title: Best way to pass data from Child Modal VC to the Parent View Controller?
body: <p>What is the best way to pass data from a child modal view to the parent view controller?</p>
  
  <p>I have a Child Modal Login Screen on my iPad app that I want to pass back user information to the parent Split View Controller.</p>
  
  <p>I am thinking of using NSNotification, but I am not sure if this is the easiest/most efficient way to pass data back to the parent.</p>
  
  <p>Thanks!
