objective c - iPhone: Add a Tab Bar controller programmatically to a navigation controller -

I am developing an iPhone application and I started with a navigation based template. But now I want to add a tap bar controller below and I want to do this without using the interface builder. Can anyone tell me how to do this? thank you in advanced!

If you are asking how to get started with the navigation controller and then the user with a tabbar Navigate to one view, I actually do it in my iPad app, go to the website listed in my profile, if you want to see how my app uses tab bar

However, The interface builder is used to complete. In the interface builder, I have created a master view with the bottom tabbar control and the above "content" UIView. Through the ideas as a user tab, the "content" view is programmatically assigned to that view, which the user is interested.

I think you can fulfill it without even IB. Simply use the code:

  UITabBar * aTabbar = [UITabBar alloc] init]; [[See your self] Adsview: Atibber];   
 Of course, you would like to create tab bar items and assign visual controller to each item. You may also need to zoom the layout parameters of the tab bar control so that it sits beneath the view.
