推荐答案

为了处理网络变化，你必须为添加观察者AVPlayerItemFailedToPlayToEndTimeNotification 。

In order to handle network changes, you have to add an observer for AVPlayerItemFailedToPlayToEndTimeNotification.

- (void) playURL:(NSURL *)url
{
    AVPlayerItem *playerItem = [AVPlayerItem playerItemWithURL:url];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playerItemFailedToPlayToEndTime:) name:AVPlayerItemFailedToPlayToEndTimeNotification object:playerItem];
    self.player = [AVPlayer playerWithPlayerItem:playerItem];
    [self.player play];
}

- (void) playerItemFailedToPlayToEndTime:(NSNotification *)notification
{
    NSError *error = notification.userInfo[AVPlayerItemFailedToPlayToEndTimeErrorKey];
    // Handle error ...
}
