dictionary output is

{ "charity_amt" = "0.20"; "charity_id" = 2; "charity_name" = givedirectly; } 

you don't need componentseparatedbystring. once nsdictionary @"category", can value using keys.

something

if ([json iskindofclass:[nsdictionary class]]){     nsarray *yourstaffdictionaryarray = json[@"array"];     if ([yourstaffdictionaryarray iskindofclass:[nsarray class]]){         (nsdictionary *dictionary in yourstaffdictionaryarray) {              nsdictionary *dict = dictionary[@"category"];             nslog(@"%@",dict[@"charity_id"]);         }     } }
