    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.
