title: How to Implement Swipe Gesture in Down Direction for UITableView?
body: <p>I tried the following code:</p>
  
  <pre><code>UISwipeGestureRecognizer *showBar = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(gestureShowBar:)];
  showBar.direction = UISwipeGestureRecognizerDirectionDown;
  showBar.numberOfTouchesRequired = 2;
  [self.tableview addGestureRecognizer:showBar];
  </code></pre>
  
  <p>with no luck! The tableview tends to scroll when I swipe is performed using two fingers. So, I tried disabling multi-touch on tableview and let the superview handle the gesture:</p>
  
  <pre><code>UISwipeGestureRecognizer *showBar = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(gestureShowBar:)];
  showBar.direction = UISwipeGestureRecognizerDirectionDown;
  showBar.numberOfTouchesRequired = 2;
  [self.view addGestureRecognizer:showBar];
  </code></pre>
  
  <p>Again, it doesn't work! I really wonder why a tableview will respond to two finger swipe although multi-touch is not enabled!</p>
