08-MPMoviePlayerController/MPMoviePlayerViewController

        ios播放视频文件一般使用 MPMoviePlayerViewController 和 MPMoviePlayerController。前者是一个view，后者是个Controller。区别就是MPMoviePlayerViewController里面包含了一个MPMoviePlayerController
         这两个都继承于NSObject,都能播放本地视频、流媒体、网络视频

        首先要包含   #import  <MediaPlayer/MediaPlayer.h>头文件
@"http://bcs.duapp.com/chenwei520/media/mobile_vedio.mp4"

一、MPMoviePlayerController 自定义播放视频方法

MPMoviePlayerController *movie; - (void)viewDidLoad {     [super viewDidLoad]; if(movie == nil)          NSURL *url = [NSURL                     URLWithString:@"http://bcs.duapp.com/chenwei520/media/mobile_vedio.mp4"];      movie = [[MPMoviePlayerController alloc] initWithContentURL:url];     movie.view.frame = CGRectMake(20, 20, 200, 200);     movie.controlStyle = MPMovieControlStyleFullscreen;    [self.view addSubview:movie.view];  }       // 注册一个播放结束的通知     [[NSNotificationCenter defaultCenter] addObserver:self                                              selector:@selector(myMovieFinishedCallback:)                                                  name:MPMoviePlayerPlaybackDidFinishNotification                                                object:movie];     [movie play]; } #pragma mark -------------------视频播放结束委托-------------------- /*  @method 当视频播放完毕释放对象  */ -(void)myMovieFinishedCallback:(NSNotification*)notify {     //视频播放对象     MPMoviePlayerController* theMovie = [notify object];     //销毁播放通知     [[NSNotificationCenter defaultCenter] removeObserver:self                                                     name:MPMoviePlayerPlaybackDidFinishNotification                                                   object:theMovie];     [theMovie.view removeFromSuperview]; }

二、MPMoviePlayerViewController 自定义播放视频方法

注意：MPMoviePlayerViewController 必须  presentMoviePlayerViewControllerAnimated方式添加，否则Done按钮是不会响应通知MPMoviePlayerPlaybackDidFinishNotification事件的； --------------------------------------------------------代码-------------------------------------------------- MPMoviePlayerViewController *moviePlayer; - (IBAction)play:(UIButton *)sender {     MPMoviePlayerViewController *moviePlay = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:@"http://bcs.duapp.com/chenwei520/media/mobile_vedio.mp4"]];     moviePlay.moviePlayer.view.backgroundColor = [UIColor clearColor];    //    moviePlay.moviePlayer.controlStyle = MPMovieControlStyleFullscreen;         /**缓存*/     [moviePlay.moviePlayer prepareToPlay];         /**播放*/     [moviePlay.moviePlayer play];         [self presentMoviePlayerViewControllerAnimated:moviePlay];         /**注册通知事件*/     [[NSNotificationCenter defaultCenter] addObserver:self                                              selector:@selector(myMovieFinishedCallback:)                                                 name:MPMoviePlayerPlaybackDidFinishNotification                                               object:nil]; } //通知触发事件方法 - (void)myMovieFinishedCallback:(NSNotification *)notif {     //拿到播放器     MPMoviePlayerController *player = notif.object;         if (player.playbackState == MPMoviePlaybackStateStopped) {         NSLog(@"停止播放");     }     //销毁通知     [[NSNotificationCenter defaultCenter] removeObserver:self                                                     name:MPMoviePlayerPlaybackDidFinishNotification                                                   object:player];         //移除视图     [player.view removeFromSuperview]; } --------------------------------------------------------代码-------------------------------------------------- 以下是资料 moviePlayer.moviewControlMode = MPMovieControlModeDefault; MPMovieControlModeDefault             显示播放 / 暂停、音量和时间控制 MPMovieControlModeVolumeOnly          只显示音量控制 MPMovieControlModeHidden              没有控制器 moviePlayer.scallingMode = MPMovieScallingModeAspectFit; 你可以使用下列宽高比值： MPMovieScallingModeNone             不做任何缩放 MPMovieScallingModeAspectFit        适应屏幕大小，保持宽高比 MPMovieScallingModeAspectFill       适应屏幕大小，保持宽高比，可裁剪 MPMovieScallingModeFill             充满屏幕，不保持宽高比 MPMoviePlayerContentPreloadDidFinishNotification 当电影播放器结束对内容的预加载后发出。因为内容可以在仅加载了一部分的情况下播放，所以这个通知可能在已经播放后才发出。 MPMoviePlayerScallingModeDidChangedNotification 当用户改变了电影的缩放模式后发出。用户可以点触缩放图标，在全屏播放和窗口播放之间切换。 MPMoviePlayerPlaybackDidFinishNotification 当电影播放完毕或者用户按下了 Done 按钮后发出
