废话不多说，直接上代码。

• 添加头文件

#import <MediaPlayer/MediaPlayer.h>

#import "YLPeerConnectionViewController.h"
#import <AVFoundation/AVFoundation.h>
@interface YLPeerConnectionViewController ()
//@property(nonatomic,strong)AVPlayer *player;

@property (nonatomic,strong) MPMoviePlayerController *moviePlayer;//视频播放控制器

@end

• 实现方法

@implementation YLPeerConnectionViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    self.view.backgroundColor=[UIColor whiteColor];
    //播放
    [self.moviePlayer play];
    
    //添加通知
    [self addNotification];
}

• 移除所有通知监控

-(void)dealloc{
    //移除所有通知监控
    [[NSNotificationCenter defaultCenter] removeObserver:self];
}

• 文件路径

#pragma mark - 私有方法
-(NSURL *)getFileUrl{
//    NSString *urlStr=[[NSBundle mainBundle] pathForResource:@"The New Look of OS X Yosemite.mp4" ofType:nil];
   
    NSBundle *bundle = [NSBundle mainBundle];
    NSString *filePath = [bundle pathForResource:@"视频" ofType:@"mov"];
//    filePath = self.videoPath;
    NSURL *url=[NSURL fileURLWithPath:filePath];
    return url;
}

• 创建媒体播放控制器

-(MPMoviePlayerController *)moviePlayer{
    if (!_moviePlayer) {
        NSURL *url=[self getFileUrl];
        _moviePlayer=[[MPMoviePlayerController alloc]initWithContentURL:url];
        _moviePlayer.view.frame=self.view.bounds;
        _moviePlayer.view.autoresizingMask=UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight;
        [self.view addSubview:_moviePlayer.view];
    }
    return _moviePlayer;
}

• 添加通知监控媒体播放控制器状态

-(void)addNotification{
    NSNotificationCenter *notificationCenter=[NSNotificationCenter defaultCenter];
    [notificationCenter addObserver:self selector:@selector(mediaPlayerPlaybackStateChange:) name:MPMoviePlayerPlaybackStateDidChangeNotification object:self.moviePlayer];
    [notificationCenter addObserver:self selector:@selector(mediaPlayerPlaybackFinished:) name:MPMoviePlayerPlaybackDidFinishNotification object:self.moviePlayer];
    
}

• 播放状态改变，注意播放完成时的状态是暂停

/**
 *
 *  @param notification 通知对象
 */
-(void)mediaPlayerPlaybackStateChange:(NSNotification *)notification{
    switch (self.moviePlayer.playbackState) {
        case MPMoviePlaybackStatePlaying:
            NSLog(@"正在播放...");
            break;
        case MPMoviePlaybackStatePaused:
            NSLog(@"暂停播放.");
            break;
        case MPMoviePlaybackStateStopped:
            NSLog(@"停止播放.");
            break;
        default:
            NSLog(@"播放状态:%li",self.moviePlayer.playbackState);
            break;
    }
}

• 播放完成

/**
 *
 *  @param notification 通知对象
 */
-(void)mediaPlayerPlaybackFinished:(NSNotification *)notification{
    NSLog(@"播放完成.%li",self.moviePlayer.playbackState);
}
