title: how to check which UIButton has been selected
body: <p>I am trying to figure out which UIButton has been selected, out of a bunch, (10) buttons that are selectable and are hooked up to the same IBAction method.. however I'm not sure how to do this..</p>
  
  <p>I was woundering if there was an attribute I can set in each button that would allow me to check when getting the sender(id) back from the IBAction.. however all that gives me are the basic details of the UIButton.</p>
  
  <pre><code>&lt;UIRoundedRectButton: 0x1c576e70; frame = (20 8; 57 57); opaque = NO; autoresize = RM+BM; layer = &lt;CALayer: 0x1c5931e0&gt;&gt;
  </code></pre>
  
  <p>Also as a side note each UIButton is hooked up via an IBOutlet.. but I am not sure how I can use this to check which UIButton has just been selected... </p>
  
  <p>any help would be greatly appreciated.</p>
