AVPlayerViewController不播放本地video

我在我的项目中添加了一个DemoVideo.mp4，并将其添加到复制资源文件。 但是，当我运行该应用程序，它不会播放我的video。 这是我的方法。

private func setUpAndPlayVideo() { guard let videoPath = Bundle.main.path(forResource: "DemoVideo.mp4", ofType: nil) else { return } let videoURL = NSURL(string: videoPath) let player = AVPlayer(url: videoURL! as URL) playerViewController = AVPlayerViewController() playerViewController.player = player playerViewController.view.frame = self.videoPlayerView.bounds self.videoPlayerView.addSubview(playerViewController.view) playerViewController.showsPlaybackControls = false playerViewController.player?.play() } 

我在viewDidAppear方法中调用此方法，但它显示此。

  let path : String = Bundle.main.path(forResource: "charlie", ofType: "mp4")! let movieurl : URL = URL(fileURLWithPath: path) let movie : AVPlayerViewController = AVPlayerViewController() movie.view.frame = self.view.bounds let player : AVPlayer = AVPlayer(url: movieurl) movie.player = player self.view.addSubview(movie.view) player.play()
