Core Data와 RestKit이 새로 도입되었으므로 이미 Core Data와 RestKit에 대한 자습서를 많이 읽었지만 서버에서 데이터를 가져올 수 없습니다. 내 애플 리케이션에서 데이터를 얻고, DB에 저장하고, DB가 있거나 인터넷에 연결되어 있지 않으면 RestKit이 나를 위해 그것을 할 수 있다는 것을 알고 있지만, 내 데이터를 얻으 려 할 때 http://salatiki.com.ua/api/get.php?getSaladsType에서 볼 수있다. 몇 가지 오류와 아무 일도 일어나지 않습니다. 제발 저를 도와주세요. 내가 뭘 잘못하고있는 걸까요? 나는 유용한 참고 문헌에 대해 매우 감사 할 것입니다. 고맙습니다.RestKit 0.20은 서버에서 데이터를 가져올 수 없습니다.
