Question

我的UIViewController我有UIView的电子插座，我希望使用外部链接显示视频。在这种情况下，我尝试创建AVPlayerLayer并将其添加到我的UIView商店。

我的代码看起来像这样：

class VievController: UICollectionViewController {
    @IBOutlet weak var playerView: UIView!

    override func viewDidLoad(){
            let playerItem = AVPlayerItem(URL: NSURL(string: ("https://www.youtube.com/watch?v=_yE_XgoWBso"))!)
            let avPlayer = AVPlayer(playerItem: playerItem)
            let playerLayer = AVPlayerLayer(player: avPlayer)
            playerLayer.frame = playerView.bounds
            playerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill
            playerView.layer.addSublayer(playerLayer)
            avPlayer.play()
    }
}//end class

我不知道为什么我在UIVIew插座上看不到视频 - 什么都没发生。你有什么建议我应该修理什么吗？

    let url = NSBundle.mainBundle().URLForResource("ding.mp3", withExtension: nil)
    guard let newURL = url else {
         print("Could not find file:")
        return
    }
    do {

        backgroundMusicPlayer = try AVAudioPlayer(contentsOfURL: newURL)
        backgroundMusicPlayer.numberOfLoops = 0
        backgroundMusicPlayer.prepareToPlay()
        backgroundMusicPlayer.play()

    } catch let error as NSError {
        //print(error.description)
    }

你需要导入avfoundation框架然后使用上面的代码

Below code help you to solve the issue

Adjust the frame according to your needs

- (void)viewDidLoad
{
   [super viewDidLoad];
   NSError *setCategoryError = nil;
  [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error: &setCategoryError];
  NSString *urlString=[NSString stringWithFormat:@"%@",@"http://www.youtube.com/watch?v=zPP6lXaL7KA&feature=youtube_gdata_player"];
  AVAsset *asset = [AVAsset assetWithURL:[NSURL urlWithString:urlString]];
  avPlayerItem = [[AVPlayerItem alloc]initWithAsset:asset];
  self.songPlayer = [AVPlayer playerWithPlayerItem:avPlayerItem];
  self.avPlayerLayer = [AVPlayerLayer playerLayerWithPlayer: self.songPlayer];
  self.avPlayerLayer.frame = self.view.layer.bounds;
  UIView *newView = [[UIView alloc] initWithFrame:self.view.bounds];
  [newView.layer addSublayer:avPlayerLayer];
  [self.view addSubview:newView];
  [ self.songPlayer play];
}

很遗憾，您无法使用AVPlayer播放YouTube，Vimeo等。为此，您必须使用UIWebView。
