title: Core data and saving the context in subViewControllers, ok to release?
body: <p>When updating the managedObjectContext is it ok practice to do the save setup in view controllers that may be released or should the appDelegate handle the saving of the managedObjectContext so that even if the viewController is released the save finishes?</p>
  
  <p>I'm leaning towards the idea of moving the save step into my appDelegate and having viewControllers call [appDelegate saveContext]; when an update is made, though perhaps thats moot since the viewController won't finish releasing until its done saving to CD either way...?</p>
  
  <p>For instance, is there any difference between these two actions, done from a subViewController:</p>
  
  <pre><code>[appDelegate.managedObjectContext save:&amp;error]
  </code></pre>
  
  <p>and</p>
  
  <pre><code>[appDlegate saveContext]
  </code></pre>
  
  <p>Where there is a method in appDelegate that runs [managedObjectContext save:&amp;error]</p>
  
  <p>Thanks,
  Sam</p>
