我尝试了这个但不起作用我可以听到声音但我看不到图像..我该如何解决这个问题？
in app delegate class:
在应用程序委托类中：
- (IBAction)tanitimVideo:(id)sender {
// create our UnifeyeMobileViewController and present it
video* unifeyeMobileViewController = [[video alloc] initWithNibName:@"video" bundle:nil];
unifeyeMobileViewController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[viewController presentModalViewController:unifeyeMobileViewController animated:YES];
[unifeyeMobileViewController release];
}
in video.m class:
在 video.m 类中：
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
NSBundle *bundle = [NSBundle mainBundle];
NSString *moviePath = [bundle pathForResource:@"debutteaser" ofType:@"mp4"];
NSURL *movieURL = [[NSURL fileURLWithPath:moviePath] retain];
MPMoviePlayerController *theMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
theMovie.scalingMode = MPMovieScalingModeAspectFill;
[theMovie play];
MPMoviePlayerViewController *moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:movieURL];
[self presentMoviePlayerViewControllerAnimated:moviePlayer];
}

Try using MPMoviePlayerViewControllerinstead, very little code to get it working and you can do it all from your app delegate ;)
尝试使用MPMoviePlayerViewController代替，只需很少的代码即可使其工作，您可以从应用程序委托中完成所有操作；)
- (IBAction)tanitimVideo:(id)sender {
NSBundle *bundle = [NSBundle mainBundle];
NSString *moviePath = [bundle pathForResource:@"debutteaser" ofType:@"mp4"];
MPMoviePlayerViewController *mp = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:moviePath]];
mp.moviePlayer.scalingMode = MPMovieScalingModeAspectFill;
[self presentMoviePlayerViewControllerAnimated:mp];
[mp release];
}

Look at your .m file-
看看你的 .m 文件-
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
NSBundle *bundle = [NSBundle mainBundle];
NSString *moviePath = [bundle pathForResource:@"debutteaser" ofType:@"mp4"];
NSURL *movieURL = [[NSURL fileURLWithPath:moviePath] retain];
MPMoviePlayerController *theMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
theMovie.scalingMode = MPMovieScalingModeAspectFill;
[theMovie play];
////////// <<<<<>>>>>>>>>> //////////
MPMoviePlayerViewController *moviePlayer = [[MPMoviePlayerViewController alloc]
initWithContentURL:movieURL];
[self presentMoviePlayerViewControllerAnimated:moviePlayer];
}
why do you make 2 controllers (theMovie , moviePlayer) and you setting all in theMovie but running the moviePlayer.
为什么要制作 2 个控制器（theMovie、moviePlayer）并在 theMovie 中设置所有内容但运行 moviePlayer。
it's should be like this: - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view from its nib.
它应该是这样的： - (void)viewDidLoad { [super viewDidLoad]; // 从其笔尖加载视图后进行任何其他设置。
NSBundle *bundle = [NSBundle mainBundle];
NSString *moviePath = [bundle pathForResource:@"debutteaser" ofType:@"mp4"];
NSURL *movieURL = [[NSURL fileURLWithPath:moviePath] retain];
MPMoviePlayerController *theMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL];
theMovie.scalingMode = MPMovieScalingModeAspectFill;
[theMovie setShouldAutoplay:YES];
[self presentMoviePlayerViewControllerAnimated:theMovie];
}
hope it's help.
希望有帮助。
