KSMapper Module will convert (parse) your server JSON values directly in to your Model (NSObject) classes same as “ObjectMapper” in swift & “Gson” in Android.
STEP 1 :- Drag KSMapper module in your XCode Project
STEP 2 :- import Mapper.h in your UIViewController where you will fetch web service response
STEP 3 :- Made “NSObject” Model class for each “Dictionary Object” which is coming from server end.
STEP 4 :- Name of “Property” in your “NSObject” class should be same as “key” which is coming from Server end in any Dictionary object (which is the rule of mapping).
That's it Use your filled models entire in the application without any crash .
