title: Xcode iOS push down button and drag then up on a second button
body: <p>Lets say I wan't to add 1 to an integer. This will only be done when I push down on a <code>UIButton</code> and then release my finger on another <code>UIButton</code>. <strong>A drag combo.</strong> Whats the easiest way I can make an <code>IBAction</code> occur out of a combo? This could be done with touch coordinates or maybe just <code>UIButtons</code> and <code>IBActions</code>.</p>
  
  <h2>How do I create a 2-button combo with <code>IBActions</code></h2>
