title: Set value of a NSDictionary in a NSDictionary
body: <p>I have a dictionary as the value for another dictionary:</p>
  
  <pre><code>10 = {
          createdate = "2012-03-20 15:04:09.125177-05";
       }
  </code></pre>
  
  <p>I would like to set a value to the inner dictionary without having to pull it out, but</p>
  
  <pre><code>[NSDicionary setObject:forKey:]
  </code></pre>
  
  <p>only goes one deep. can I add another key to that? I tried</p>
  
  <pre><code>[[NSDicionary setObject:forKey:]forKey:]
  </code></pre>
  
  <p>but xCode didn't like that.</p>
  
  <p>Any ideas?</p>
