title: Swift 2.0 beta trying to make UITextview be able to be dragged
body: <p>I got this error message: &quot;-[UITextView labelDragged:]: unrecognized selector sent to instance 0x7a2bf400&quot;
  Here is my code:<br></p>
  <pre><code>var upperText:UITextView = UITextView()
   var lowerText:UITextView = UITextView()
  private func addGestureRecognizers(){  
         let drag1 = UIPanGestureRecognizer(target: upperText,action: Selector(&quot;labelDragged:&quot;))
          let drag2 = UIPanGestureRecognizer(target: lowerText, action: Selector(&quot;labelDragged:&quot;))
          view.addGestureRecognizer(drag1)
          view.addGestureRecognizer(drag2)
      }
  func  labelDragged(sender : AnyObject?) {
          let gesture:UIPanGestureRecognizer = sender as! UIPanGestureRecognizer
          let textView:UITextView = gesture.view as! UITextView
          let translation:CGPoint = gesture.translationInView(textView)
          textView.center = CGPointMake(textView.center.x, textView.center.y + translation.y)
          gesture.setTranslation(CGPointZero, inView: textView)
      }
  </code></pre>
