RestKit：連接ID與實體

Question

的陣列我有JSON響應：

{ ids: [1,2] } 

而CoreData實體

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

如何IDS從實體陣列連接？

Answer 1

添加創建映射

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