How to display Navigation bar when tab bar item clicked

I m working on Iphone application which is having UITabBarController and UINavigationController

I am switch开发者_StackOverflow社区ing to UIWebView in flow of the project before which its all Native

When I switch to webview I am able to hide the Navigation bar

but when I clicked on a tab which brings it to home page I cant see navigation bar unless I select any option and go to next view

I did find out abt tabbar function

-(void) tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController

but I m not getting how to unhide or display the navigation bar again?? Please help

I guess you use

self.navigationController.navigationBarHidden = YES;

to set the navigationController's navigationBar to hidden.

If you use this in the other views in viewWillAppear you need to set it to non hidden again

self.navigationController.navigationBarHidden = NO;
