title: Animate Longpress on UITableViewCell with background Color
body: <p>I want to animate my UITableViewCell on Longpress. </p>
  
  <p>When a user starts holding on a cell it should get a light green colour - after holding on the cell the colour should get more intense to a dark green and then fire a event and the <code>Longpressgesture</code> is done.</p>
  
  <p>This is my normal Longpress Recognizer</p>
  
  <pre><code>// In the viewDidLoad
      var longPress = UILongPressGestureRecognizer(target: self, action: "respondToLPGesture:")
  
      longPress.minimumPressDuration = 2;
  
  
  func respondToLPGesture(gesture: UIGestureRecognizer) {
  
      if(gesture.state == UIGestureRecognizerState.Began) {
  
      }
  }
  </code></pre>
  
  <p>Do I need to set the minimumPressDuration to 0.1 seconds and then add a additional waiting Time? Or how can I handle that in swift? Thanks</p>
