No AVPlayer Delegate? How to track when song finished playing? Objective C iPhone development

Yes, the AVPlayer class does not have a delegate protocol like the AVAudioPlayer. You need to subscribe to notifications on an AVPlayerItem. You can create an AVPlayerItem using the same URL that you would otherwise pass to -initWithURL: on AVPlayer.

-(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];    // Pass the AVPlayerItem to a new player    AVPlayer* player = [[[AVPlayer alloc] initWithPlayerItem:playerItem] autorelease];    // Begin playback    [player play]} -(void)itemDidFinishPlaying:(NSNotification *) notification {    // Will be called when AVPlayer finishes playing playerItem}

Yes. Add a KVO observer to the player's status or rate:

- (IBAction)go {   self.player = .....   self.player.actionAtItemEnd = AVPlayerActionStop;   [self.player addObserver:self forKeyPath:@"rate" options:0 context:0]; }- (void)stopped {    ...    [self.player removeObserver:self]; //assumes we are the only observer}- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context {    if (context == 0) {        if(player.rate==0.0) //stopped            [self stopped];    }    else        [super observeVal...];}

So basically, that's it.

Disclaimer: I wrote that in here so I didn't check if the code was good. ALSO I never used AVPlayer before but it should be about right.

Swift 3 - I add an observer to AVPlayerItem every time I add a video to the player:

func playVideo(url: URL) {  let playerItem = AVPlayerItem(asset: AVURLAsset(url: someVideoUrl))  NotificationCenter.default.addObserver(self, selector: #selector(playerItemDidPlayToEndTime), name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: playerItem)  self.player.replaceCurrentItem(with: playerItem)  self.player.play()}func playerItemDidPlayToEndTime() {  // load next video or something}
