how to create json in objective-c

Question

NSData* jsonDataToSendTheServer;

NSDictionary *setUser = [NSDictionary
            dictionaryWithObjectsAndKeys:[@"u" stringByAppendingString:my.id],@"id",
                                        @"GET_USER_INFO",@"command",
                                        @"",@"value",
                                        nil];

 NSLog(@"%@", jsonDataToSendTheServer);

Here is my code. When I run above code I get this print

<7b226964 223a2275 35383738 37373334 31222c22 636f6d6d 616e6422 3a224745 545f5553 45525f49 4e464f22 2c227661 6c756522 3a22227d>

I don't have any idea whether I can created a json or not.

How can I fix this?

NSDictionary *jsonObject = @{
                                 @"a":@[
                @{
                                             @"title1”:@“AA”,
                                             @"title2” : @“BB”,
                                             @"subcats" : @[
                                                     @{
                                                         @"title1” : @“CC”,
                                                         @"title2” :@“DD”
                                                         }

                                                     ]

                                             }
                                         ]



                                 };
