title: cocos2d 3.0 how to handle touch swallowing with priority
body: <p>Since CCTargetedTouchDelegate has been removed since cocos2d 3.0, I would like to know how can i handle touch swallowing stuff? </p>
  
  <p>I have a small sprite on top of a canvas node(layer in 2.x) and need to set the priority of the sprite higher than the canvas. When a user touches within the sprites bounding box, the touch is swallowed, otherwise the canvas will respond to it. </p>
