json code read into objective-c

I have this json code: { "search": { "currentlanguage": "en-UK", "searchfields": { "transports": [ { "transportId": "1", "transportName": "flight only" }, { "transportId": "2", "transportName": "package" } ], "departures": [ { "departureId": "1", "departureName": "London" }, { "departureId": "2", "departureName": "Newcastle" } ], "countries": [ { "countryId": "1", "countryName": "Italy" }, { "countryId": "2", "countryName": "Spain" } ], "destinations": [ { "countryId": "2", "destinationId": "1", "destinationName": "Ibiza" }, { "countryId": "2", "destinationId": "2", "destinationName": "Madrid" } ], "flexdays": [ { "flexdayId": "1", "flexdayName": "+2 weeks" }, { "flexdayId": "2", "flexdayName": "+4 weeks" } ], "durations": [ { "durationId": "1", "durationName": "1 week" }, { "durationId": "2", "durationName": "2 weeks" } ] } } } I need the json to be read into objective-c and stored in immutable arrays - like this: array1 = list of transports (where transports is a class or struct) array2 = list of departures array3 = list of countries array4 = list of destinations array5 = list of flexdays array6 = list of durations
