title: How to reference different UIButtons in code
body: <p>I'm building calculator on the iphone for learning purposes.</p>
  
  <p>I have a situation where I have multiple buttons that are Operations(+,-,/) and multiple buttons that are Operands e.g. 1,2,3 etc.</p>
  
  <p>So all the the Operations connect to a operationPressed method in my viewController.</p>
  
  <p>Is there a way in the UI builder to identify each UIButton other than using the Text for the button in the view?</p>
  
  <p>What would be best practice?</p>
  
  <hr>
  
  <p>Update</p>
  
  <p>What about the Identity Label that I can set in the UI builder. can I reference that?</p>
  
  <p>The reason I ask is I want to identify the button but say '/' but the text on the button would be '÷' so that is why i need some other string identifier which ultimately can be pass as an argument to my model.
