in IB how do I get a subview to stay at the same size as it's parent when I resize the parent?

Question

In Interface Builder I have one parent view and a subview under this.

I would like to have it so that when I'm working in IB if I move/change the position of the parent view, that the subview moves with it so it continues to be the same size & shape.

Is there a way to do this?

Note I'm talking about use of IB in design mode (i.e. I'm not talking about once the program is running and the ability to be able to change position etc via code)

Answer 1

In Interface Builder (IB) You need to select all the Autoresize lines. See circle in below screenshot.

Answer 2

CHeck out the AutoResizingMask.
