MPMoviePlayerViewController没有出现

Question

我正在尝试为“标题/启动画面”加载小电影。 但是，当我调用presentMoviePlayerViewControllerAnimated没有任何反应。 我已经确认正在执行该代码块，但是用户看不到任何东西。

我的目标是iPad，因此假定为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];
}

Answer 1

您应该放置一行[playerView版本]； 在此行之后[self dismissMoviePlayerViewControllerAnimated];
