尝试更改 UIwindowLevel ，也许在播放器级别上方会出现一个视图

         if let path = Bundle.main.path(forResource: "Timelapse Stabilizzata", ofType: "mov") {
                let video = AVPlayer(url: URL(fileURLWithPath: path))
                let videoPlayer = AVPlayerViewController()

                videoPlayer.view.window?.windowLevel = 0
                videoPlayer.player = video
                present(videoPlayer, animated: true, completion: {
                    video.play()
                })
}
