I am laying out a calculator using Interface Builder and I ran into some issues with the layout of buttons.

I have 3 columns of number buttons, similar to most calculators, and I had no problem placing the left and right columns as the auto-layout feature of Xcode snapped them in the correct distance away from the edge of the window on the left and the operator buttons on the right; however, there was no automatic help for centering the middle column of buttons between those two.

I can eyeball it pretty well but I really prefer to have everything perfectly aligned. Is there any way to center a button between two other UI objects like this? here is a picture of the layout:

    You can place all the buttons in their own View. Place the view where you want the buttons. Then you could align the left buttons to the left of the view, align the right buttons to the right of the view, and finally center the middle buttons. Then adjust your view you made accordingly. I did something very similar. Hope this helps.
