        id = 0;
    },
        {
        Name = "PREMIER DIM OUT";
        id = 10;
    },
        {
        Name = "PRADO COLLECTION";
        id = 15;
    },
        {
        Name = "PURE WALLS 6";
        id = 16;
    },
        {
        Name = PLATINA;
        id = 17;
    },
        {
        Name = "SARMASIK LEATHER";
        id = 19;
    },
        {
        Name = "PICASA COLLECTION";
        id = 21;
    },
        {
        Name = "3PASS BLACK OUT-SLOT LOT";
        id = 25;
    },
        {
        Name = ABYSS;
        id = 26;
    },
        {
        Name = ABYSSION;
        id = 27;
    },
        {
        Name = "ACC BOOK MODERN ELEMENT 2";
        id = 28;
    },
        {
        Name = "ACCESSORIES ROUSES 342";
        id = 29;
    },
        {
        Name = ACE;
        id = 30;
    },
        {
        Name = "ACHILLES (PAZZION)";
        id = 31;
    }
  )  
    my code:-
    ------------

    - (void)connectionDidFinishLoading:(NSURLConnection *)connection {

        NSString * allDataDictionbary = [[NSString alloc] initWithData:webData encoding:NSUTF8StringEncoding];

      NSDictionary * responseString = [allDataDictionbary JSONValue];

      NSLog(@"final respone dictionary%@",responseString);

     NSMutableArray * mainArray = [[NSMutableArray alloc]init];
         [mainArray addObject:responseString];

         for (int i = 0; i<mainArray.count; i++) {


                NSDictionary *BatchDict = [mainArray objectAtIndex:i];

                NSString * name = [BatchDict objectForKey:@"Name"];
                NSString * Id = [BatchDict objectForKey:@"id"];

                [NameArray addObject:name];
                [IdArray addObject:Id];
            }


            NSLog(@"so finally name array%@",NameArray);
            NSLog(@"so finally Id array%@",IdArray);
    }

您将数组作为字典是错误的。您正在将一个数组添加到数组中，并将这个添加的数组视为字典。

您只需要枚举 JSON 数组对象..
