Objective-C

Is this:
[[[UIApplication sharedApplication] keyWindow] addSubview:navView.view];

the best way to add a UINavigationController to the view hierarchy from inside a UIViewController. It seems a little odd OOP-wise. Also I can't seem to figure out how to do a UIView animation when switching the views because I'm not adding or removing a subview from the UIViewController that is calling this.

What the hell did I just avoid digesting?

Objective-C(and smalltalk): when you are stupid enough to forget arguments of a "function".
