So, just to understand, why can I do that through IB but not (legally) via code? The ability to choose a class for the navigation bar in a navigation controller should have been blocked in IB?
You says about change Navigation Bar class to my subclass in IB "recommend avoiding even using this approach in IB", why? Should I read this in documentation or I would have inferred by readonly navigationBar property (because next time I would not ask the list similar question/problem)?
I started working with Cocoa Touch a few days ago and I will not only learn the techniques but also best practices, philosophy and so on...
