Question

这是我的代码，如何将此AVPlayerViewController添加到AVPlayerLayer，以及如果我们点击hideButton如何隐藏该图层。

NSString *videoFilePath = [[NSBundle mainBundle]pathForResource:self.string ofType:@"mp3"];
self.avPlayer = [[AVPlayer alloc]initWithURL:[NSURL fileURLWithPath:videoFilePath]];
self.avPlayerViewController = [[AVPlayerViewController alloc]init];
self.avPlayerViewController.view.frame = CGRectMake(25,375,250,300);
self.avPlayerViewController.player = self.avPlayer;
[self.view addSubview:self.avPlayerViewController.view];
[self.avPlayerViewController.player play];

如果你想在图层中播放视频，则不需要添加AVPlayerController。

代码如下：

在开始时声明这个2变量：

AVPlayer *player;
AVPlayerLayer *playerLayer;

添加以下方法，并在viewDidLoad

调用它

-(void)setUpVideoPlayer
{
    AVAudioSession *audioSession = [AVAudioSession sharedInstance];
    NSError *aErr;
    [audioSession setCategory:AVAudioSessionCategoryAmbient withOptions:AVAudioSessionCategoryOptionMixWithOthers error:&aErr];

    NSString *videoFilePath = [[NSBundle mainBundle] pathForResource:@"videoFileName" ofType:@"videoFileType"];
    NSURL *fileURL = [NSURL fileURLWithPath:videoFilePath];
    player = [AVPlayer playerWithURL:fileURL];
    playerLayer = [AVPlayerLayer playerLayerWithPlayer:player];
    [playerLayer setVideoGravity:AVLayerVideoGravityResizeAspectFill];
    playerLayer.frame = // Set Frame whichever you want;

    [self.videoView.layer addSublayer:playerLayer];

    [player seekToTime:kCMTimeZero];
    [player setVolume:0.0f];
    [player setActionAtItemEnd:AVPlayerActionAtItemEndNone];

    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(playerItemDidReachEnd:)
                                                 name:AVPlayerItemDidPlayToEndTimeNotification
                                               object:[player currentItem]];
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(playerStartPlaying)
                                                 name:UIApplicationDidBecomeActiveNotification object:nil];
}

-(void)playerStartPlaying
{
    [player play];
}

-(void)playerItemDidReachEnd:(NSNotification*)notification
{
    AVPlayerItem *p = [notification object];
    [p seekToTime:kCMTimeZero]; // Play it again when video ends
}

每当您想要开始播放视频时，请调用此方法：[player play]，只要您想隐藏图层，只需隐藏播放器图层并调用[player pause]即可停止播放视频的播放器。
