在iOS 8中如何在UIWebView Player中接收全屏模式的通知？

Posted 2021-04-06

在UIWebView中以全屏模式播放视频后，我想做一些事情。所以，我希望来自UIWebView的消息进入全屏并从全屏退出。

在ios 7中，我收到以下内容的通知：

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(VideoEnterFullScreenHere:)
                                             name:@"UIMoviePlayerControllerDidEnterFullscreenNotification"
                                           object:self.view.window];

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(VideoExitFullScreenHere:)
                                             name:@"UIMoviePlayerControllerDidExitFullscreenNotification"
                                           object:self.view.window];

但是在iOS 8中，它无法正常工作。

答案

以下内容对我有用。我希望它会帮助别人！

在AppDelegate.m类中，

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(windowBecameHidden:) name:UIWindowDidBecomeVisibleNotification object:nil];

    return YES;
}

并接受它，

- (void)windowBecameHidden:(NSNotification *)notification {

    UIWindow *window = notification.object;

    if (window != self.window) {
        NSLog(@"Online video on full screen.");
    }
}

谢谢！

另一答案

使用AVPlayer通知而不是UIMoviePlayer通知。

[[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(playerItemInitiated:)
                                                 name:@"AVPlayerItemBecameCurrentNotification"
                                               object:nil];
