Skip to Previous AVPlayerItem on AVQueuePlayer / Play selected Item from queue

The following code allows you to jump to any item in your. No playerhead advancing. Plain and simple. playerItemList is your NSArray with AVPlayerItem objects.

- (void)playAtIndex:(NSInteger)index
{
    [audioPlayer removeAllItems];
    AVPlayerItem* obj = [playerItemList objectAtIndex:index];
    [obj seekToTime:kCMTimeZero];
    [audioPlayer insertItem:obj afterItem:nil];
    [audioPlayer play];
}

If you want your program can play previous item and play the selected item from your playeritems(NSArray),you can do this.

- (void)playAtIndex:(NSInteger)index
{
    [player removeAllItems];
    for (int i = index; i <playerItems.count; i ++) {
        AVPlayerItem* obj = [playerItems objectAtIndex:i];
        if ([player canInsertItem:obj afterItem:nil]) {
        [obj seekToTime:kCMTimeZero];
        [player insertItem:obj afterItem:nil];
        }
    }
}

edit: playerItems is the NSMutableArray(NSArray) where you store your AVPlayerItems.

The first answer removes all items from AVQueuePlayer, and repopulates queue starting with iteration passed as index arg. This would start the newly populated queue with previous item(assuming you passed correct index) as well the rest of the items in existing playerItems array from that point forward, BUT it does not allow for multiple reverses, e.g. you are on track 10 and want to go back and replay track 9, then replay track 5, with above you cannot accomplish. But here you can...

-(IBAction) prevSongTapped: (id) sender
{
    if (globalSongCount>1){ //keep running tally of items already played
    [self resetAVQueue]; //removes all items from AVQueuePlayer

        for (int i = 1; i < globalSongCount-1; i++){
            [audioQueuePlayer advanceToNextItem];
        }
   globalSongCount--;
   [audioQueuePlayer play];


    }
}
