Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The method for displaying the webpage view provided by the application can be applied to the terminal 100 shown in fig. 1. The terminal 100 is loaded with an operating system 101 and an application program 102, when the application program 102 controls to display a page, a rendering process of a web page view is correspondingly generated, and if the memory of the operating system is insufficient and the rendering process of the web page view is terminated, the application program 102 loaded in the terminal 102 executes the method for displaying a web page view according to the embodiment of the present application, and resumes to display the terminated page. The terminal 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, portable wearable devices, and the like.
In an embodiment, as shown in fig. 2, a method for displaying a web page view is provided, which is described by way of example when the method is applied to an application program loaded on a terminal in fig. 1, and includes the following steps:
s202, receiving a notice that the rendering process of the webpage view is terminated;
in this step, the application program monitors the rendering process state of the current web view, and when the operating system terminates the rendering process of the web view, the application program receives a notification that the rendering process of the web view is terminated. In particular, a notification that a rendering process of a web page view is terminated may be monitored and received while an application is active, while an existing partial operating system may not be able to receive a notification that a rendering process of a web page view is terminated if the application is not active.
By way of example, taking an operating system as an Ios system as an example, the corresponding web page view is wkbwebview. In this step, the application program may monitor whether the operating system terminates (Kill) the rendering process of WKWebView through WebViewWebContentProcessDidTerminate. Specifically, whether the rendering process of the wkpeview is terminated by the operating system can be determined by determining whether the wkpeview.
S204, detecting the display state of the current webpage view; wherein the display state comprises a display state or a non-display state; if the current webpage view is in the non-display state, executing S206;
in this step, after receiving the notification that the rendering process of the web page view is terminated, the application program detects the display state of the currently terminated web page view. If the rendering process of the current webpage view is not terminated, the loaded page corresponding to the webpage view can be seen by the user, and the current webpage view is in the displaying state, and if the rendering process of the current webpage view is not terminated, the loaded page corresponding to the webpage view cannot be seen by the user, for example, under the conditions of background hiding of a program and the like, the current webpage view is in the non-displaying state.
S206, when the current webpage view is switched to the displaying state, the webpage view is reloaded.
In this step, if the current web page view is in the non-display state, the application program does not immediately reload the web page view, but can record that the current web page view needs reloading, and reload the web page view when waiting for monitoring that the current web page view is switched from the non-display state to the display state.
According to the webpage view display method, when the notification that the rendering process of the webpage view is terminated is received, the display state of the current webpage view is detected, if the current webpage view is detected to be in the non-display state, the webpage view does not need to be reloaded immediately, and the webpage view is reloaded when the current webpage view is switched to the display state. Therefore, the condition of reloading failure or slow operation system operation efficiency caused by immediately reloading the webpage view after the rendering process of the webpage view is just terminated can be reduced, the consumption of a memory is reduced, and the reloading efficiency of the webpage view is improved.
In one embodiment, as shown in fig. 3, after detecting the display state of the current web page view, the method further includes: if the current webpage view is in the displaying state, executing S208;
and S208, reloading the webpage view.
In this embodiment, when a notification that the rendering process of the web page view is terminated is received, if the current web page view is in the displaying state, it is described that if the web page view is not reloaded in time at this time, a situation that the page display is blank occurs, the web page view is directly reloaded, so as to recover the display content of the web page as soon as possible, and reduce the situation that the page is blank.
In one embodiment, if the current web page view is in the non-display state, executing S206, and waiting until the current web page view is switched to the display state, reloading the web page view, including: if the current webpage view is in an undisplayed state, assigning the reloading flag quantity to be a first value; when the situation that the webpage view is switched to the displaying state is monitored, reading the value of the reloading mark quantity; and if the reloading mark quantity value is read to be the first value, reloading the webpage view, and assigning the reloading mark quantity value to be the second value.
For example, the reload flag may be a Boolean (BOOL) variable, when the value of the variable is true, the rendering process representing the web page view is closed by the operating system, and the display page of the web page view needs to be reloaded the next time the web page view switches to the displaying state. When the variable is assigned to false, the web page view is switched to the displaying state without reloading the display page of the web page view.
