Why this talk?
started with RestKit 0.10 last year
RestKit in the real world
Examples sucked
zondag, 22 september 2013
Typical Example
simple JSON feed of one type
load objects from feed
zondag, 22 september 2013
Example setup
Create:
Custom Class
RKObjectManager (singleton)
RKObjectMapping
Fetch objects
zondag, 22 september 2013
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
Solution 0.10
use separate
RKObjectLoader
RKObjectMappingProvider
zondag, 22 september 2013
RestKit 0.20
based on AFNetworking framework
cleaner object mapping
more blocks, less delegates
zondag, 22 september 2013
Flow 0.20
based on NSOperation:
RKObjectRequestOperation
RKResponseMapperOperation
RKObjectMappingOperation
zondag, 22 september 2013
Flow setupAFHTTPClient
RKObjectManager (singleton)
RKObjectMapping(s)
(RKRelationshipMapping)
RKResponseDescriptor
[[RKObjectManager sharedManager] getObjectsAtPath]
zondag, 22 september 2013
Two Basic Flowstoplevel based
add response to RKObjectManager
fetch objects
fine-grained
add response to RKObjectRequest
RKObjectRequestOperation

Converting from RestKit 0.10 to 0.20 is a lot of work
