title: Core Data - Basic Questions
body: <p>I would like to know how the following works in Objective-C</p>
  
  <ol>
  <li><p>in my header file i have the following which is initialized from a different view controller</p>
  
  <pre><code>@interface UserLookup : UIViewController {
      NSManagedObjectContext *referringObject;
  }
  </code></pre></li>
  </ol>
  
  <p>and in my implementation file i have to pass this <code>NSManagedObjectContext</code> to 2 child view controller then does it make a difference which view controller is called first... and does the <code>NSManagedObjectContext</code> changes in any one of the child controller?</p>
  
  <p>Regards</p>
