title: Find connected IBAction in Interface Builder
body: <p>I'm debugging a certain method in a pre-existing project (call it foobarPressed).  It's listed as an IBAction, but I can't figure out where in the UI to go to trigger this method, and the original developer is unavailable.</p>
  
  <p>When I open the three views associated with the controller it's in and look at the events for each button, each has something connected but none has foobarPressed.</p>
  
  <p>Is there a way to search all connections in Interface Builder?  Barring that, is there a way to search IB elements by linked identifier (so I could find the button referenced in the code as btnFoobar)?  The search field in the .xib view only seems to allow searching by name.</p>
