First, grap all your paths:

NSString *firstVideoPath = [[NSBundle mainBundle] pathForResource:@"sample" ofType:@"m4v"];
NSString *secondVideoPath = [[NSBundle mainBundle] pathForResource:@"demo" ofType:@"mp4"];
NSString *thirdVideoPath = [[NSBundle mainBundle] pathForResource:@"3" ofType:@"m4v"];

AVPlayerItem *firstVideoItem = [AVPlayerItem playerItemWithURL:[NSURL fileURLWithPath:firstVideoPath]];
AVPlayerItem *secondVideoItem = [AVPlayerItem playerItemWithURL:[NSURL fileURLWithPath:secondVideoPath]];
AVPlayerItem *thirdVideoItem = [AVPlayerItem playerItemWithURL:[NSURL fileURLWithPath:thirdVideoPath]];

Init AVQueuePlayer:

AVQueuePlayer *queuePlayer = [AVQueuePlayer queuePlayerWithItems:@[firstVideoItem, secondVideoItem,thirdVideoItem]];

And finally use layer to display all movies as playlist.

AVPlayerLayer *layer = [AVPlayerLayer layer];

[layer setPlayer:queuePlayer];
[layer setFrame:CGRectMake(10, 10, 300, 200)];
[layer setBackgroundColor:[UIColor redColor].CGColor];
[layer setVideoGravity:AVLayerVideoGravityResizeAspectFill];

[self.view.layer addSublayer:layer];

[queuePlayer play];

Don't forget to add frameworks:

#import <QuartzCore/QuartzCore.h>
#import "AVFoundation/AVFoundation.h"
