iOS:外部显示器 AVPlayerController 关闭问题

Question

我遇到了与此问题相同的问题，但我不知道我错在哪里。

它仍然保留在外部显示器上视频的最后一帧。

iOS Swift App AVPlayerController dismiss not working on external display

不幸的是，我没有足够的声誉点来评论其他问题。

是因为我没有AVPlayerItem吗？

let fourVideoViewController = AVPlayerViewController()    

@IBAction func fourVideoPlayButton(_ sender: Any) {

    let fourVideoURL = Bundle.main.url(forResource: "Four Animation", 
withExtension: "mov")!
    let fourPlayer = AVPlayer(url: fourVideoURL as URL)

    fourVideoViewController.player = fourPlayer

    NotificationCenter.default.addObserver(self, selector: 
#selector(playerDidFinishPlaying), name: 
NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: 
fourVideoViewController.player?.currentItem)

    self.present(fourVideoViewController, animated: true) {
        self.fourVideoViewController.player!.play()
    }
}


@objc func playerDidFinishPlaying(note: NSNotification) {

    fourVideoViewController.dismiss(animated: true, completion: nil)
    fourVideoViewController.view.removeFromSuperview()
    self.presentedViewController?.dismiss(animated: true, completion: nil)
}

Answer 1

您可以尝试在 playerDidFinishPlaying 函数中关闭

self.navigationController?.popToRootViewController(animated: true)

或者

self.view.window!.rootViewController?.dismiss(动画:true，完成:nil)
