그럼 난 addExerciseObject 중 하나를 볼 수 없습니다, 그것은 [theSelectedRoutine addRoutineExercisesObject:exercise]; 안?

나는 그 역시 시도했지만, 나는 여전히 같은 오류가 발생합니다. 메소드 -addRoutineExercisesObject를 찾을 수 없다는 메시지가 표시됩니다 (반환 유형의 기본값은 'id'). –

은'.h' 파일에서이 메소드의 프로토 타입입니까? – MByD

아니요. 오류가 지금 바로 끝났습니다. 나는 그들이 .h 자동으로 메소드를 생성했을 것이라고 생각했을 것이다. –
