title: sending a parameter argument to function through UITapGestureRecognizer selector
body: <p>I am making an app with a variable amount of views all with a TapGestureRecognizer. When the view is pressed, i currently am doing this</p>
  
  <pre><code>func addView(headline: String) {
      // ...
      let theHeadline = headline
      let tapRecognizer = UITapGestureRecognizer(target: self, action: Selector("handleTap:"))
      // ....
  }
  </code></pre>
  
  <p>but in my function "handleTap", i want to give it an additional parameter (rather than just the sender) like so</p>
  
  <pre><code>func handleTap(sender: UITapGestureRecognizer? = nil, headline: String) {
  }
  </code></pre>
  
  <p>How do i send the specific headline (which is unique to every view) as an argument to the handleTap-function?</p>
