How to access to navigationItem when I am in a view controller in tabBar?

Question

I have view controllers in a tabBar. And the tabBar is in navigationController. I want to access to navigationItem when I am in a view controller in tabBar. Usually, when I set a navigationItem's title, I used to doing this. (if I am in a viewController)

[ [ self navigationItem ] setTitle: @"Menu" ];

But I am in a view controller in tabBar in navigation controller, this way doesn't work.

A view controller has a navigationItem property. But, although view controllers in tabBar has a navigationItem property, that doesn't work. I think that it is right logically.

Thank you for reading my question.

obviously if its a view, you can consider adding a label as a subview to show title, if thats your question. — humblePilgrim, Mar 28 '11 at 06:30

In viewWillAppear method in view controller, I wrote '[ [ [ self tabBarController ] navigationItem ] setTitle: @"Menu" ];' Whenever a view appear, tabBar's navigationItem's title was set. Though this way don't slide the title text on title bar (animation), it work. — MonsterK, Mar 28 '11 at 10:38

Assuming your view controller hierarchy looks like

> UINavigationController
   > UITabBarController
      > CustomViewController (CVC)

Controllers in a tab bar controller hold a reference to this controller via the tabBarController property.

In CVC, you can access the navigation item like this: self.tabBarController.navigationItem.
