title: How to access fetched property in Objective-C 2.0 using Core data
body: <p>I'm new to IPhone development and I'm currently trying my hand at Core Data. I have a couple of entities that I've defined in my model. In one entity I have a fetched property. When I generate the Objective-C source files from my model, my entity that I defined with the fetched property does not have a property defined for the fetched property. Why? How do I access the fetched property?</p>
  
  <p>More details in response to Tim:</p>
  
  <ul>
  <li>I have an entity named <code>Library</code> and another entity named <code>Book</code>. </li>
  <li><code>Library</code> has a one to many relationship to <code>Book</code> (<code>Book</code> also has an inverse relationship).</li>
  <li><code>Book</code> has a BOOL property called <code>isCheckedOut</code>. </li>
  <li>I defined a fetched property on <code>Library</code> called <code>fetchAllCheckedOutBooks</code>. The destination entity is <code>Book</code> and the predicate is <code>isCheckedOut == 1</code>.</li>
  </ul>
