I'm new to iphone development.

I've read tutorials about implementing a tab bar controller on the window (eg as the main controller for the app). But how can I create a tab bar controller as a 'standalone' UIViewController that can be called by a navigation bar controller?

Basically my navigation bar controller has an array of UIViewControllers that it displays in the table and then loads the appropriate view/controller when a user selects an item.

Now I want one of these loaded views/controllers to be a tab bar controller. How can I do this?

I'm not sure how to create a tab bar controller on its own without having an outlet/instance in the application delegate.

Hope that made sense. Thanks.
