播放视频：

需要添加MediaPlayer.framework框架：

需要：#import <MediaPlayer/MediaPlayer.h>

.h文件里面首先声明全局变量：

            @property (retain, nonatomic) MPMoviePlayerViewController *movie;
            @property (retain, nonatomic) UIView *aview;
      .m文件代码如下：

//viewDidLoad里添加如下代码：

    //加载视频
    UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    button.frame = CGRectMake(100, 400, 50, 44);
    [button setTitle:@"ok" forState:UIControlStateNormal];
    [button addTarget:self action:@selector(playMovie) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:button];

//播放视频

- (void)playMovie

{

NSString *path = [[NSBundle mainBundle] pathForResource:@"cyborg" ofType:@"m4v"];

NSURL *url = [NSURL fileURLWithPath:path];

self.movie = [[MPMoviePlayerViewController alloc] initWithContentURL:url];

self.movie.view.frame = CGRectMake(60, 60, 200, 200);

//self.movie.moviePlayer.controlStyle = MPMovieControlStyleEmbedded;//嵌入式

self.movie.moviePlayer.controlStyle = MPMovieControlStyleFullscreen;

[self presentMoviePlayerViewControllerAnimated:self.movie];

self.aview = [[UIView alloc] initWithFrame:CGRectMake(60, 120, 200, 200)];

[self.aview addSubview:self.movie.view];

[self.view addSubview:self.aview];

//添加播放结束时的通知

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(videoDidFinished:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];

}

- (void)videoDidFinished:(NSNotification *)notice

{

[self.movie.view removeFromSuperview];

[self.aview removeFromSuperview];

self.movie = nil;

//移除通知

[[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:nil];

}
