title: Using hitTest logic only for touchesBegan and NOT gesture recognizers
body: <p>I have been developing a simple game for iOS which involves dragging and using rotation- and other gesture recognizers. Dragging is realized through <code>touchesBegan/Moved/Ended</code> and rotation - through recognizer.</p>
  
  <p>The views are irregularly shaped, and the view borders sometimes overlap, so I implemented Ole Belgeman's <a href="https://github.com/ole/OBShapedButton/tree/master/UIImage+ColorAtPixel" rel="nofollow">UIImage+ColorAtPixel</a> in my <em>picture view</em> and overrode <code>isPointInside</code> method in the main <em>element view</em>. isPointInside invokes the method in <em>picture view</em>, which checks alpha at touch point and returns NO if the transparent section has been touched. Essentially, <code>hitTest</code> ignores this branch.</p>
  
  <p>But the side effect of it is that hitTest ignores all touches on the transparent section, and rotation recognizer only works on the non-transparent zone. For some views, which are too small in size, it becomes impossible to use rotation gesture :(</p>
  
  <p>Is there any way to somehow avoid this problem and use <code>hitTest</code> logic <strong>only</strong> for <code>touchesBegan</code>? I tried to work the solution out, but it seems that hitTest works strictly before any touch handling. </p>
  
  <p>Checking the transparency at <code>touchesBegan</code> works, but when you touch the transparent section, which overlaps the non-transparent section of the other view, the latter doesn't receive the touch.</p>
  
  <p>I just can't figure out the trick...</p>
  
  <p>Thank you in advance for any help!</p>
