iid is the sender, a pointer to the control that's calling your displayvalue method. You're casting the pointer to an integer, and printing the integer result. I'm not sure exactly what you're trying to accomplish, but the fastest way to get an integer from a button to the button's action method is to store it in the tag property.

If you go into a little more detail on what you're working on, I might be able to describe the best way to model that in a Cocoa app. Also, a tip-- be sure to fix any warnings in your code before trying to figure out why something's not working! That id -> int assignment would have made the compiler complain, for example.
