title: Convert JSON to NSArray
body: <p>I have a JSON array being output on a page. I would like to convert this JSON array into an NSArray.</p>
  
  <p><strong>This is the JSON output on the web page:</strong></p>
  
  <pre><code>[{"city":"Current Location"},{"city":"Anaheim, CA"},{"city":"Los Angeles, CA"},{"city":"San 
  Diego, CA"},{"city":"San Francisco, CA"},{"city":"Indianapolis, IN"}]
  </code></pre>
  
  <p><strong>This is my NSURL call and NSJSONSerialization:</strong></p>
  
  <pre><code>NSString *cityArrayURL = [NSString stringWithFormat:@"http://site/page.php";
  NSData *cityData = [NSData dataWithContentsOfURL:[NSURL URLWithString:cityArrayURL]];
  
  NSError *error;
  NSDictionary *cityJSON = [NSJSONSerialization JSONObjectWithData:cityData 
  options:kNilOptions error:&amp;error];
  </code></pre>
  
  <p>I would like to turn the NSDictionary called cityJSON into an NSArray. Can someone let me know what the next step might be? Thank you!</p>
