UINavigationController for TabBar View in separate NIB

Question

Hi All,
I have a UITabBar in a Main NIB file. if I add a generic UIViewController as a sub-component of the UITabBar I can specify a NIB file, and as long as the top-level object of that NIB is a UIView, everything loads properly. However, i want to basically create a UINavigationController based NIB and have that loaded as one of the TabBar views, can anyone give me some information on how to accomplish this?
In other words, we have split up work over developers and each is going to take a few tabs of the overall application. One of the tabs uses a UINavigationController as the top level view controller. I need to know how to accomplish this with multiple NIB files.
Thanks a bunch

I had this problem as well- all views were loaded from a Tab Controller, but one I wanted a NavController to control table sub views. I finally solved it by:
Make sure in IB, all the NIB names of the tab controller buttons are set- leave one Open. This is where you can then drop in a Navigation Controller.
Set the View Mode to tree (rather than the default icon view) - this lets you see into the views.
Drop a Navigation Controller onto the grey View area of the Tab View. Set the Class of the nav controller to whatever class you created to control it with.
Now, inside the nav controller you have a view controller to drag and drop views onto.
With the View mode in IB set to Icon, it's impossible to see the relationships- this is why it's best to work in tree view.
Your tree will look something like this: (assume 4 buttons, 2nd button is the Nav Controller)

Hope it helps.
