But it seems that in this case I can't use my UINavigationBar subclass if I instantiate a Navigation Controller programmatically, so the only way to use my UINavigationBar subclass is to instantiate a Navigation Controller in IB otherwise I can't change UINavigationBar class/instance, this makes sense? I'm forced to use IB?
