title: Double Tap for certain part of view
body: <p>I am bit stacked with a functionality that should perform a certain task after double taping on a certain place on UIView. I know how to count number of taps, but do not know how to determinate which place has been tapped and I guess to compare with CGRect of view which was specified for doing this action.</p>
  
  <p>thanx in advance  </p>
