ios - 使用 AVPlayer 黑屏(在模拟器和设备中)

Question

在按钮的 @IBAction 中使用此代码，视频播放器会打开，但仅显示黑屏。我不明白为什么。谢谢

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


        videoPlayer.player = video

        present(videoPlayer, animated: true, completion: {
            video.play()
        })

尝试改变UIwindowLevel，也许玩家等级上方会出现一个 View

         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()
                })
}
