方法一:

- (void)viewDidLoad

{

    [super viewDidLoad];

    // Do any additional setup after loading the view.

    //利用自带MPMoviePlayerController来实现视频播放,首先要在 项目中导入MediaPlayer.Framework框架包.

    //在试图控制器中导入#import "MediaPlayer/MPMoviePlayerController.h"

    UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 568)];

    imageView.image = [UIImage imageNamed:@"00013"];

    [self.view addSubview:imageView];

    [imageView release];

    // 播放视频按钮

    UIButton *playButton = [UIButton buttonWithType:UIButtonTypeSystem];

    playButton.frame = CGRectMake(200, 30, 100, 30);

    [playButton addTarget:self action:@selector(playClick:) forControlEvents:UIControlEventTouchUpInside];

    playButton.backgroundColor = [UIColor greenColor];

    playButton.layer.cornerRadius = 5;

    playButton.layer.masksToBounds = YES;

    [self.view addSubview:playButton];

}

- (void)playClick:(UIButton *)btn

{

    NSString *path = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"mp4"];

    //视频URL

    movie.controlStyle = MPMovieControlStyleFullscreen;

    [movie.view setFrame:self.view.bounds];

    movie.initialPlaybackTime = -1;

    [self.view addSubview:movie.view];

    //注冊一个播放结束的通知, 当播放结束时, 监听到而且做一些处理

    //播放器自带有播放通知的功能, 在此只只须要注冊观察者监听通知的就可以

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(myMovieFinishedCallback:) name:MPMoviePlayerPlaybackDidFinishNotification

      object:movie];

    [movie play];

}

- (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)];

    //释放视频对象

    [theMovie.view release];

}

方法二:

- (void)viewDidLoad

    [_moviePlayerController.moviePlayer setFullscreen:NO animated:YES];

    [_moviePlayerController.moviePlayer play];

    //视频播放组件的容器,加这个容器是为了兼容iOS6,假设不加容器在iOS7以下没有不论什么问题,假设在iOS6以下视频的播放画面会自己主动铺满self.view;

    UIView *moviePlayView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 320, 568)];

    [self.view addSubview:moviePlayView];
