title: How to check if a view controller can perform a segue
body: <p>This might be a very simple question but didn't yield any results when searching for it so here it is...</p>
  
  <p>I am trying to work out a way to check if a certain view controller can perform a segue with identifier XYZ before calling the <code>performSegueWithIdentifier:</code> method.</p>
  
  <p>Something along the lines of:</p>
  
  <pre><code>if ([self canPerformSegueWithIdentifier:@"SegueID"])
      [self performSegueWithIdentifier:@"SegueID"];
  </code></pre>
  
  <p>Possible?</p>
