title: get values of particular key in nsdictionary
body: <p>I saved the <code>json</code> parsing result in a <code>dictionary</code> which look like:</p>
  
  <pre><code>{
   "statusCode":"200",
  "body":[
    {
       "status":"success",
       "remarks":null
    }
  ],
  
  "data":[
       "abcd":[
          {
             "category":"a",
             "title":"b",
             "id":"24"
          },
          {
             "category":"c",
             "title":"crd",
             "id":"65"
          },
          {
             "category":"ds",
             "title":"sd",
             "id":"18"
          }
  
       ]
    },
    {
       "efgh":[
          {
             "category":"ds",
             "title":"sd",
             "id":"18"
          },
          {
             "category":"sd",
             "title":"sd",
             "id":"1"
          }
  
                               ]
    },
    {
       "ijkl":[
          {
             "category":"ds",
             "title":"sd",
             "id":"18"
          },
          {
             "category":"sd",
             "title":"sd",
             "id":"1"
          }
  
       ]
    }
   ]
  }
  </code></pre>
  
  <p>The data for key @"data" can be saved into an array by using </p>
  
  <pre><code>NSMutableArray *getdata=[[NSMutableArray alloc]init];
  getcat=[results objectForKey:@"data"];
  </code></pre>
  
  <p>Now what should I do for the <code>values(category, title, id)</code> inside the first index i.e. <code>"abcd"</code>.</p>
  
  <p>If anyone has any knowledge please look upon that.</p>
  
  <p>Thanks to all.</p>
