title: How to share one storyboard scene between multiple UIViewControllers
body: <p>I'm completely re-formulating this question having learned that I was originally off track but that having me no closer to solving the problem. With reference to this image...
  <img src="https://i.stack.imgur.com/TSnYS.png" alt="storyboard illustration"></p>
  
  <p>I am wanting to either create or manipulate the segue (highlighted in yellow) in code such that the Master view is any one of a number of subclasses of <code>MFMasterViewController</code> (highlighted in red).</p>
  
  <p>When doing this using Nibs I could create a Nib, <code>SharedNib.xib</code> &amp; set the class as <code>MFMasterViewController</code>, then create my subclasses, say <code>MFMasterViewControllerSubclassA</code>, <code>MFMasterViewControllerSubclassB</code> etc. &amp; then instantiate whichever subclass I wanted using...</p>
  
  <pre><code>MFMasterViewControllerSubclassA *controller = [[MFMasterViewControllerSubclassA alloc] initWithNibName:@"SharedNib" bundle:nil];
  </code></pre>
  
  <p>or...</p>
  
  <pre><code>MFMasterViewControllerSubclassB *controller = [[MFMasterViewControllerSubclassB alloc] initWithNibName:@"SharedNib" bundle:nil];
  </code></pre>
  
  <p>etc.</p>
  
  <p>Any clues as to how I can get this right using storyboards?</p>
  
  <p>In my case the reason for wanting to do this is that all my subclasses are the same tableview &amp; data but sorted differently &amp; having some difference in what's written to the detail text of the cels. I suspect that it is a not uncommon pattern.</p>
  
  <p>Cheers &amp; TIA,
  Pedro :)</p>
