title: How to access data in a NSDictionary with objectForKey
body: <p>I'm trying to access the data in a dictionary. I'm able to access the data when it's a string like:</p>
  
  <pre><code>cell.textLabel.text = [[item objectForKey:@"merchant"]objectForKey:@"name"];
  </code></pre>
  
  <p>but am not sure about the syntax for an NSNumber:</p>
  
  <pre><code>NSNumber* latFromTable = [[displayItems objectAtIndex:indexPath.row]
                                             [objectForKey:@"coords"]objectForKey:@"lat"];
  </code></pre>
  
  <p>I know I'm using NSStrings in the code above which won't work. How would I change that to work with NSNumber?</p>
  
  <p>the data in the dictionary is presented as the following. The objectForKey is "coords". I want access to item 1 and 2 (lat and lng)</p>
  
  <pre><code> "coords": {
          "lat": 52.5032,
          "lng": 13.3445
  </code></pre>
  
  <p>thanks for any help.</p>
