How to detect when an AVPlayerItem is finished playing? [duplicate]

问题

I've been looking through the AVPlayerItem and AVPlayer docs and there doesn't seem to be any callbacks for when the item is finished playing. I was hoping that there would be some sort of delegate callback that we can utilize or that AVPlayerActionAtItemEnd would provide a custom action for us to write.

How can i figure out a way to detect when AVPlayer has finished playing an item?

回答1:

It uses NSNotification to alert when playback is finished.

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(itemDidFinishPlaying:) name:AVPlayerItemDidPlayToEndTimeNotification object:playerItem];

Method to call when done:

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

Swift-i-fied (version 3)

class MyVideoPlayingViewController: AVPlayerViewController {

    override func viewDidLoad() {
        // Do any additional setup after loading the view.
        super.viewDidLoad()

        let videoURL = URL(fileURLWithPath: Bundle.main.path(forResource: "MyVideo", 
                                                                  ofType: "mp4")!)
        player = AVPlayer(url: videoURL)

        NotificationCenter.default.addObserver(self,
                                           selector: #selector(MyVideoPlayingViewController.animationDidFinish(_:)),
                                           name: .AVPlayerItemDidPlayToEndTime,
                                           object: player?.currentItem)
    }

    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        player?.play()
    }

    func animationDidFinish(_ notification: NSNotification) {
        print("Animation did finish")
    }

    deinit {
        NotificationCenter.default.removeObserver(self)
    }

}

This is how I did it.

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(movieFinishedCallback:) name:AVPlayerItemDidPlayToEndTimeNotification object:player.currentItem];


- (void)movieFinishedCallback:(NSNotification*)aNotification
{
   // [self dismissViewControllerAnimated:YES completion:Nil];
}
