How do you specify a really large character in UIButton?

Question

I have a series of buttons that have suit symbols on them. Currently I provide these suit symbols as bitmaps. In preparation for iPhone 4 I'd like to use text instead. However Interface Builder rescales the button to account for whitespace underneath the symbol so I can't get the image to fill the button completely.

Any hints on getting Interface Builder to behave?

Answer 1

Use transparent suit symbols that are all the same size such as Crystal Clear icons.
