How to output frame positions in debugger?

Question

I have a UIIMageView and want to output values such as:

• myobject.center.y
• myobject.frame

Basically, position and size information. I'm using both "po" in the console and breakpoint actions with @@ but neither works. I always end up with an error such as "There is no member named center". How do I output these values in both the debugger console and through breakpoint actions?

Also, is it possible to have the frame outline draw itself so I can see it in the view?

In my experience, GDB doesn't work with the dot syntax for properties. You need to use [myobject center].y or [myobject frame] instead. Also, since neither CGFloat nor CGRect are objects you need to use "p" instead of "po".
