Help a UITabBarController on the problem, experts give a source code example.

I'm doing a project

When first entering the interface (referred to as A interface) is with the navigation bar without TabBar's. Then click on the first interface into the second interface (referred to as B interface)
B interface is with TabBar's.

TabBar There are four options, each have an interface (referred to as C, D, E, F interface),
After this I entered the B interface TabBar will default interface displays his first C interface, while the B interface gone.

How do I modify?

I hope A display screen, click after entering the B interface, while the B interface Here are four options, are not in the selected state, I want to go into what click interface, which displays C, D, E, F interface. Then C, D, E, F interface have their own navigation bar, point and can return to the navigation bar to return to the B interface.
