Question of XCode app development: How to create a dial pad for phone call?

Currently I am working on phone call app on iPhone but can't find a reusable UI for the dial pad as the one built-in on iPhone. It's dirty to layout the UI 开发者_开发技巧and sound for each and I would like to know does anyone have such experience?

Thanks in advance.
