iPhone SDK 4：來自MPMoviePlayerViewController的視頻自動旋轉

Question

拜托你給的例子shouldAutorotateToInterfaceOrientation方法用法MPMoviePlayerViewController的一部分嗎？ 據我所知，使用shouldAutorotateToInterfaceOrientation方法不僅可用於UIView的同時也為MPMoviePlayerViewController SDK 3.2以來。 我一直在3.1的UIView中使用它，但是我不明白如何在MPMoviePlayerViewController類中使用它。

這是我現在擁有的：

-(IBAction) playMovie {

//declaring path to file and stuff...

    MPMoviePlayerViewController *playerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:url];

        [[NSNotificationCenter defaultCenter] addObserver:self
                                                 selector:@selector(moviePlayBackDidFinish:)
                                                     name:MPMoviePlayerPlaybackDidFinishNotification
                                                   object:[playerViewController moviePlayer]];

        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:[playerViewController moviePlayer]];      

        MPMoviePlayerController *player = [playerViewController moviePlayer];
        [self.view addSubview:playerViewController.view];
        player.controlStyle = MPMovieControlStyleDefault;
        player.shouldAutoplay = YES;
        [player setFullscreen:YES animated:YES];
    } 

    - (void)moviePlayBackDidFinish:(NSNotification*)notification {
        MPMoviePlayerViewController *moviePlayer = [notification object];
        [[NSNotificationCenter defaultCenter] removeObserver:self
                                                        name:MPMoviePlayerPlaybackDidFinishNotification
                                                      object:moviePlayer];

        [moviePlayer.view removeFromSuperview];

        [moviePlayer release];  
    }

它工作正常，但我需要知道如何實現視頻自動旋轉。 UIView中用於它的方法無濟於事。

謝謝。

嗯，聽起來很奇怪，但是我確定此方法一定不能聲明為ideide playMovie塊。 我錯了，下面的代碼像往常一樣粘貼，並且可以滿足我的需要。

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    // Return YES for supported orientations
    if (interfaceOrientation == UIInterfaceOrientationPortrait ||
        interfaceOrientation == UIInterfaceOrientationLandscapeLeft ||
        interfaceOrientation == UIInterfaceOrientationLandscapeRight)
        return YES;
    else {
        return NO;
    }

}
