title: RestKit: "article" & "articles" keyPaths - do I need 2 different descriptors?
body: <p>I can get single "article" or an array of "articles". Mapping is the same. But <code>keyPath</code> will be "article" or "articles". Do I need 2 different descriptors? Or can I combine it into one somehow? (as an example - Ruby on Rails can recognize single-multiple automatically).</p>
  
  <p>Currently I'm doing it separately, <strong>Single</strong>:</p>
  
  <pre><code>RKResponseDescriptor *articleDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:articleMapping method:RKRequestMethodAny pathPattern:nil keyPath:@"article" statusCodes:statusCodes];
  [_manager addResponseDescriptor:articleDescriptor];
  </code></pre>
  
  <p><strong>Multiple:</strong></p>
  
  <pre><code>RKResponseDescriptor *articlesArrayDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:articleMapping method:RKRequestMethodAny pathPattern:nil keyPath:@"articles" statusCodes:statusCodes];
  [_manager addResponseDescriptor:articlesArrayDescriptor];
  </code></pre>
