title: Set button type
body: <p>I am creating a button programatically and I would like to know how to set that button's UIButtonType.</p>
  
  <p>This is how I am creating my button:</p>
  
  <pre><code>let headerPlusButon:UIButton = UIButton(frame: CGRectMake(5, tableView.frame.width - 30, 20, 20))
  headerPlusButon.addTarget(self, action: "paymentAddButtonTapped", forControlEvents:.TouchUpInside)
  </code></pre>
  
  <p>There is no "setButtonTypeFor..." method like how you would change the title's text and obviously this doesn't work:</p>
  
  <pre><code>headerPlusButon.buttonType = UIButtonType.ContactAdd
  </code></pre>
