推荐答案

步骤1.创建UINavigationcontroller的子类，命名为CustomNavController 步骤2.在AppdDelegate中初始化CustomNavController而不是UINavigationController.

Step 1. Create a subclass of UINavigationcontroller named like CustomNavController Step 2. initialise CustomNavController instead of UINavigationController in AppdDelegate.

第3步.在CustomNavController中重写UINavigationController的以下方法

Step 3. override following method of UINavigationController in CustomNavController

-(NSUInteger) supportedInterfaceOrientations
{

    if([NSStringFromClass([[[self viewControllers] lastObject] class]) isEqualToString:@"ViewAsset"]){
        return UIInterfaceOrientationMaskAll;
    }

    return UIInterfaceOrientationMaskPortrait;
}

-(BOOL)shouldAutorotate
{
    return YES;
}

其中ViewAsset是在两种模式下都需要的类的名称.

where ViewAsset is name of class which you need in both mode.
