title: How to design a custom UIButton in a XIB file?
body: <p>I'm trying to create a custom UIButton for a Radio Button class.  When selected, the button should have a background color of orange with a text color of white, and when unselected it should have a background color of white with a text color of black.  I was able to do this programmatically by adding a colored UIView below the button's text label, but I was hoping to do this with a XIB file.  However, I can't for the life of me find an online tutorial for designing a UIButton in a XIB file.  Is there a way to do this?  Could anyone tell me how or point me to a tutorial?</p>
  
  <p>Edit: For clarity, I am using storyboards.  I'm not talking about a xib file for the entire view controller.  I'm talking about making a XIB file ONLY for the one button.  Is this possible?</p>
