중복 파일이 없음 : 링커 명령이 종료 코드 1과 함께 실패했습니다 (호출을 보려면 -v 사용)

Question

내 프로그램에서 "종료 코드 1로 실패한 링커 명령 (-v를 사용하여 호출)"오류가 발생했습니다. 그리고 무엇을해야할지 모르겠습니다. 네, 다른 질문이 있다는 것을 알고 있습니다. 다른 해결책을 시도했지만 문제가 다르다고 생각합니다. 내 바탕 화면과 라이브러리/개발자의 프로젝트 파일에 모두 체크했는데, 그것이 무엇인지 말해 주더라도 중복 된 클래스를 찾을 수 없습니다.

필요한 경우 내 코드도 제공 할 수 있지만 잘하면 할 필요가 없습니다. 감사합니다. : D

Answer 1

"main.m 수입 Pea.h Pea.h는 Plant.m를 가져옵니다 , ... ".

문제가 있습니다. "Pea.h"는 "Plant.m"이 아니라 "Plant.h"를 가져와야합니다.

은 그렇지 않으면 "Plant.m"의 Plant 클래스는 에 컴파일 중복 정의 오류로 이어지는, "Pea.h", "main.m"예를 들면 을 가져 모든 소스 파일.
