利用MPMoviePlayerViewController实现简单的mp4播放

1、要使用MPMoviePlayerViewController首先要加入MediaPlayer.framework. 
2、加入如下代码：

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.

- (void)viewDidLoad {

    [super viewDidLoad];

    NSString *url = [[NSBundle mainBundle] pathForResource:@"TaylorSwift-LoveStory" ofType:@"mp4"];

    

    MPMoviePlayerViewController *playerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL fileURLWithPath:url]];

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(movieFinishedCallback:)

                                                 name:MPMoviePlayerPlaybackDidFinishNotification

                                               object:[playerViewController moviePlayer]];

    //-- add to view---

    [self.view addSubview:playerViewController.view];

    

    //---play movie---

    MPMoviePlayerController *player = [playerViewController moviePlayer];

    [player play];

    

}



- (void) movieFinishedCallback:(NSNotification*) aNotification {

    MPMoviePlayerController *player = [aNotification object];

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

    [player stop];

    [self.view removeFromSuperView];

    [player autorelease];

}

3、支持横屏修改shouldAutorotateToInterfaceOrientation:interfaceOrientation方法使其返回YES。

备注：实测 用上面的方法直接播放本地m3u8格式或者线上的视频也是可以的。

 

NSURL可直接初始化：

NSURL*videoPathURL=[NSURL URLWithString:urlStr];//urlStr是视频播放地址

如果是播放本地视频的话。这样初始化：

NSURL*videoPathURL=[[NSURL alloc] initFileURLWithPath:urlStr];
