ios 视频播放／直播demo

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 setTitle:@"播放视频" forState:UIControlStateNormal]; 

       

    playButton.backgroundColor = [UIColor greenColor]; 

    playButton.layer.cornerRadius = 5; 

    playButton.layer.masksToBounds = YES; 

    [self.view addSubview:playButton]; 

} 

   

- (void)playClick:(UIButton *)btn 

{ 

    //视频文件路径,此视频已经存入项目包中.属于本地播放 

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

    //视频URL 

    NSURL *url = [NSURL fileURLWithPath:path]; 

    //视频播放对象 

    MPMoviePlayerController *movie = [[MPMoviePlayerController alloc] initWithContentURL:url]; 

    movie.controlStyle = MPMovieControlStyleFullscreen; 

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

    movie.initialPlaybackTime = -1; 

    [self.view addSubview:movie.view]; 

    //注册一个播放结束的通知, 当播放结束时, 监听到并且做一些处理 

    //播放器自带有播放通知的功能, 在此仅仅只需要注册观察者监听通知的即可 

    [[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 

{ 

    //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/MediaPlayer.h> 

    [super viewDidLoad]; 

    // Do any additional setup after loading the view. 

    NSURL *videoURL; 

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

    //判断是网络地址还是本地播放地址 

    if ([path hasPrefix:@"http://"]) { 

        videoURL = [NSURL URLWithString:path];  

    }else{ 

        videoURL = [NSURL fileURLWithPath:path]; 

    } 

    MPMoviePlayerViewController *_moviePlayerController= [[MPMoviePlayerViewController alloc] initWithContentURL:videoURL]; 

    [_moviePlayerController.view setFrame:CGRectMake(0,100,320,200)]; 

    _moviePlayerController.moviePlayer.movieSourceType=MPMovieSourceTypeFile; 

    [_moviePlayerController.moviePlayer setScalingMode:MPMovieScalingModeNone]; 

    [_moviePlayerController.moviePlayer setRepeatMode:MPMovieRepeatModeNone]; 

    [_moviePlayerController.moviePlayer setControlStyle:MPMovieControlModeVolumeOnly]; 

    [_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,如果不加容器在iOS7下面没有任何问题,如果在iOS6下面视频的播放画面会自动铺满self.view; 

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

    [self.view addSubview:moviePlayView]; 

    [moviePlayView addSubview:[_moviePlayerController.moviePlayer view]];
