我正在播放应用程序捆绑包中的视频。
他们正在正确播放。
但是,当我调用关闭AVPlayerViewController时,它显然已从视图层次结构中删除,但是,如果我关闭iOS设备并再次将其重新打开,则在锁定屏幕上会显示一个媒体控件,以显示该视频和一个“播放”按钮。
如果您触摸“播放”,则只会获得音频而没有视频。
我的问题是我不明白为什么“解雇”在用完后并不能完全“杀死”玩家。
这是演示代码:
let path = Bundle.main.path(forResource: filename, ofType: type)
let url = NSURL(fileURLWithPath: path!)
let player = AVPlayer(url: url as URL)
NotificationCenter.default.addObserver(self,
selector: #selector(VideoLibraryViewController.didFinishPlaying(notification:)),
name: NSNotification.Name.AVPlayerItemDidPlayToEndTime,
object: player.currentItem)
self.playerController = AVPlayerViewController()
self.playerController?.player = player
self.playerController?.allowsPictureInPicturePlayback = true
self.playerController?.showsPlaybackControls = YES
self.playerController?.delegate = self
self.playerController?.player?.play()
self.present(self.playerController!, animated: true, completion : nil)
以下是解雇代码:
// Delegate can implement this method to be notified when Picture in Picture will start.
func playerViewController(_ playerViewController: AVPlayerViewController, willEndFullScreenPresentationWithAnimationCoordinator coordinator: UIViewControllerTransitionCoordinator)
{
self.playerController?.dismiss(animated: NO, completion: nil )
}
这是锁屏/控制中心上显示的系统范围媒体播放器中剩余的内容:
答案 0 :(得分:1)
仅适用于iOS 13 SDK:这是解决方案,但答案是,尽管关闭了AVPlayerViewController,但它知道的AVPlayer对象是持久的,需要将其设置为nil。
private func killVideoPlayer()
{
self.playerController?.player?.pause()
self.playerController?.player = nil
self.playerController?.dismiss(animated: YES, completion: { self.playerController = nil })
}
以前的SDK,仍然无法正常工作。
都没有将AVAudioSession.active设置为false ...?!?!仍然需要iOS 13之前的SDK解决方案。
