MPMoviePlayerController 在点击“完成”时提供无限循环

Question

我尝试让 MPMoviePlayerController 工作，但遇到了一个奇怪的问题。播放时，我单击“完成”按钮，似乎触发了无限的外观：

2012-02-13 15:18:04.395 iDomsPortalDev[7376:12203] 播放完毕。 原因：用户退出 2012-02-13 15:18:04.395 iDomsPortalDev[7376:12203] 播放完毕。原因：用户退出 2012-02-13 15:18:04.395 iDomsPortalDev[7376:12203]播放完成。原因：用户退出

我在启动时使用以下通知：

- (void) showMoviePlayer {
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(willEnterFullscreen:) name:MPMoviePlayerWillEnterFullscreenNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(willExitFullscreen:) name:MPMoviePlayerWillExitFullscreenNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(enteredFullscreen:) name:MPMoviePlayerDidEnterFullscreenNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(exitedFullscreen:) name:MPMoviePlayerDidExitFullscreenNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playbackFinished:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil];      

    id appDelegate = (iDomsAppDelegate *)[[UIApplication sharedApplication] delegate];
    //[[self navigationController] presentMoviePlayerViewControllerAnimated:[appDelegate movieController]];    
    [[appDelegate moviePlayer].view setFrame: self.view.bounds];
    [self.view addSubview:[appDelegate moviePlayer].view];
    [[appDelegate moviePlayer] setFullscreen:YES animated:YES];    
}

以及以下侦听器：

#pragma mark - Movieplayer feedback
- (void)willEnterFullscreen:(NSNotification*)notification {
    NSLog(@"willEnterFullscreen");
}

- (void)enteredFullscreen:(NSNotification*)notification {
    NSLog(@"enteredFullscreen");
}

- (void)willExitFullscreen:(NSNotification*)notification {
    NSLog(@"willExitFullscreen");
}

- (void)exitedFullscreen:(NSNotification*)notification {
    NSLog(@"exitedFullscreen");
    iDomsAppDelegate *appDelegate = (iDomsAppDelegate *)[[UIApplication sharedApplication] delegate];    
    [[appDelegate moviePlayer].view removeFromSuperview];
    [[appDelegate moviePlayer] release];
    [appDelegate setMovieController:nil];
    [[NSNotificationCenter defaultCenter] removeObserver:self];
}

- (void)playbackFinished:(NSNotification*)notification {
    iDomsAppDelegate *appDelegate = (iDomsAppDelegate *)[[UIApplication sharedApplication] delegate];    
    NSNumber* reason = [[notification userInfo] objectForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey];
    switch ([reason intValue]) {
        case MPMovieFinishReasonPlaybackEnded:
            NSLog(@"playbackFinished. Reason: Playback Ended");         
            break;
        case MPMovieFinishReasonPlaybackError:
            NSLog(@"playbackFinished. Reason: Playback Error");
            break;
        case MPMovieFinishReasonUserExited:
            NSLog(@"playbackFinished. Reason: User Exited");
            break;
        default:
            break;
    }
    [[appDelegate moviePlayer] setFullscreen:NO animated:YES];
}

仅调用 PlayBackFinished 选择器（无限次），因此我一定做了一些愚蠢的事情（在 iOS5 的模拟器中运行）

Answer 1

我发现了问题，似乎是设置了全屏选项导致的：

[[appDelegate moviePlayer] setFullscreen:YES animated:YES];
