Hi.

I created CustomNavBar subclassing UINavigationBar.

In Interface Builder I drag a Navigation Controller (UINavigationController) 
from the library to the document. Under this object in document window I can 
see a Navigation Bar (UINavigationBar). Clicking it and using the Identity 
Inspector I can change the class from standard UINavigationBar to my 
CustomNavBar.

How can I reproduce it programmatically?

        MyViewController *myViewController = [[MyViewController alloc] init];
        UINavigationController *navController = [[UINavigationController alloc] 
initWithRootViewController:myViewController];
        [myViewController release];

UINavigationController navigationBar property is read only so I can't do:

        CustomNavBar *customNavBar = [[CustomNavBar alloc] init];
        navController.navigationBar = customNavBar;
        [customNavBar release];

What should I do to customize the navigation bar programmatically? Is IB more 
"powerful" than "code"? I believed all that can be done in IB could be done 
also programmatically.

Duccio.
