UIViewController覆盖播放视频按钮

Question

let player = AVPlayer(url: URL(fileURLWithPath: path))
playerViewController.player = player
playerViewController.showsPlaybackControls = true
playerViewController.allowsPictureInPicturePlayback = false                                    
self.present(playerViewController, animated: false)

这很好。问题是视频很短，控制器需要几秒钟才能消失。我希望控制器在单击播放按钮时立即消失。是否有延迟设置，还是我必须使用NotificationCenter创建一个覆盖播放视频按钮的功能，该功能将包括playerViewController.showsPlaybackControls = false？我该如何在Swift 4中编写代码
