title: How to track how many times a UIButton has been pressed?
body: <p>I need to know how many times a button in my program has been pressed. I tried making a category of <code>UIButton</code> and adding properties to it so that each time a button is pressed I would say <code>sender.someproperty++;</code> but the compiler complains when I add properties to a category.</p>
  
  <p>Any way I can track this? I wish every object in Xcode had a random <code>unassigned integer property</code> that you could randomly assign it different values to keep track of each object </p>
  
  <p>the first time I press the button, I want something to happen, the second time, I want something else to happen, the third time, I want something else to happen, and then the fourth time I want it to default so its like I'm pressing it the first time.</p>
