本文介绍如何在iOS应用中使用AVKit和AVFoundation框架实现MP4视频的循环播放。通过设置视频路径，创建AVPlayerItem，并利用AVPlayer和AVPlayerLayer进行视频播放，同时添加播放完成通知确保视频循环播放。

app名.app→ShowInFinder→app名→显示包内容→拖入需要播放的Mp4

#import <AVKit/AVKit.h>
#import <AVFoundation/AVFoundation.h>

    NSString *videoPath = [[NSBundle mainBundle] pathForResource:@"LoginBackground.mp4" ofType:nil];
    NSURL *url = [NSURL fileURLWithPath:videoPath];
    AVPlayerItem *playerItem = [[AVPlayerItem alloc] initWithURL:url];
    _player = [AVPlayer playerWithPlayerItem:playerItem];
    AVPlayerLayer *playerLayer = [AVPlayerLayer playerLayerWithPlayer:_player];
    playerLayer.frame = CGRectMake(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT);
    playerLayer.videoGravity = AVLayerVideoGravityResizeAspect;
    [v.layer addSublayer:playerLayer];
    [_player play];
    //添加播放完成通知
    [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(runLoopTheMovie:) name:AVPlayerItemDidPlayToEndTimeNotification object:_player.currentItem];

#pragma mark - 接收播放完成的通知
- (void)runLoopTheMovie:(NSNotification *)notification {
    AVPlayerItem *playerItem = notification.object;
    [playerItem seekToTime:kCMTimeZero];
    [_player play];
}
