iPhone：MPMoviePlayerController 在 iOS 5.0 上不旋转

Question

在我将 iPhone 升级到 iOS 5.0 之前，我的代码运行良好。 MPMoviePlayerViewController 过去可以正常工作，但在 iOS 5.0 上不起作用，因此我必须将 MPMoviePlayerController 用于 iOs 5.0 及更高版本。它工作正常，但 MPMoviePlayerController 不会像以前使用 MPMoviePlayerViewController 那样自动旋转。

以下是我的代码。谁能建议我如何让 MPMoviePlayerController 代码自动旋转？

 -(void)playVideo {
NSString *filePath = [appDelegate filePath:@"startup.mp4"]; 

if(!appDelegate.iOS5) {
    // This works perfectly till iOS 4 versions. Rotates automatically
    MPMoviePlayerViewController *videoController = [[[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:filePath]] autorelease];
    [self presentMoviePlayerViewControllerAnimated:videoController];
} else {
    // This doesn't rotate automatically
    NSURL *url = [NSURL fileURLWithPath:filePath];
    MPMoviePlayerController* moviePlayer =  [[[MPMoviePlayerController alloc] initWithContentURL:url] autorelease];

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

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
    return YES;
}

Answer 1

尝试继承 MPMoviePlayerController 并将方向强制为仅纵向。

- (BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {

      return (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft || toInterfaceOrientation == UIInterfaceOrientationLandscapeRight);
}

不是最好的解决方案，但我想它应该可以工作。
