当视频从所有屏幕完成时自动关闭 AVPlayer

Question

当我的视频完成后，我希望它拉下 AVPlayer 并返回到主视图控制器。

我还想在连接时从我的外部屏幕/显示器下拉视频。

我该怎么做？

我在这里尝试了几个不同的答案，但到目前为止都没有奏效。

注意：四是我视频的名称

@IBAction func fourVideoPlayButton(_ sender: Any) {

    if let path = Bundle.main.path(forResource: "Four", ofType: "mp4") {

        let fourVideo = AVPlayer(url: URL(fileURLWithPath: path))
        let fourVideoPlayer = AVPlayerViewController()
        fourVideoPlayer.player = fourVideo

        present(fourVideoPlayer, animated: true, completion: {
            fourVideo.play()
        })
    }
}

Answer 1

你需要添加观察者来检测玩家何时结束播放

NotificationCenter.default.addObserver(self, selector: Selector(("playerDidFinishPlaying:")), 
       name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: fourVideoPlayer.player.currentItem)

func playerDidFinishPlaying(note: NSNotification) {
    fourVideoPlayer.dismiss(animated: true, completion: nil)
}

希望对您有所帮助！

在 Swift 4.2 中，

let fourPlayerController = AVPlayerViewController()

    @IBAction func fourVideoPlayButton(_ sender: Any) {
        guard let path = Bundle.main.path(forResource: "Four", ofType:"mp4") else {
            return
        }
        let fourVideoPlayer = AVPlayer(url: URL(fileURLWithPath: path))
        fourPlayerController.player = fourVideoPlayer
        NotificationCenter.default.addObserver(self, selector: #selector(playerDidFinishPlaying), name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: fourPlayerController.player?.currentItem)

        present(fourPlayerController, animated: true) {
            fourVideoPlayer.play()
        }
    }

    @objc func playerDidFinishPlaying(note: NSNotification) {
        fourPlayerController.dismiss(animated: true, completion: nil)
        fourPlayerController.dismiss(true, completion: nil)
        fourPlayerController.view.removeFromSuperview()
        self.presentedViewController?. dismiss(true, completion: nil)
    }
