaded exists in the memory; if the picture to be loaded does not exist in the memory, the process proceeds to step S104.
Preferably, in this embodiment, the memory of the terminal is equivalent to a buffer, and stores the picture in the form of key-value, when the terminal determines that the position to be loaded is within the current display window, the picture is first searched from the memory according to the URLKey of the loaded position, if the picture matching the URLKey of the loaded position is found, the process proceeds to step S103, otherwise, if the picture matching the URLKey of the loaded position is not found, the process proceeds to step S104.
Preferably, in this embodiment, some notifications may be registered, and when the memory is warned or the application is backed up to the background, the picture cached in the memory is cleaned, or when the application is ended, the expired picture cached in the memory is cleaned according to the time of the picture caching. The memory warning is a warning that the size of the cached picture in the memory exceeds a preset threshold value, namely the memory space is full.
And step S103, reading the picture to be loaded in the memory, and displaying the picture in the current window.
Preferably, in this embodiment, if the picture matched with the URLkey at the loading position is stored in the memory, the callback function is called to output the picture corresponding to the URLkey at the loading position to the web browsing interface of the current display window for display, so that the picture does not need to be downloaded from a hard disk or from a network, the consumption of network traffic is avoided, the picture loading speed is increased, and the web display is smoother.
Step S104, inquiring whether the picture to be loaded exists in a hardware cache of the terminal, and if the picture to be loaded exists in the hardware cache, entering step S105; otherwise, if the to-be-loaded picture does not exist in the hardware cache, the process proceeds to step S106.
Preferably, in this embodiment, if the picture matching the URLkey at the loading position is not stored in the memory, a sub-thread NSInvocationOperation is generated and added to a queue, and whether the picture to be loaded is stored is searched from a hardware cache of the terminal through the NSInvocationOperation operation, specifically: and attempting to read the picture file under a hardware cache directory according to the URLKEy of the loading position through NSoperation, and inquiring whether the picture to be loaded exists in the hardware cache. And the hardware is a hard disk in the terminal.
Step S105, reading the picture to be loaded from the hardware cache, and displaying the picture to be loaded on the current window.
Preferably, in this embodiment, if the picture to be loaded is queried in the hardware cache, the queried picture to be loaded is added to the memory of the terminal, and then the callback function is called to display the picture to be loaded in the current display window. In the process, if the memory is too small, the picture cached in the memory is cleared first, and the picture to be loaded is added to the memory.
And step S106, downloading the picture to be loaded from the network, and displaying the picture to be loaded on the current window.
Preferably, in this embodiment, if the to-be-loaded picture does not exist in both the memory and the hardware cache of the terminal, the to-be-loaded picture needs to be downloaded from the network, and at this time, the picture-calling-back loading function downloads the to-be-loaded picture from the network server according to the URL of the loading location. According to the embodiment of the invention, the picture to be loaded does not exist in the terminal memory and the hardware cache, and then the picture is downloaded from the network server, so that the consumption of terminal flow can be saved, and the picture loading speed is increased.
As can be seen from the above, in the image loading method provided by this embodiment, when the user opens the webpage, it is determined whether the loading position of the image to be loaded on the webpage is within the current display window of the terminal; if the current display window is in the current display window, inquiring whether the picture to be loaded exists in a terminal memory; if the picture to be loaded exists in the memory, reading the picture to be loaded in the memory, and displaying the picture in a current window; if the picture to be loaded does not exist in the memory, inquiring whether the picture to be loaded exists in a hardware cache of the terminal; if the picture to be loaded exists in the hardware cache, reading the picture to be loaded from the hardware cache, and displaying the picture to be loaded in the current window; if the picture to be loaded does not exist in the hardware cache, the picture to be loaded is downloaded from the network, and the picture to be loaded is displayed in the current window, so that the consumption of network flow can be saved, the fluency of webpage picture loading is improved, and the user experience is improved.
Fig. 2 is a flowchart illustrating a specific implementation of step S106 in the image loading method according to an embodiment of the present invention. Referring to fig. 2, in this embodiment, step S106 specifically includes:
step S201, sharing or regenerating a downloader, and downloading the picture to be loaded from the network server through the downloader;
step S202, if the picture to be loaded is downloaded, another sub thread decodes the picture to be loaded, and the picture to be loaded is decoded into a bitmap which can be directly used by a control displayed by the current window;
step S203, displaying the decoded picture to be loaded in the current window.
In this embodiment, the downloader downloads the picture to be loaded from the network server by using the NSURLConnection, and implements the related delete to determine the picture download state and call back the download data and the state to the loading module in the terminal. Wherein, the picture downloading state comprises: in download, download complete, and download failure.
In this embodiment, after determining that the data of the picture to be loaded is downloaded, the loading module in the terminal creates an nsaperationqueue sub-thread to decode the downloaded data corresponding to the picture to be loaded, so as to decode the picture to be loaded into a bitmap which can be directly used by the control, and after the decoding is completed, the bitmap is called back to the loading module, and the picture is called back to a required place in the main thread to be displayed. Because the data decoding is carried out in the newly-built sub thread instead of the main thread, the main thread is not dragged, and the loading speed of the picture is further improved.
In addition, it should be noted that, if the picture to be loaded downloaded from the network can be directly used by the control, it is not necessary to decode the picture, and the picture is directly called back to the loading module of the terminal.
Preferably, in this embodiment, after step S203, the method may further include:
and storing the decoded picture to be loaded into the memory and the hard disk cache.
Preferably, in this embodiment, the decoded picture to be loaded may be written into the memory and the hard disk of the terminal by another sub-thread nsinvocalization operation, so that the slow-down of the main thread may be avoided.
In the embodiment, after the picture to be loaded is downloaded from the network server, the picture to be loaded is decoded, and the decoded picture is written into the memory and the hard disk of the terminal, so that the picture to be loaded can be directly loaded from the memory or the hard disk when the webpage is opened next time without downloading from the network server again, thereby not only saving the consumption of terminal flow, but also improving the loading speed of the picture and promoting the fluency of a user for browsing the webpage picture.
Fig. 3 is a schematic flowchart of a picture loading method according to an embodiment of the present invention. Referring to fig. 3, in comparison with the embodiment shown in fig. 1, the method for loading a picture provided in this embodiment further includes:
step S301, setting an occupation map for the loading position of the picture to be loaded on the webpage in advance, wherein the occupation map is a self-defined picture or a blank.
Preferably, in this embodiment, a user can set a placeholder map of a loading position corresponding to a picture to be loaded on a webpage by a user-defined method, and can also set the placeholder map to be empty. Specifically, when the user opens the webpage, the image loading position on the webpage is judged, and if the image loading position is not in the current display window of the terminal, the image corresponding to the position is not loaded, and the position is blank, or a user-defined occupation map preset for the position is loaded to the corresponding position. Therefore, the browsing experience of the user can be further improved.
It should be noted that, in this embodiment, the implementation manners of step S302 to step S307 are the same as the implementation manners of step S101 to step S106, and therefore, the detailed description thereof is omitted.
As can be seen from the above, the picture loading method provided by the embodiment can also save the consumption of network traffic and improve the fluency of webpage picture loading; in addition, compared with the previous embodiment, the page browsing experience of the user can be further improved.
