title: How to extract "key" values from NSDictionary
body: <p>I have an object that returns the following using <code>id *value = [arg1 valueForKey:@"value"];</code>:</p>
  
  <pre><code>value = {
     "item_id" = 1234;
     "item_type" = text;
     turn = 4;
  }
  </code></pre>
  
  <p>I used <code>NSLog(@"%@", NSStringFromClass([value class]))</code> to return the object type which is <code>__NCSFDictionary</code>.</p>
  
  <p>I want the value of turn in value, so I used:</p>
  
  <pre><code>id *turn = [value valueForKey:@"turn"];
  </code></pre>
  
  <p>but it's returning nil.</p>
  
  <p>Any idea on what I'm doing wrong?</p>
  
  <p>Thanks</p>
