Modal UINavigationController - 我无法停止旋转

问题描述

我正在使用故事板，并且在 UITabBarController 中嵌入了一个 UINavigationController.我推了一个视图控制器，然后从这个视图控制器我呈现了一个带有 UIViewController 的 MODAL UINavigationController.

I am using storyboards and I have a UINavigationController embedded in a UITabBarController.i push a view controller then from this view controller I present a MODAL UINavigationController with a UIViewController.

问题是，当模态视图之前的所有视图都不能旋转时，模态视图控制器可以旋转.如何停止允许任何旋转的模态导航控制器?

The problem is, the modal view controller can rotate when all my view previous to the modal view can't.How do I stop the Modal nav controller allowing any rotation?

我尝试添加:

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

和

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

谢谢

推荐答案

尝试分类 UINavigationController

try to categories UINavigationController

@implementation UINavigationController (Rotation_IOS6)

-(BOOL)shouldAutorotate
{
    return [[self.viewControllers lastObject] shouldAutorotate];
}

-(NSUInteger)supportedInterfaceOrientations
{
    return [[self.viewControllers lastObject] supportedInterfaceOrientations];
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return [[self.viewControllers lastObject] preferredInterfaceOrientationForPresentation];
}
