视图内的AVPlayerViewController未显示播放控件

问题描述

我正在和苹果电视一起工作.我的UIViewController中有一个UIView.我将AVPlayerViewController添加为UIView的子视图. UIView的框架为CGRect(x:50，y:50，宽度:1344，高度:756).我将AVPlayerViewController框架设置为等于UIView框架.

I am working with apple tv. I have a UIView inside my UIViewController. I am adding AVPlayerViewController as subview of my UIView. UIView's frame is CGRect(x: 50, y: 50, width: 1344, height: 756). I am setting AVPlayerViewController frame equals to my UIView's frame.

问题是视频在其帧中播放正常，但是诸如暂停，播放，前进等控件被隐藏并且无法正常工作.但是，当我将frame设置为CGRect(x:0，y:0，width:1920，height:1080)时，控件是可见的并且可以正常工作.

我的代码如下:

    let url = URL(string: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")
    let item = AVPlayerItem(url: url!)
    self.player = AVPlayer(playerItem: item)
    self.avplayerController = AVPlayerViewController()
    self.avplayerController.player = self.player
    self.avplayerController.view.frame = videoPreviewLayer.frame
    self.avplayerController.showsPlaybackControls = true
    self.avplayerController.requiresLinearPlayback = true

    self.addChildViewController(self.avplayerController)
    self.view.addSubview(self.avplayerController.view)

    self.avpController.player?.play()

请帮助.
