title: setting a delegate to self's delegate?
body: <p>i have three ViewControllers; A, B, and C.</p>
  
  <p>A presents B, B presents C.</p>
  
  <p>how can i pass data from C back to A?</p>
  
  <p>i set B's delegate to A.</p>
  
  <pre><code>BViewController *bvc = [self.storyboard instantiateViewControllerWithIdentifier:@"B"];
  bvc.delegate = self;
  </code></pre>
  
  <p>Can i set C's delegate to A somehow?</p>
  
  <p>like:</p>
  
  <pre><code>CViewController *cvc = [self.storyboard instantiateViewControllerWithIdentifier:@"C"];
  cvc.delegate = (self's parent delegate)
  </code></pre>
  
  <p>?</p>
  
  <p>or do i need to set C's delegate to B, then be to A?</p>
