title: How to cancel touchesMoved:withEvent:
body: <p>I have a query regarding touches on the view:</p>
  
  <p>I have a parentView(frame is (0,0,768,1024)) which contains two subViews(A and B),A frame (0,0,512,768) with tag 100 and B Frame (512,0,512,768) with tag 200.</p>
  
  <p>I implemented touches methods <code>touchesBegan:withEvent:</code>  <code>touchesMoved:withEvent:</code>  <code>touchesEnded:withEvent:</code>. </p>
  
  <p>When I started touch from A to B <code>touchesBegan</code> and <code>touchesMoved</code> methods gets fired as expected </p>
  
  <p><strong>I need to implement:</strong> As the touches reaches B from A, touchesEnded of A should get fired and touches began of B be fired and vice versa .I have my own logic in their respective methods.Can some one suggest how to achieve the same.</p>
