问题
I'm trying to follow this tutorial here to recreate a custom center tab button, but I already have my tabbarcontroller setup in IB. Can anyone help me do this? The tutorial does it all through code so its difficult to follow.

回答1:
All they're doing is creating a blank UITabBarItem, no image or name, simply a placeholder. They then put a UIButton with a custom image (i.e. the green camera button) on top of the UITabBar. Just go into interface builder and add a new TabBarItem and put a UIButton on top of it.
