我的应用程序包含以横向和纵向模式播放视频的功能。视频可以是 youtube，在 iOS 7 之前一切正常，但现在 youtube 视频在 iOS 8 上无法以横向模式工作。
我的代码:
- (NSUInteger)application:(UIApplication *)applicationsupportedInterfaceOrientationsForWindow:(UIWindow *)window {
if ([[window.rootViewController presentedViewController]
isKindOfClass:[MPMoviePlayerViewController class]] || [[window.rootViewController presentedViewController] isKindOfClass:NSClassFromString(@"MPInlineVideoFullscreenViewController")]) {
return UIInterfaceOrientationMaskAllButUpsideDown;
} else {
if ([[window.rootViewController presentedViewController]
isKindOfClass:[UINavigationController class]]) {
// look for it inside UINavigationController
UINavigationController *nc = (UINavigationController *)[window.rootViewController presentedViewController];
// is at the top?
if ([nc.topViewController isKindOfClass:[MPMoviePlayerViewController class]]) {
return UIInterfaceOrientationMaskAllButUpsideDown;
// or it's presented from the top?
} else if ([[nc.topViewController presentedViewController]
isKindOfClass:[MPMoviePlayerViewController class]]) {
return UIInterfaceOrientationMaskAllButUpsideDown;
}
}
}
return UIInterfaceOrientationMaskPortrait;
}
在 iOS 7 之前一切正常，但在 iOS 8 上停止工作。 任何帮助表示赞赏
最佳答案
虽然回答自己的问题有时很愚蠢，但有助于帮助面临同样问题的其他人。
在 iOS 8 中，我们需要检查 AVFullScreenViewController 而不是检查 MPInlineVideoFullscreenViewController。下面是适用于所有 iOS 版本(即 iOS 8 及更低版本)的完整方法。
- (NSUInteger)application:(UIApplication *)applicationsupportedInterfaceOrientationsForWindow:(UIWindow *)window {
if ([[window.rootViewController presentedViewController]
isKindOfClass:[MPMoviePlayerViewController class]] || [[window.rootViewController presentedViewController] isKindOfClass:NSClassFromString(@"MPInlineVideoFullscreenViewController")] || [[window.rootViewController presentedViewController] isKindOfClass:NSClassFromString(@"AVFullScreenViewController")]) {
return UIInterfaceOrientationMaskAllButUpsideDown;
}else {
if ([[window.rootViewController presentedViewController]
isKindOfClass:[UINavigationController class]]) {
// look for it inside UINavigationController
UINavigationController *nc = (UINavigationController *)[window.rootViewController presentedViewController];
// is at the top?
if ([nc.topViewController isKindOfClass:[MPMoviePlayerViewController class]]) {
return UIInterfaceOrientationMaskAllButUpsideDown;
// or it's presented from the top?
} else if ([[nc.topViewController presentedViewController]
isKindOfClass:[MPMoviePlayerViewController class]]) {
return UIInterfaceOrientationMaskAllButUpsideDown;
}
}
}
return UIInterfaceOrientationMaskPortrait;
}
更新: 也适用于 iOS 9
