Question

我使用AVPlayer来显示一些视频流（具有固定长度）。问题是当内容完成时，播放器（如果用户已将其设置为全屏）仍然保持全屏。

任何方法可以让玩家在内容播放结束后立即进入最小化状态？

再加上龙陇的回答，

您可以在itemDidFinishPlaying函数中使用dismissViewControllerAnimated关闭视频播放器。你还应该记得在完成后删除你创建的观察者。

Answer 2

适用于#iOS 10版及更高版本

    # declare your player and 
    var player = AVPlayer()
    var playerVC = AVPlayerViewController()


    let item = AVPlayerItem(url: module.fileURL!)
    DispatchQueue.main.async(execute: {
        self.playerVC.view.backgroundColor = UIColor.clear
        self.player.replaceCurrentItem(with: item)
        try? AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
        self.playerVC.player = self.player

        self.player.play()

        self.playerVC.showsPlaybackControls = true
        if #available(iOS 11.0, *) {
            self.playerVC.exitsFullScreenWhenPlaybackEnds = true
        }
        self.playerVC.view.frame = self.videoView.bounds
        NotificationCenter.default.addObserver(self, selector: #selector(self.playerItemDidReachEnd(notification:)), name: .AVPlayerItemDidPlayToEndTime, object:self.playerVC.player!.currentItem)
        self.videoView.addSubview((self.playerVC.view)!)

})

收听视频文件的结尾

  @objc func playerItemDidReachEnd(notification: Notification?) {
    print("Finishing")
    dismiss(animated: true, completion: nil)
}

Answer 3

收听视频文件的结尾并在结尾处关闭/调整大小/重新启动视图

-(void)startPlaybackForItemWithURL:(NSURL*)url {

 // First create an AVPlayerItem
 AVPlayerItem* playerItem = [AVPlayerItem playerItemWithURL:url];

 // Subscribe to the AVPlayerItem's DidPlayToEndTime notification.
 [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(itemDidFinishPlaying:) name:AVPlayerItemDidPlayToEndTimeNotification object:playerItem];

// Begin playback
[player play]

} 

-(void)itemDidFinishPlaying:(NSNotification *) notification {
 // Will be called when AVPlayer finishes playing playerItem

}

AVPlayer在完成播放时退出全屏
