title: Creating a NSMutableArray from a NSArray Objective-C
body: <p>I have an NSArray that gives me the following data:</p>
  
  <pre><code>01/14/2013 13:28:06.559 IUser Reader [71164: c07] (
           {
           "id_acompanhante" = "";
           "id_evento" = 34;
           "user_id" = 1;
           "inserido_por" = "Himself";
           name = iUser;
           status = done;
           type = User;
       }
           {
           "id_acompanhante" = 1;
           "id_evento" = 34;
           "user_id" = 1;
           "inserido_por" = iUser;
           name = "Mayara Roca";
           status = naofeito;
           type = companion;
       }
  )
  </code></pre>
  
  <p>How do I play this data to a NSMutableArray and add another field within each item. example:</p>
  
  <pre><code>  {
       "id_acompanhante" = "";
       "id_evento" = 34;
       "user_id" = 1;
       "inserido_por" = "Himself";
       name = IUser;
       status = done;
       type = User;
       tag = 2;
   }
  </code></pre>
  
  <p>I added one more field "TAG".</p>
  
  <p>How do I do this?</p>
