TabBarController has one feature that, when you change any navigation viewcontroller title, then that title will be reflected to tabBar item.

But you should remember one thing, i.e.,

you can change the tabBarItem name by the main viewcontroller, that is refered to the specific tabBar, but not the sub ViewController.

Ex: For Pictures tab, you have given pictureViewContoroller, you can change the tabBar item name, by using that object only. you can't change by remaining view controllers or objects.
