Can UIViewController contain more than one UIView?

Question

Can a UIViewcontroller contain more than one UIView?

Answer 1

Yes, many.

Each button, or text field or image, or ... is a view. A view controller can handle many many views. Of course, there is one view that is the parent of all others, and the view controller keeps track of that one and can then follow the tree down to handle the children (for the purposes of handling touch, or updating, etc.).

Answer 2

For clarity, NO. A UIViewController has one UIView. That UIView, like all UIViews, can contain subviews. If you want to control two views, create instance variables for each of them and add them both to your UIViewController's view variable.
