MPMoviePlayerViewController 未出现
我正在尝试为标题/启动屏幕加载一部小电影。但是，当我调用 presentMoviePlayerViewControllerAnimated 时，什么也没有发生。我已经确认该代码块正在执行，但用户无法感知到任何内容。
我的目标是 iPad，因此假设为 3.2。
任何帮助将不胜感激。
- (void)viewDidLoad {
[super viewDidLoad];
NSString *path = [[NSBundle mainBundle] pathForResource:@"Intro" ofType:@"m4v" inDirectory:nil];
NSURL *fileURL = [NSURL fileURLWithPath:path];
MPMoviePlayerViewController *playerView = [[MPMoviePlayerViewController alloc] initWithContentURL:fileURL];
[[NSNotificationCenter defaultCenter] addObserver:self selector: @selector(playbackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:playerView.moviePlayer];
[self presentMoviePlayerViewControllerAnimated:playerView];
[playerView release];
}
- (void)playbackDidFinish:(NSNotification*)aNotification {
MPMoviePlayerController *player = [aNotification object];
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:player];
[player stop];
[self dismissMoviePlayerViewControllerAnimated];
}
I'm attempting to load a small movie for a Title/Splash screen. However, when I call presentMoviePlayerViewControllerAnimated nothing happens. I have confirmed that the block of code is being executed, but there is nothing perceptible to the user.
I am targeting the iPad, so 3.2 is assumed.
Any help would be appreciated.

你应该放置这条线

后
这条线
[自我解雇MoviePlayerViewControllerAnimated]；
you should place the line
[playerView release];
after
this line
[self dismissMoviePlayerViewControllerAnimated];
