Question

我有一个父视图，其中包含一个实例化AVPlayerViewController对象的播放按钮。如果用户按下播放器的默认“完成”按钮，则播放器视图将消失，父视图将按预期工作。但是，当播放到达视频结尾时，播放器消失，但父视图屏幕对按钮点击无响应。我不明白，因为两个场景都使用相同的回调来关闭玩家视图。

以下是我实例化AVPlayer的代码，并设置了两个有关如何完成播放的通知：

func playVideoLocally() {
    // create player
    let playerItem = AVPlayerItem(asset: AVAsset(URL: NSURL(string: media.url)!))
    player = AVPlayer(playerItem: playerItem)

    // create modal view with callback for done button
    // This works fine
    playerController = CustomAVPlayerViewController()
    playerController.player = player
    playerController.modalPresentationStyle = UIModalPresentationStyle.OverFullScreen
    NSNotificationCenter.defaultCenter().addObserver(self,
        selector: "onLocalPlayCompletion:",
        name: CustomAVPlayerViewController.viewWillDisappearNotification,
        object: nil)
    self.presentViewController(playerController, animated: true, completion: nil)

    // create player completion callback
    // This leads to unresponsive parent view
    NSNotificationCenter.defaultCenter().addObserver(self, selector: "onLocalPlayCompletion:",
        name: AVPlayerItemDidPlayToEndTimeNotification,
        object: playerItem)

    // play it
    player.play()
}

这是两个场景都在调用的onLocalPlayCompletion回调：

func onLocalPlayCompletion(note: NSNotification) -> Void {
    playerController.view.removeFromSuperview()
    onCompletion()
}

Answer 1

我发现了问题。按下＆＃34;完成＆＃34;的唯一原因没有影响父视图是因为它使用默认的AVPlayer动作来解雇自己。我试图从内部onLocalPlayCompletion（），

中解雇玩家

playerController.view.removeFromSuperview()

不正确，在我的情况下，我用

替换它

self.dismissViewControllerAnimated(true, completion: nil)

做我想要的。

在AVPlayerViewController被解雇后查看无响应 - Swift
