Question

我的项目有 UITabbar、UınavigationBar 和 UIViewContoller。

-UITabbar
 —UINavigationController
   —UIViewController

问题：我怎样才能横向禁用一个视图控制器？我只想纵向视图，但只有一个视图。

Answer 1

disable autorotate on a single UIViewController in iOS6

将此添加到您的应用委托

- (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，它对我来说非常有效。将此代码添加到您的视图控制器中

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

并在您的viewWillAppear 添加

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

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