title: userInteractionEnabled isn't disabling touch events
body: <p>I am trying to disable touch events for my game's UIView, but setting <code>userInteractionEnabled = NO</code> doesn't seem to have any effect.  This is the only view I have in the App.</p>
  
  <p>If I check <code>isUserInteractionEnabled</code> for the view, it returns NO.</p>
  
  <p>I am getting my <code>-(void)touchesBegan:(NSSet*)touches withEvent:(UIEvent*)event</code> messages via my UIViewController, not the UIView.  Since adding a root UIViewController, I no longer get touch events sent to the UIView.</p>
  
  <p>Am I doing something wrong here?  I would assume setting <code>userInteractionEnabled = NO</code> would stop all touch events from happening. </p>
