RestKit: Connect array of id's with entity

Question

I have JSON response:

{ ids: [1,2] }

And CoreData entity

@property (nonatomic, retain) NSArray *ids;
@property (nonatomic, retain) NSSet<SomeEntity *> *entities;

How to connect ids from array with entities?

Answer 1

Add when creating mapping

[mapping addConnectionForRelationship:@"entities" 
                 connectedBy:@{@"ids":@"someEntityId"}];
