Question

If we use Interface Builder to edit the content in the view, then how do we add a drawRect to that UIView object? (Probably we want a new class FooView that subclasses UIView — but how will the .xib content be placed on this view?)

Answer 1

Adding “content” to the view controller’s view in the xib just involves adding subviews – these are not affected by drawRect:.

That said, to set a custom class as the main view property of a view controller, just select the view in the xib, go to the identity inspector, and change the class from UIView to your custom class.
