利用MPMoviePlayerViewController实现简单的mp4播放

// 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];
