title: Call method in UIViewController from NSObject?
body: <p>I'm new to iOS development so please bear with me.
  Say I have a basic method in a UIViewController that only NSLogs the words "hi".
  how would I call this method from an NSObject class?</p>
  
  <p>It's easy to call methods in an NSObject class from a ViewController but it doesn't seem to work both ways.</p>
  
  <p>I have been using the below code to call a method from an NSObject class from a view controller.</p>
  
  <pre><code> SecondClass *secondClass = [[SecondClass alloc]init];
   [secondClass displayTheNSLog];
  </code></pre>
  
  <p>but if I reverse this code so that "SecondClass" would be a View Controller the method doesent get called.</p>
  
  <p>I'm using Xcode 4.3, ARC, and storyboards.</p>
  
  <p>-Thanks for all the help!</p>
