我怎么能只为一个viewController iOS做横向禁用

Question

我的项目有UITabbar，UınavigationBar和UIViewContoller。

-UITabbar
 —UINavigationController
   —UIViewController

问题：我怎么能做横向禁用一个viewController？我想只是纵向视图，但只想一个视图。

将此添加到您的应用代理

- (NSUInteger) application:(UIApplication *)application     supportedInterfaceOrientationsForWindow:(UIWindow *)window {

if ([[window.rootViewController presentedViewController] isKindOfClass:[YourViewController class]])
    return UIInterfaceOrientationMaskPortrait;
else
    return UIInterfaceOrientationMaskAllButUpsideDown;
}

我最近发现了这一点，它一直对我很有用。将此代码添加到视图控制器

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

并在viewWillAppear添加

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

    ///Disable orientation changes
    NSNumber *value = [NSNumber numberWithInt:UIInterfaceOrientationPortrait];
    [[UIDevice currentDevice] setValue:value forKey:@"orientation"];
}
