title: How to save response and send specific parameter in that response to server using AFN 3.0?
body: <p>I am going to use <code>AFNetworking 3.0</code>.</p>
  
  <p>On my first view when i enter mobile number and click on submit button then it send to server and get response from server, in that response, suppose i get 2 parameters ( like id:xx, token:xxxxx,).</p>
  
  <p><strong>Now my question is</strong>-</p>
  
  <p>When i get response from server then i want to go on 2nd view and when i click on login button,I want to send only token which i got from previous response(not id).How can i take only that token from previous view and send it from current view. </p>
  
  <p>I tried like this,but it not completed or not working.
  I tried to save response data like this:</p>
  
  <pre><code> NSString *str = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
   NSLog(@"responseData: %@", str);
  </code></pre>
  
  <p>and tried to send on 2nd view:</p>
  
  <pre><code> -(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
      if ([[segue identifier]isEqualToString:@"loginsegue"])
         {
           loginViewController *lvc= [segue destinationViewController];
           lvc.str=_str;
         }
   }
  </code></pre>
