AVPlayerViewController不播放本地视频

Question

我在项目中添加了DemoVideo.mp4并将其添加到复制资源文件中。但是，当我运行应用程序时，它不播放我的视频。 这是我的方法。

SELECT TABLE_NAME, COLUMN_NAME 
  FROM information_schema.COLUMNS
 WHERE TABLE_SCHEMA=DATABASE()
   AND DATA_TYPE IN ('char', 'varchar', 'text')

我在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() } 方法中调用此方法，但它显示了这个。

Answer 1

 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()