In this embodiment, each time the terminal receives a notification that the web page view is terminated and the web page view is in an undisplayed state, the terminal assigns a reload flag to a first value to record that the currently terminated web page view needs to be reloaded. In this way, when the terminal monitors that the webpage view is switched from the non-display state to the display state every time, the operation of reading the reloading mark amount is executed once, and if the read reloading mark amount is a first value, the webpage view which is being displayed is reloaded; and if the read reloading flag quantity is a second value, the process of rendering the webpage view is not terminated at the moment, and the webpage view which is being displayed does not need to be reloaded. Therefore, efficient recording of whether the webpage needs to be reloaded is achieved, memory occupation caused by reloading of the webpage view under unnecessary conditions is avoided, and operation efficiency is improved.
In one embodiment, detecting a display state of a current web page view includes: detecting whether an application program corresponding to the current webpage view is in an active state; detecting whether a view controller currently containing a webpage view is positioned at the top of a view controller stack; if the current application program is in an active state and the current view controller is positioned at the top of the view controller stack, determining that the current webpage view is in a displaying state; if the current application is not in an active state or the current view controller is not at the top of the view controller stack, then it is determined that the current web page view is in an undisplayed state.
The active state of the application program may include two types, one is in an active state, for example, the application program is in the process of being started and used by a user; the other is not in an active state, for example, when the user presses the home key of the terminal, or receives a call, turns on the control center, or the like. If the application is detected not to be in the active state, it may be determined that the web page view of the application is in the non-displayed state at that time, and if the application is in the active state, further determination may be required based on the position of the view controller containing the web page view in the view controller stack.
For example, for an Ios operating system, it may be determined that a current application is in an active state when [ uiapplicationshared application ]. applicationState ═ uiapplicationstate active is detected. And may determine that the view controller currently containing the web page view is located at the top of the view controller stack when a self.
In this embodiment, the display state of the current web page view can be determined quickly and accurately according to the active state of the web page view and the position of the view controller containing the web page view in the view controller stack.
In one embodiment, the switching of the current web page view to the displaying state includes: when the application program corresponding to the current webpage view is not in an active state, monitoring the active state of the application program; if the situation that the application program is switched from the inactive state to the active state is monitored, whether a view controller containing the webpage view is located at the top of a view controller stack or not is detected; and if the current view controller is positioned at the top of the view controller stack, determining that the current webpage view is switched to the displaying state.
Taking the Ios operating system as an example, when it is monitored that the uiapplicationdigbecomeactivenotification is notified that the application program returns from the inactive state to the active state, it may be determined that the application program is switched from the inactive state to the active state.
In this embodiment, when the application program corresponding to the current web view is not in the active state and it is to be monitored that the application program is switched to the active state, it is determined that the current web view is switched to the displaying state when the view controller currently including the web view is located at the top of the view controller stack. Therefore, the current webpage view can be quickly and accurately determined to be switched to the displaying state.
In one embodiment, the switching of the current web page view to the displaying state includes: when the application program corresponding to the current webpage view is in an active state and the view controller containing the webpage view is not positioned at the top of the view controller stack, when the view controller of the webpage view is monitored to be positioned at the top of the view controller stack, the webpage view is determined to be switched to a displaying state.
Taking the Ios operating system as an example, when an application program corresponding to a web page view is in an active state, and when a user operates to enable a view controller containing the web page view to reach the top of a view controller stack, responding to the life cycle of the view controller: - (void) viewDidAppear (BOOL) animated, the web page view may be switched to the displaying state.
In this embodiment, when the application corresponding to the current web page view is in an active state, it is determined that the web page view is switched to the displaying state when the view controller of the web page view is located at the top of the view controller stack. Therefore, the current webpage view can be quickly and accurately determined to be switched to the displaying state.
In one embodiment, reloading the web page view comprises: removing the webpage view with the rendering process terminated from a view controller containing the webpage view; constructing a new webpage view in the memory, and adding the new webpage view into the view controller; and loading and displaying the new webpage view by using the view controller containing the new webpage view. Wherein the constructed new webpage view corresponds to the same display page as the terminated webpage view.
For example, in the Ios operating system, the new web page view may be displayed according to url load [ WKWebView loadRequest ] load.
When the webpage view is reloaded, an alternative scheme is to Reload the terminated webpage view, for example, in an Ios system, the terminated webpage view can be reloaded by calling a Reload method of wkbwebview. In the embodiment, the terminated webpage view is not loaded, but the terminated webpage view is completely removed, and a new webpage view is constructed and loaded, so that memory leakage can be avoided, and the success rate of reloading is improved.
It should be understood that although the various steps in the flow charts of fig. 2-3 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
