iOS does only one NavigationViewController need?

[mikezang]

I just want to know if only one NavigationViewController needs in a app?

For example, in case rootView->firstView->secondView, I thought there are two navigationViewControllers, is it correct?

In a navbar app there's only one navigation controller. Use pushViewController and maybe popViewController to show the next view controller and go back.

yes, there is only one navigation controller needed but you must add a table view (or another view) to get to the second view.
