title: How to hide IBAction button created on Storyboard, on viewDidLoad?
body: <p>iOS 7, XCode 5, using Storyboards.</p>
  
  <p>I have a TableViewController.
  Inside the TVC I have 2 custom cells. One of these cells contains a button "Submit order" created on Storyboards.
  The button is added then to code as IBAction</p>
  
  <p>I can't figure out how to get a reference to the IBAction button so I can set its 'hidden' property to true.</p>
  
  <p>Any suggestions?</p>
