方法一:- (void)viewDidLoad{    [super viewDidLoad];    // Do any additional setup after loading the view.      //利用內建MPMoviePlayerController來實現視頻播放,首先要在 項目中匯入MediaPlayer.Framework架構套件.    //在試圖控制器中匯入#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];        // 播放視頻按鈕    UIButton *playButton = [UIButton buttonWithType:UIButtonTypeSystem];    playButton.frame = CGRectMake(200, 30, 100, 30);    [playButton addTarget:self action:@selector(playClick:) forControlEvents:UIControlEventTouchUpInside];    [playButton setTitle:@"播放視頻" forState:UIControlStateNormal];        playButton.backgroundColor = [UIColor greenColor];    playButton.layer.cornerRadius = 5;    playButton.layer.masksToBounds = YES;    [self.view addSubview:playButton];}- (void)playClick:(UIButton *)btn{    //視頻檔案路徑,此視頻已經存入項目包中.屬於本地播放    NSString *path = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"mp4"];    //視頻URL    NSURL *url = [NSURL fileURLWithPath:path];    //視頻播放對象    MPMoviePlayerController *movie = [[MPMoviePlayerController alloc] initWithContentURL:url];    movie.controlStyle = MPMovieControlStyleFullscreen;    [movie.view setFrame:self.view.bounds];    movie.initialPlaybackTime = -1;    [self.view addSubview:movie.view];    //注冊一個播放結束的通知, 當播放結束時, 監聽到而且做一些處理    //播放器內建有播放通知的功能, 在此只只須要注冊觀察者監聽通知的就可以    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(myMovieFinishedCallback:) name:MPMoviePlayerPlaybackDidFinishNotification      object:movie];    [movie play];}- (void)myMovieFinishedCallback:(NSNotification *)notify{    //視頻播放對象    MPMoviePlayerController *theMovie = [notify object];    //銷毀播放通知    [[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:(theMovie)];    //釋放視頻對象    [theMovie.view release];}方法二:- (void)viewDidLoad{    //首先要在 項目中匯入MediaPlayer.Framework架構套件.    //在試圖控制器中匯入#import <MediaPlayer/MediaPlayer.h>    [super viewDidLoad];    // Do any additional setup after loading the view.
