How to detect when an AVPlayerItem is finished playing?

Question

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?

It uses NSNotification to alert when playback is finished.

Register for the notification:

[[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
}

you can use `[avPlayer currentItem]` if you use AVPlayerViewController – abhimuralidharan Jan 27 '16 at 12:00

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)
    }

}

Good answer but be sure to invoke removeObserver(_:name:object:) before observer or any object specified in addObserver:selector:name:object: is deallocated. — pierre23, Oct 12 '16 at 23:58

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];
}
