Navigation controllers in a tab bar controller

What is the structure of the logic or presentation of the application with a tab bar, for example. 3 different tabs. On each tab, is there a navigation controller inside the tabs of the tab view manager?

Where are navigation controllers created and managed?

If you use NIB files, you can configure the structure of your application directly in your main NIB. The structure is as follows:

  • UITabViewController
    • UINavigationViewController
      • TabBarItem
      • UIViewController (set to download from Tab 1 View.nib)
        • NavigationItem (for the root view of the navigation controller 1 tab)
    • UINavigationViewController
      • TabBarItem
      • UIViewController ( Tab 2 View.nib)
        • NavigationItem
    • UINavigationViewController
      • TabBarItem
      • UIViewController ( Tab 3 View.nib)
        • NavigationItem
