shouldAutorotate，supportedInterfaceOrientations和preferredInterfaceOrientationForPresentation在iOS 7中无法正常工作

问题描述

我在尝试阻止某些视图中的方向时遇到问题，但代码不是工作属性。

I'm having problems trying to block the orientations in some views, but the code is not working property.

我在每个视图中使用这些行：

I'm using this lines in every view:

- (BOOL)shouldAutorotate
{
    return YES;
}

- (NSUInteger)supportedInterfaceOrientations
{
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
        return UIInterfaceOrientationMaskPortrait;
    } else {
        return UIInterfaceOrientationMaskAll;
    }
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationPortrait;
}

它几乎可以在使用UINavigationController的视图中工作，但在那些视图中使用UITabBarController是我遇到大问题的地方，因为它接缝代码没有被调用。

It almost work in the views that are using the UINavigationController, but in the ones that use the UITabBarController is where i'm having big problems, because it seams that the code is not been called.

推荐答案

Ok我解决了，你必须继承UINavigationController和UITabBarController的子类，所以这里是代码：

Ok I solve it, you have to subclass UINavigationController and UITabBarController, so here is the code:

//cCustomNavigationController.h file

#import <UIKit/UIKit.h>

@interface cCustomNavigationController : UINavigationController <UINavigationControllerDelegate>

@end

//cCustomNavigationController.m file

#import "cCustomNavigationController.h"

@interface cCustomNavigationController ()

@end

@implementation cCustomNavigationController

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

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

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

@end

//cCustomTabController.h file

#import <UIKit/UIKit.h>

@interface cCustomTabController : UITabBarController <UITabBarControllerDelegate>

@end

//cCustomTabController.m file

#import "cCustomTabController.h"

@interface cCustomTabController  ()

@end

@implementation cCustomTabController

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

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

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

@end

现在你只需要创建您的TabBarController或您的NavigationController使用此类，无论您需要它，即

now you just have to create your TabBarController or your NavigationController using this classes where ever you need it i.e.

//For the UINavigationController
UINavigationController *navigationController = [[cCustomNavigationController alloc] init];

//For the UITabBarController
UITabBarController *tabController = [[cCustomTabController alloc] init];

我希望这能帮到你们。
