title: Is there any way to attach a NSDictionary of parameters to an NSURLRequest instead of manually making a string?
body: <p><code>AFNetworking</code> allows you to add an <code>NSDictionary</code> of parameters to a request, and it will append them to the request. So if I wanted to do a <code>GET</code> request with <code>?q=8&amp;home=8888</code> I'd just making an NSDictionary like <code>@{@"q": @"8", @"home": @"8888"}</code> very simply.</p>
  
  <p>Is there a way to do this with <code>NSURLSession</code> / <code>NSURLConnection</code> / <code>NSURLRequest</code>?</p>
  
  <p>I know I can use <code>NSJSONSerialization</code> for appending JSON data, but what if I just want them as <code>GET</code> parameters in the URL? Should I just add a category?</p>
