AVQueuePlayer AVPlayerItemDidPlayToEndTimeNotification fails to call - ios

Question

Im using AVQueuePlayer to loop through an array of AVPlayerItems.
The way I'm looping it, I listen to the AVPlayerItemDidPlayToEndTimeNotification and every time its called, I add the current object to the end of the queue.
heres the code:
viewWillAppear
{
...
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(playerItemDidReachEnd:)
name:AVPlayerItemDidPlayToEndTimeNotification
object:[_queuePlayer currentItem]];
[_queuePlayer play];
}
- (void)playerItemDidReachEnd:(NSNotification *)notification {
AVPlayerItem *p = [notification object];
AVPlayerItem *fakeNew = [[AVPlayerItem alloc] initWithAsset:p.asset];
if (_queuePlayer.items.count == 1)
{
[p seekToTime:kCMTimeZero];
[_queuePlayer play];
}
else
{
[_queuePlayer insertItem:fakeNew afterItem:[_queuePlayer.items lastObject]];
}
NSLog(#"array of items to play:%lu", (unsigned long)_queuePlayer.items.count);
}
The problem is, that the method is called only for the first video that plays, after that, the method stops getting called, so if for example i have 2 movies in the array, it would play them both+the first one again, any idea why is this happening?
More Info:
also tried to make a new player every time and set it to layer. failed to send the notification more than once just the same
- (void)playerItemDidReachEnd:(NSNotification *)notification {
AVPlayerItem *p = [notification object];
[self.playList removeObjectAtIndex:0];
[self.playList addObject:p];
AVPlayer *newPlayer = [[AVPlayer alloc] initWithPlayerItem:[self.playList objectAtIndex:0]];
_player = newPlayer;
self.AVPlayerLayerView.layer.player = self.player;
[_player play];
}

After a lot of messing around, apparently for whatever reason, the view unregistered as observer every time, I just removed and added observer after every notification:
- (void)playerItemDidReachEnd:(NSNotification *)notification {
AVPlayerItem *p = [notification object];
AVPlayerItem *fakeNewItem = [[AVPlayerItem alloc] initWithAsset:p.asset];
[self.playList removeObjectAtIndex:0];
[self.playList addObject:fakeNewItem];
AVPlayer *newPlayer = [[AVPlayer alloc] initWithPlayerItem:[self.playList objectAtIndex:0]];
_player = newPlayer;
self.AVPlayerLayerView.layer.player = self.player;
[[NSNotificationCenter defaultCenter] removeObserver:self];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(playerItemDidReachEnd:)
name:AVPlayerItemDidPlayToEndTimeNotification
object:[_player currentItem]];
[_player play];
}

For a clean approach to resolve this issue. I approached with the next piece of code instead
The first is you have to add the code necessary to receive a feedback from the AVPlayer when the reproduction time changes.
- (void)addPeriodicTimeObserverForReproductionChanges {
#weakify(self);
[self.player
addPeriodicTimeObserverForInterval:CMTimeMakeWithSeconds(kBQDefaultTimeIntervalReproductionChanges, NSEC_PER_SEC)
queue:self.eventsQueue
usingBlock:^(CMTime time) {
#strongify(self);
[self dispatchBlockOnMainQueue:^{
if ([self.delegate respondsToSelector:#selector(playerItemController:didChangeReproductionTime:)])
[self.delegate playerItemController:self
didChangeReproductionTime:time];
[self checkForItemPlayToEnd];
}];
}];
}
- (void)checkForItemPlayToEnd
{
CMTime durationScaled = CMTimeConvertScale(self.duration,self.player.currentTime.timescale, kCMTimeRoundingMethod_Default);
if (CMTIME_COMPARE_INLINE(durationScaled, ==, self.player.currentTime)) {
[self playerDidFinishReproducingItem];
}
}
