button - 在 AVPlayerLayer 顶部添加按钮 - iOS Swift

Question

我正在尝试在 AVPlayerLayer 顶部添加一个播放按钮，但它没有显示。

我有一个名为 playerView 的 UIView 作为 IBOutlet。

以下是我如何创建 player 和相应的 playerLayer，并将其放入 playerView 中:

    player = AVPlayer()
    superLayer = self.playerView.layer
    playerLayer = AVPlayerLayer(player: player)
    playerLayer.frame = self.playerView.bounds
    playerLayer.cornerRadius = 5.0
    playerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill
    superLayer.addSublayer(playerLayer)

    self.view.bringSubview(toFront: playVideoButton)

问题是 playVideoButton 没有显示在 playerLayer 之上(该按钮已添加到 Storyboard中)。我尝试隐藏 playerLayer 并且按钮仍然没有显示在下面，所以看起来按钮甚至不在 View 层次结构中。

也许这可以帮助

let player = AVPlayer(url: videoURL!)
let playerLayer = AVPlayerLayer(player: player)

let btn = UIButton()
btn.frame = CGRect(x: 23, y: 34, width: 25, height: 30)

playerLayer.addSublayer(btn.layer)
self.view.layer.addSublayer(playerLayer)
