if you want multiple categories , you can follow this format

NSDictionary *jsonObject = @{
                           @"data1":@[
                              @{
                                @"title":@"A"

                                @"subData" : @[
                                @{
                                  @"title":@"aa"
                                 }]
                                }

                             ]
                         };
