MPMoviePlayerController 已弃用，现在怎么办？

Question

所以当 MPMoviePlayerController 被弃用时，我一直在寻找解决方案。我当前的代码工作正常：

moviePlayer = MPMoviePlayerController(contentURL: receivedURL)
    moviePlayer!.movieSourceType = MPMovieSourceType.Unknown
    moviePlayer!.view.frame = view.bounds
    moviePlayer!.scalingMode = MPMovieScalingMode.AspectFill
    moviePlayer!.controlStyle = MPMovieControlStyle.None
    moviePlayer!.shouldAutoplay = true

    view.addSubview((moviePlayer?.view)!)
    moviePlayer?.setFullscreen(true, animated: true)
    moviePlayer!.play()

我录制了一个视频，录制完成后，它将在新视图中使用上面的代码播放。但据我了解 MPMoviePlayerController 在 iOS9 中已弃用，我找不到任何像上面的代码一样工作的解决方案。我知道我需要用户 AVPlayer 和 AVPlayerViewController。

我已经尝试过this 和许多其他看起来像它们的解决方案。 但它不会像我在上面的代码中想要的那样工作。

我只想录制一段视频，并在新视图中播放，就像 snapchat 一样。

请帮帮我

添加的附加信息：

因此，当我尝试使用this（已接受的答案）或this solution（AVPlayer）修复它时，视图为空白。什么都没有显示。

var player:AVPlayer!
    let avPlayerLayer:AVPlayerLayer = AVPlayerLayer(player: player)
    avPlayerLayer.frame = CGRectMake(50,50,100,100)
    self.view.layer.addSublayer(avPlayerLayer)
    player = AVPlayer(URL: receivedURL)
    player.play()

如果我尝试使用我必须修改的AVPlayerViewController：

let player = AVPlayer(URL: receivedURL)
    let playerViewController = AVPlayerViewController()
    playerViewController.player = player
    dispatch_async(dispatch_get_main_queue(), {
        self.presentViewController(playerViewController, animated: true) {
            playerViewController.player?.play()
        }
    })

发生这种情况，没有显示任何内容。

Answer 1

var player:AVPlayer!
let avPlayerLayer:AVPlayerLayer = AVPlayerLayer(player: player)
avPlayerLayer.frame = CGRect(x:50,y:50,width:100,height:100)
self.view.layer.addSublayer(avPlayerLayer)
player = AVPlayer(url: receivedURL)
player.play()

在这里，您将播放器添加到 AVPlayerLayer 后对其进行初始化。试试这样：

let player = AVPlayer(url: receivedURL)
let avPlayerLayer:AVPlayerLayer = AVPlayerLayer(player: player)
avPlayerLayer.frame = CGRect(x:50,y:50,width:100,height:100)
self.view.layer.addSublayer(avPlayerLayer)
player.play()
