WKWebView媒体播放器全屏检测

Question

在iOS 8之前,UIMoviePlayerControllerDidEnterFullscreenNotification只要媒体播放器从UIWebView进入全屏,就会发送通知.在iOS 8中,这不会发生,有些人建议收听AVPlayerItemBecameCurrentNotification通知.这似乎不是从WKWebView发送的.收听UIWindowDidBecomeVisibleNotification通知无效,因为已针对所有添加的窗口(包括广告网络等内容)触发

最重要的是,我整晚都在努力,我似乎​​无法弄清楚如何使用WKWebView全屏打开视频.任何帮助,将不胜感激.

编辑:为了确认,我创建了一个空白项目.添加了一个UIWebView和AVPlayerItemBecameCurrentNotification它的监听器,当我播放视频并且它进入全屏时它被触发.我将UIWebView切换到WKWebView,并且不再触发该通知.

此解决方法似乎适用于 iOS8 和 iPhone 6

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    ...

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

    return TRUE;
}

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

    UIWindow *window = notification.object;

    if (window != self.window) {    // Not my own window: assuming the video window was hidden, maybe add some more checks here.

            // Add code here
    }
}
