Places where pure code is not difficult, we'll go that route because its noticeably faster. While its gotten better in iPhone OS 3.0+, I can say that there have been a few places where using a NIB creates a non-smooth experience whereas using pure code is smooth as butter. And this is borne out in tech talks and WWDC recommendations.

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?
