6. WHY? communicating with backend but JSON is easy! zondag, 22 september 2013
7. WHY? communicating with backend but JSON is easy! [NSJSONSerialization  JSONObjectWithData:responseData] zondag, 22 september 2013
8. WHY? communicating with backend but JSON is easy! error checking zondag, 22 september 2013
9. WHY? communicating with backend but JSON is easy! error checking easy mapping to CoreData zondag, 22 september 2013
10. WHY? communicating with backend but JSON is easy! error checking easy mapping to CoreData zondag, 22 september 2013
11. WHY? communicating with backend but JSON is easy! error checking easy mapping to CoreData xml & json agnostic zondag, 22 september 2013
12. Why this talk? started with RestKit 0.10 last year RestKit in the real world Examples sucked zondag, 22 september 2013
13. Typical Example simple JSON feed of one type load objects from feed zondag, 22 september 2013
14. Example setup Create: Custom Class RKObjectManager (singleton) RKObjectMapping Fetch objects zondag, 22 september 2013
15. Real-World multiple different json feeds post multiple compound json objects different responses (data, error) restkit 0.10 objectmanager couldn’t cope zondag, 22 september 2013
16. Solution 0.10 use separate RKObjectLoader RKObjectMappingProvider zondag, 22 september 2013
17. RestKit 0.20 based on AFNetworking framework cleaner object mapping more blocks, less delegates zondag, 22 september 2013
18. Flow 0.20 based on NSOperation: RKObjectRequestOperation RKResponseMapperOperation RKObjectMappingOperation zondag, 22 september 2013
19. Flow setup AFHTTPClient RKObjectManager (singleton) RKObjectMapping(s) (RKRelationshipMapping) RKResponseDescriptor [[RKObjectManager sharedManager] getObjectsAtPath] zondag, 22 september 2013
20. Two Basic Flows toplevel based add response to RKObjectManager fetch objects fine-grained add response to RKObjectRequest RKObjectRequestOperation zondag, 22 september 2013
