title: Disable gesture recognizer only for a particular view
body: <p>On one view controller, I have one <code>mainView</code>. On that view I have another view, <code>sidePanel</code>, which has the frame 0,0,86,420. I have added a tap gesture recognizer. Now I want to just enable gesture recognition only for mainView and not for sidePanelView. See below image:</p>

  <p>I want to disable tapGesture for sidePanelView and enable for all areas other than it. How can I do that? (One other thing I want to say, area other than sidePanelView is parentView of sidePanelView).</p>
