title: Back/Forward Swipe Gesture in WebViews
body: <p>I've looked at another post here on Stack Overflow concerning the back gesture, but mine is a little different.</p>
  
  <p>How can I implement the swipe gesture to go 'Back' and 'Forward', to have an effect on the WebView the cursor is over? For example, if there are more than one, the gesture goes to and affects the appropriate view.</p>
  
  <p>I suppose it would be the following code, but I do not know how to get the gesture methods to work:</p>
  
  <pre><code>- (void) backGesture {
      [(WebView *)self.theWebView goBack];
  }
  
  - (void) forwardGesture {
      [(WebView *)self.theWebView goForward];
  }
  </code></pre>
  
  <p>Where 'theWebView' is the WebView the cursor is hovered over.</p>
  
  <p>Is this even possible?</p>
