title: Is it possible to check if a UI element has a certain reference outlet?
body: <p>I'm writing unit tests to find if elements exist on a certain nib. For example, I want to loop through a nibs views and check if one exists with a referencing outlet 'commentTextView', to check if that text view exists.</p>
  
  <p>Right now, I only see methods to check if a target exists (like checking if a button will call a certain selector when it is clicked), but not to check what I need.</p>
