IOS系统的四层结构：核心操作系统层：Core OS,核心服务层：Core Services，媒体层：Media，Cocoa Touch层。

使用MediaPlayer：

1.引入MediaPlayer.frame框架，引入头文件#import <MediaPlayer/MediaPlayer.h>

2.通过设置MPMoviePlayerViewController来设置全屏的播放：

MPMoviePlayerController *_moviePlayer;

MPMoviePlayerViewController *_mpMovieViewController;

NSString *filePath = [[NSBundle mainBundle]pathForResource:@"moxue" ofType:@"mp4"];//视频文件路径
    _mpMovieViewController = [[MPMoviePlayerViewController alloc]initWithContentURL:[NSURL fileURLWithPath:filePath]];//将路径添加到MPMoviePlayerViewController
    [_mpMovieViewController.moviePlayer play];//设置moviePlayer播放
    [self.view addSubview:_mpMovieViewController.view];//将MPMoviePlayerViewController添加到view上。

3.通过设置MPMoviePlayerController在view上设置播放屏幕的大小：

NSString *filePath = [[NSBundle mainBundle]pathForResource:@"moxue" ofType:@"mp4"];//视频文件路径
    _mpMovieViewController = [[MPMoviePlayerViewController alloc]initWithContentURL:[NSURL fileURLWithPath:filePath]];//将路径添加到MPMoviePlayerViewController
 _moviePlayer = [_mpMovieViewController moviePlayer];//设置播放器
    _moviePlayer.view.frame = CGRectMake(50, 100, 300, 200);//设置播放器大小
   _moviePlayer.view.backgroundColor = [UIColor redColor];//设置背景颜色
    [_moviePlayer play];//播放
    [self.view addSubview:_moviePlayer.view];//添加到视图
    
    _moviePlayer.controlStyle = MPMovieControlStyleEmbedded;//控件选择
    _moviePlayer.scalingMode = MPMovieScalingModeAspectFit;//屏幕缩放

4.设置播放器的一些监听方法：

 [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(notificationObserver:) name:MPMoviePlayerDidEnterFullscreenNotification object:nil];//添加进入全屏的监听
}
-(void)notificationObserver:(NSNotification *)info
{
    NSLog(@"%@",info);
}
