Question

我有一个AVPlayer，只要点击链接，我就会加载到新视图中。

-(void)createAndConfigurePlayerWithURL:(NSURL *)movieURL sourceType:(MPMovieSourceType)sourceType {
self.playerItem = [AVPlayerItem playerItemWithURL:movieURL];
customControlOverlay = [[AFDetailViewController alloc] initWithNibName:@"AFMovieScrubControl" bundle:nil];
backgroundWindow = [[UIApplication sharedApplication] keyWindow];
[customControlOverlay.view setFrame:backgroundWindow.frame];
[backgroundWindow addSubview:customControlOverlay.view];

playerLayer = [AVPlayerLayer playerLayerWithPlayer:[AVPlayer playerWithPlayerItem:playerItem]];
[playerLayer.player play];
playerLayer.frame = customControlOverlay.view.frame;
[customControlOverlay.view.layer addSublayer:playerLayer]; 
}

上面的代码将AVPlayer添加到我的应用程序并正常工作。我的customControlOverlay笔尖中有一个切换，应该删除视图并停止播放AVplayer。

-(IBAction)toggleQuality:(id)sender {
if (qualityToggle.selectedSegmentIndex == 0) {
    NSLog(@"HD");
    [playerLayer.player pause];
    [self.view removeFromSuperview];

} else if (qualityToggle.selectedSegmentIndex == 1) {
    NSLog(@"SD");
}
}

视图已正确删除，但播放器仍在后台播放。经过测试后，玩家不会对toggleQuality方法中的任何代码做出响应，但是我在那里的字符串会被记录。

对我做错了什么的想法？

Answer 1

我知道这是一个老问题，但有一天它可能对某人有所帮助。

由于 playerLayer 被添加为sublayer而不是subview，因此只需将其从其超级层（而非超级视图）和播放器中删除应该设置为nil，例如：

/* not sure if the pause/remove order would matter */
[playerLayer.player pause];
// uncomment if the player not needed anymore
// playerLayer.player = nil;
[playerLayer removeFromSuperlayer];

Answer 2

以下是Swift的答案。

就像@Paresh Navadiya和@Yoga在下面的评论中所说的那样。 playerLayer的玩家必须设置为零。 playerLayer?.player = nil

在viewWillDisappear中添加代码：

override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)

        player?.pause() // 1. pause the player to stop it
        playerLayer?.player = nil // 2. set the playerLayer's player to nil
        playerLayer?.removeFromSuperlayer() // 3 remove the playerLayer from it's superLayer
}

无法删除或停止AVPlayer
