【问题描述】：

在按钮的@IBAction 中使用此代码会打开视频播放器，但它只显示黑屏。我不知道为什么。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()
        )

【问题讨论】：

控制台是否出现任何错误？

【参考方案1】：

尝试改变UIwindowLevel，也许玩家层级上方出现了一个视图

         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()
                )

它不会改变任何东西:(
