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。

 

 -(void)myMovieFinishedCallback:(NSNotification *)notification{

 

MPMoviePlayerController *player = [notification object];  

    [[NSNotificationCenter defaultCenter] removeObserver:self 

name:MPMoviePlayerPlaybackDidFinishNotification object:player];  

    [player stop];  

[playerView.view removeFromSuperview];

[self.view setNeedsLayout];

    [player autorelease];  

}

 

 

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

 

要用fileURLWithPath:  不然无法播放本地文件
