iOS 6：将视图控制器推入导航控制器堆栈时如何强制更改方向 [英] iOS 6: how to force change orientation when pushing view controller into the navigation controller stack

问题描述

我认为这个问题现在应该被问过一百万次，但我仍然无法找到答案。

I think this question should've been asked a million times by now, but I still can't find an answer to this.

这是我的层次结构：UINavigationController - > UIViewController 1 - >（push） - > UIViewController 2

Here's my hierarchy: UINavigationController -> UIViewController 1 ->(push)-> UIViewController 2

UINavigationController：支持所有可能的方向
UIViewController 1：仅支持portrait
UIViewController 2 ：仅支持横向

UINavigationController: supports all possible orientation UIViewController 1: supports only portrait UIViewController 2: supports only landscape

如何仅将UIViewController 1锁定为纵向，同时仅将UIViewController 2锁定为横向？它甚至可能吗？到目前为止，我看到的是UIViewController 2始终采用UIViewController 1的方向。

How can I lock UIViewController 1 into portrait only and at the same time lock UIViewController 2 into landscape only? Is it even possible? So far what I see is that UIViewController 2 always takes the orientation of UIViewController 1.

注意，这仅适用于iOS 6。

Note, that this is for iOS 6 only.

谢谢！

推荐答案

我也发现同样的问题。我发现shouldAutorotate函数没有调用每次所以我改变方向程序

I am also find the same problem.i have found that shouldAutorotate function not call every time so i change orientation programmatic

首先导入此

#import <objc/message.h>

然后

-(void)viewDidAppear:(BOOL)animated
{

     if(UIDeviceOrientationIsPortrait(self.interfaceOrientation)){
        if ([[UIDevice currentDevice] respondsToSelector:@selector(setOrientation:)])
        {
            objc_msgSend([UIDevice currentDevice], @selector(setOrientation:), UIInterfaceOrientationLandscapeLeft );


        }
    }

}

希望这对你有帮助。
