title: how can I identify a uibutton with the same tag id
body: <p>I'm looping through an array and im using the index to tag my button id but there is a 1% chance two button tag id's can be the same when calling them.  How can I differentiate the two buttons when trying to call one of them with the same tag id?</p>
  
  <pre><code> let tmpButton = self.view.viewWithTag(MyVariables.SelectedChatLike) as! UIButton
   let path = NSBundle.mainBundle().pathForResource("myImage.gif", ofType: nil)
   tmpButton.setImage(UIImage(contentsOfFile: path!), forState: UIControlState.Normal)
  </code></pre>
  
  <p>sometimes the code above changes the wrong button image because two tags can be the same </p>
