Question

我有一个按需播放视频片段的应用。这在以前版本的Xcode中运行良好，但我已升级到8.3.3并且遇到AVPlayerViewController问题。

视频正常播放和显示。控制栏出现在视图的底部，但不响应点击，一旦淡出，在点击视频时不再出现 - 除非，即我点击视图的左上角附近。

我的猜测是，实际的控件隐藏在某种覆盖层中，这种覆盖层的大小不正确，即它没有正确覆盖整个视频视图。有没有办法强制AVPlayerViewController重新布局？

我尝试添加：

    _playerController!.view.setNeedsLayout()
    _playerController!.view.layoutIfNeeded()

但这没有效果。

这是我的代码：

override func viewDidLoad() {

    super.viewDidLoad()

    _player = AVPlayer()
    _playerController = AVPlayerViewController()
    _playerController!.showsPlaybackControls = true
    _playerController!.allowsPictureInPicturePlayback = false
    _playerController!.videoGravity = AVLayerVideoGravityResizeAspectFill
    _playerController!.player = _player
    self.addChildViewController(_playerController!)
    videoView.addSubview(_playerController!.view)
...

override func viewDidLayoutSubviews() {

    let frame = UIScreen.main.bounds        
    _vidWidth = frame.width - 256.0
    _vidHeight = _vidWidth / 854.0 * 480.0

    videoView.frame = CGRect(x: 0, y: 10.0, width: _vidWidth, height: _vidHeight)
    videoView.backgroundColor = UIColor.black

    _playerController?.view.frame = CGRect(x: 0, y: 0, width: _vidWidth, height: _vidHeight)
...

func playVideo(_ clip: Clip) {

    var videoUrl: URL? = nil

    if  clip.offlineLocation != nil && clip.state == 2 {
        _videoPath = clip.offlineLocation!
        videoUrl = URL(fileURLWithPath: _videoPath!)
    }
    else {
        _videoPath = "https://xxxx.cloudfront.net/" + clip.location
        videoUrl = URL(string: _videoPath!)
    }

    NSLog(_videoPath!)

    let asset = AVURLAsset(url:videoUrl!, options:nil)
    let playerItem = AVPlayerItem(asset: asset)

    _player!.replaceCurrentItem(with: playerItem)
    _player!.play()
}

AVPlayerViewController控件无法正常工作
