title: Cant store int or double in dictionary
body: <p>When trying to store a double or an int in a dictionary I get an error</p>
  
  <blockquote>
    <p>error: Semantic Issue: Sending 'double' to parameter of incompatible type 'id'</p>
  </blockquote>
  
  <p>I have the following code</p>
  
  <pre><code>[data setValue:longitude forKey:@"longitude"];
  </code></pre>
  
  <p>longitude is a double.</p>
  
  <p>How should I store this? should I just create a pointer to an int or a double?</p>
