                    "extras": false
                }
            }
        },
        "1278": {
            "type": "product",
            "product_id": 1222,

                    "catname": "rer",
                    "extras": true
                },
                "2": {
                    "price": 6.2,
                    "pos": 2,
                    "catname": "mega",
                    "extras": true
                }
            }
        },

NSArray *arr = [[NSArray alloc]initWithArray:[dictionary allKeys]]; you'll get the array of all keys. — ChintaN -Maddy- Ramani, Jan 31 '13 at 09:18
then you can compare keys with the response and get the whole dictionary back as per your key. — ChintaN -Maddy- Ramani, Jan 31 '13 at 09:22

Just convert your JSON Data into an object

NSData *jsonData = //response data

NSDictionary *object = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error:nil];

Then there is no parsing involved, you just deal with the dictionary. (Or array, etc...)

To get the list you want you can then do...

NSArray *requiredValues = [object allKeys];

Why would you first convert your `NSData` object to an `NSString` (ASCII? really?) and then back to `NSData` instead of just using `self` in `JSONObjectWithData:`? I don't see why you'd need a category method for something that is a one-liner anyway. – omz Jan 31 '13 at 09:20
I dunno, it's just something I used a while back and it stuck. Good point thoguh. – Fogmeister Jan 31 '13 at 09:31
