RestKit 0.20.0-pre3 오류 - [NSManagedObjectContext saveToPersistentStore :] : 인스턴스로 전송 된 인식 할 수없는 선택자

Question

CocoaPods를 통해 RestKit (0.20.0-pre3)을 설치하고 설명서에서 설명한대로 구성했습니다. getObjectsAtPath을 수행하고 RestKit이 매핑을 수행 할 때 내가 얻을 :

* 인해 캐치되지 않는 예외 'NSInvalidArgumentException'응용 프로그램 종료, 이유는 : '- [NSManagedObjectContext saveToPersistentStore :] : 인식 할 수없는 선택기 예를 0x9eaae40로 전송'

I는 라인 (278)

다음 I가 RestKit 구성에 RKManagedObjectRequestOperation.m 정차 중단 점을 설정할 경우

이것은 링커 플래그가 제대로 설정되지 않았 음을 나타냅니다. 범주 메서드를로드하려면 -ObjC 링커 플래그가 필요합니다. 타겟에서 Linker Flags를 재정의 했습니까? 대상 수준에서 추가 구성이있는 경우 적어도 $(inherited)을 포함해야합니다. Xcode에서 설정을 볼 때 -ObjC이 링커 플래그 내에 표시되어야합니다.
