title: Calling a public method
body: <p>I'm trying to figure out how to centralize a method that I use in a few of my ViewControllers.  I already had a singleton that I was using for some variables.  I called the singleton class Shared.</p>
  
  <p>I moved my method to the Shared class and tried calling it like so:</p>
  
  <pre><code>m.createdAt = [Shared getUTCFormateDate:[messageObject objectForKey:@"created_at"]];
  </code></pre>
  
  <p>It's giving me an exception saying that the selector doesn't exist when it tries to call it.</p>
  
  <p>I have already imported Shared.h.  Any other thoughts would be appreciated.</p>
