Ios 重用AVPlayer实例播放视频的问题

我将在两个屏幕上播放相同的视频，并保持搜索时间。因此，我在这些屏幕中重用

AVPlayer

实例。这是第一次

AVPlayer

工作正常，但只要重复使用，播放器的框架就会从左上角开始动画，以适应开始播放时的目标视图

像，

代码看起来像

    if myObj._playerResult != nil {
        _player = myObj._playerResult //reuse player instance
    } else {
        // First create an AVPlayerItem
        let playerItem : AVPlayerItem = AVPlayerItem(URL: NSURL(string:sVideoUrl as String))
        _player = AVPlayer(playerItem: playerItem)
    }

    playerController = AVPlayerViewController()
    playerController?.showsPlaybackControls = false
    playerController?.player = _player
    playerController!.view.frame = targetView.bounds 
    targetView.addSubview(playerController!.view)       
    _player?.play()
