title: iOS - Gesture Recognizer translationInView
body: <p>I use the following line of code in a pan gesture recognizer:</p>
  
  <pre><code>CGPoint translation = [sender translationInView:self.view];
  </code></pre>
  
  <p>If I move the associated processing to a long press gesture recognizer, there is not a translationInView method.  </p>
  
  <p>My question is, how can I get the same value for translation if using the long-press recognizer?</p>
  
  <p>Thanks</p>
