title: Multiple delegates per one object?
body: <p>I have a <code>UIScrollView</code> that I need to subclass and within the subclass I need to attach the <code>UIScrollViewDelegate</code> so I can implement the <code>viewForZoomingInScrollView</code> method. </p>
  
  <p>Then I have a <code>UIViewController</code> where I need to instantiate an object of this <code>UIScrollView</code> subclass that I created, and I would also like to make the UIViewController a <code>UIScrollViewDelegate</code> for this object so I can implement <code>scrollViewDidZoom</code> in this <code>UIViewController</code> class. </p>
  
  <p>How is it possible to make one object have two delegates? (I know I could easily just have one delegate and just implement both methods there, but for design purposes I'd like to do it the way that I'm mentioning). </p>
