从webView（仅限肖像应用程序）执行UIMoviePlayer中的强制格局

Question

我在播放youtube视频时试用力量景观，从UIWebView中加载的移动版youtube执行，我有这个代码，它改变了方向，但是尽管改变了景观，UIMoviePlayer看起来仍然像它一样。 s处于纵向模式。

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(youTubeStarted:) name:@"UIMoviePlayerControllerDidEnterFullscreenNotification" object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(youTubeFinished:) name:@"UIMoviePlayerControllerDidExitFullscreenNotification" object:nil];



-(void)youTubeStarted:(NSNotification *)notification{
    NSLog(@"start");
    allowrotation = YES;
    [[UIDevice currentDevice] setValue:
     [NSNumber numberWithInteger: UIInterfaceOrientationLandscapeLeft]
                                forKey:@"orientation"];
}

-(void)youTubeFinished:(NSNotification *)notification{
    NSLog(@"done");
    allowrotation = NO;
    [[UIDevice currentDevice] setValue:
     [NSNumber numberWithInteger: UIInterfaceOrientationPortrait]
                                forKey:@"orientation"];
}
