ios - 模态 UINavigationController - 我无法停止旋转

Question

我正在使用 Storyboard，并且我在 UITabBarController 中嵌入了一个 UINavigationController。我推送一个 View Controller ，然后从这个 View Controller 我呈现一个带有 UIViewController 的 MODAL UINavigationController。

问题是，当模态视图之前的所有 View 都不能旋转时，模态视图 Controller 可以旋转。如何停止允许任何旋转的模态导航 Controller ？

我试过添加:

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

和

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

谢谢

Answer 1

尝试分类 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];
}
