I have a question about the organization of the tab bar item. Why does it live in the UIViewControlle? Presumably most view controllers aren’t in a UITabBarController. Semantically, wouldn’t it make more sense for a UITabBarController to have a collection of UITabBarItems corresponding to its child controllers? In the future, if Apple adds other view navigators like UITabBarController (for the sake of example let’s call it UIViewSwitcherController), would they need to add a viewSwitcherItem instance variable to the UIViewController?
I understand how the existing paradigm works, I just don’t get why it would be arranged this way. I’m hoping someone can shed some light on it.
