title: "Save" in CoreData-apps
body: <p>I've here a CoreData app (no document-based), 1 entity and 1 tableview for edit/add/remove "instances" of the entity. Now I can manual add and save but I would like to</p>
  
  <blockquote>
    <p><code>a)</code> save automaticly changes<br>
    <code>b</code>) add automaticly some "instances" with the first start.</p>
  </blockquote>
  
  <p>I think <code>a)</code> can be solved with NSNotifications. But which to use by entities?</p>
  
  <p>Any ideas how to solve <code>a)</code> or <code>b)</code>?</p>
  
  <p>Thanks for <code>every</code> answer. =)</p>
