AVPlayer层有时不显示视频内容-Java 学习之路

AVPlayer层有时不显示视频内容但播放音频 . 这种情况有时会发生，而不是每次都是我的代码行：

override func viewDidLoad() {
        super.viewDidLoad()
        self.tempVideoPath = NSURL(fileURLWithPath: NSTemporaryDirectory()).appendingPathComponent("tmpMov.mov")
        self.player = AVPlayer(url: self.tempVideoPath!)
}

 override func viewDidAppear(_ animated: Bool) {
     super.viewDidAppear(animated)
     self.playerLayer = AVPlayerLayer(player: self.player)
     self.playerLayer?.frame = self.videoPlayer.bounds
     self.playerLayer?.backgroundColor = UIColor.yellow.cgColor
     self.videoPlayer.layer.addSublayer(playerLayer!)
     print("player = \(playerLayer?.bounds)")

 }

帮我解决这个问题 .

你的代码问题是videoPlayer的界限可以改变 . 因此，您需要将以下代码添加到视图控制器，以相应地更改AVPlayerLayer的框架：
```
override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()

    playerLayer?.frame = view.bounds
}
```
希望能帮助到你 .
