iOS 6 MPMoviePlayerViewController和presentMoviePlayerViewControllerAnimated Rotation

Question

在之前的iOS版本中,我们的视频会自动旋转,但在iOS 6中则不再如此.我知道presentMoviePlayerViewControllerAnimated之前的设计是为了做到这一点,但我如何告诉MPMoviePlayerViewController自动旋转？

MPMoviePlayerViewController *moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:url];
[self presentMoviePlayerViewControllerAnimated:moviePlayer];

Answer 1

在appdelegate.m中:

- (NSUInteger) application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
    if ([[self.window.subviews.lastObject class].description isEqualToString:@"MPMovieView"]) {
        return UIInterfaceOrientationMaskAllButUpsideDown;
    }
    else {
        return UIInterfaceOrientationMaskPortrait;
    }
}

有点黑客,但效果很好......

我刚遇到同样的问题.James Chen的解决方案是正确的,但我最终做了一些更简单的工作 - 覆盖应用程序:supportInterfaceOrientationsForWindow在我的app委托中,如果我的rootView控制器是模态呈现MPMoviePlayerViewController则返回allButUpsideDown.不可否认,这可能并不适合所有情况,但是我不得不更改所有视图控制器:

- (NSUInteger) application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
    return [rootViewController.modalViewController isKindOfClass:MPMoviePlayerViewController.class ] ? UIInterfaceOrientationMaskAll : UIInterfaceOrientationMaskAllButUpsideDown;
}
