iOS-仅在视频上允许横向模式 [英] iOS - Allow Landscape mode on videos only

问题描述

我的整个应用中都有视频.一些使用MPMoviePlayerController，其他使用带有YouTube的UIWebView.我希望我的应用程序完全是纵向的.但是，我想让用户可以选择在有视频时翻转到风景(不是强制，而是可选).

I have videos throughout my app. Some using MPMoviePlayerController, others in a UIWebView with YouTube. I want my app to be totally portrait. However, I want to give the user the option to flip to landscape when there's a video (not force, but optional).

我一直在网上寻找答案，但是还没有发现任何东西.

I've been searching the web for an answer, but I haven't found anything yet.

感谢您的帮助！

推荐答案

我遇到了相同的问题，并通过在我的应用程序委托中添加了此问题进行了修复，基本上只允许在MPMoviePlayerViewController的子类上进行横向定向:

I had the same issue and fixed it by adding this in my app delegate, basically allowing Landscape orientation only on subclasses of MPMoviePlayerViewController:

#import <MediaPlayer/MediaPlayer.h>

@implementation UIViewController (orientationFix)

-(NSUInteger) supportedInterfaceOrientations
{
    if ([[self class] isSubclassOfClass:[MPMoviePlayerViewController class]]) {
        return UIInterfaceOrientationMaskLandscape;
    }
    return UIInterfaceOrientationMaskPortrait;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    if ([[self class] isSubclassOfClass:[MPMoviePlayerViewController class]]) {
        return UIInterfaceOrientationLandscapeLeft | UIInterfaceOrientationLandscapeRight;
    }
    return UIInterfaceOrientationPortrait;
}

@end

@implementation MyAppDelegate

@end
