问题描述

请帮我在根视图中隐藏导航控制器.我找到了在所需的每个视图控制器中写入[navigationController setNavigationBarHidden:YES]的解决方案.好吧，它只能在第一次使用:我运行应用程序，在根视图中没有导航，然后转到第二个视图–导航出现，确定.但是，然后我在导航控制器中按了返回"，并且从根视图进行的导航还没有消失.我在xib上工作.

Please, help me to hide navigation controller in root view. I've found the solution to write [navigationController setNavigationBarHidden:YES] in every view controller which I need. Well, it works but only for the first time: I run application, in root view I don't have navigation, then I go to the second view – the navigation appears, OK. But then I press "Back" in navigation controller, and navigation from root view hasn't disappear. I work with xib.

推荐答案

在rootViewController中

In rootViewController

-(void)viewWillAppear:(BOOL)animated
{
     [self.navigationController setNavigationBarHidden:YES animated:NO];
}

在第二个视图中(在rootViewController旁边)

In second View(next to rootViewController)

-(void)viewDidLoad:(BOOL)animated
 {
    [self.navigationController setNavigationBarHidden:NO animated:NO];
 }
