clang으로 컴파일러 오류가 발생했습니다 : 오류 : 종료 코드 1을 사용하여 링커 명령이 실패했습니다 (호출을 보려면 -v 사용)

Question

앱을 만들었고 성공적으로 완료했습니다. 단지 Fcebook에서 공유하려고하고 자습서를 참조하여 시도했습니다. . 여기 viewcontroller.m 파일에 내 코드가있다.

편집 :

귀하의 코멘트에서

, 당신은 또한 당신의 프로젝트에 페이스 북 SDK 샘플과 함께 제공되는 main.c 파일을 복사 (또는 당신 삭제 될 수 있습니다; main.c를 만 상용구 코드를 포함하는) 것 같다. 그것을 제거 (또는 더 나은, 샘플과 관련된 모든 파일을 제거), 그리고 그것은 작동합니다.

내 생각에 앱을 페이스 북 프레임 워크와 올바르게 연결하지 않았지만 컴파일러에서 얻은 정확한 오류 메시지를 실제로 살펴 봐야한다.

첫 번째 사항은 Create your iOS project입니다.

두 번째로, Xcode 4에서 첨부 된 그림과 같은 "경고"아이콘을 클릭하십시오. 당신이 더 많은 도움이 필요하면

, 당신은 링커에서 얻을 정확한 오류를보고하십시오.
