Navigation bar not displaying

Question

In a tab bar based app, I add a new UIViewController from tabview1 like this

[self.view addSubview:self.aView.view];

I created the nib for aView in IB. It is a view with a tableview and navigation bar. I have aView and bView, which are nearly the same and added to the parent the same way. The only difference is that aView has two sections in its tableview. Otherwise, the views are laid out the same.

For some reason, aView does not display its navigation bar. It also seems to sit a little higher than bView, since I can see a sliver of the parent view between the tab bar and aView. I've tried to find any differences between these two views that would cause this behavior but can't. What am I overlooking?

Depending on your needs you should be able to create separate nib's for each UIViewController then set each of these nib's to be loaded as the first view controller in each tar of the tabbar, or with the same nib's set these in each bar with:

- (void)setViewControllers:(NSArray *)viewControllers animated:(BOOL)animated
