ios - JSON Object Mapping - RestKit -

i have below json response. how can object mapping it? using ios - restkit.

    {      "predictions":[         {            "description":"user1",          "id":"75b8c57b4443f4b881f0efc94afd52437232aee9"       },       {            "description":"user2",          "id":"82aa3303704041cda0e4fc34024d383dbf923604"       },       {            "description":"user3",          "id":"f88f669a30934ef599bccf86c0236426cf2d313e"       },       {            "description":"user4",          "id":"fa9ae7b65fa52bffdabf00d69e7db5cd37539781"       },       {            "description":"user5",          "id":“66df3fd7e400eb31efd3ac935036aab2c02b03f0"       }    ],    "status":"ok" } 

create new class called prediction description , predictionid properties , use mapper object

rkobjectmapping *mapping = [rkobjectmapping mappingforclass:[prediction class]]; [mapping addattributemappingsfromdictionary:@{ @"description":   @"description", @"id":     @"predictionid", }]; 

of course after parse response correctly
