title: Sorting NSDictionary
body: <p>I was wondering if someone can show me how to sort an <code>NSDictionary</code>; I want to read it starting from the last entry, since the key is Date + Time and I want to be able to append it to an <code>NSMutableString</code>. I was able to read it using an enumerator but I don't get the results I want.</p>
  
  <p>Thanks</p>
