I haven't done enough UIKit stuff to really comment on it, other than to say I also still find a lot of the conventions confusing or at least weird and also find that the documentation fails to answer my questions.

I also don't get the distinction between a UIView and a UIControllerView. In C# land I always associated view=.xaml and controller=.cs. In obj-c land both views and view controllers have a .xib and .m/.h, so it's not clear to me how responsibilities are divided.
