보기 컨트롤러 내에 UITableView 설정이있어 함수에서 반환되는 JSON 데이터로 채 웁니다. 나는 MatchCenterViewController, 응용 프로그램 충돌을로드하고 나는 다음과 같은 오류가 나타나면 단순히 말해, 나는이 오류 코드가 참조 UIView tableView:numberOfRowsInSection 확인했습니다numberOfRowsInSection이 인식 할 수없는 선택기 충돌을 일으키고 있습니다.

아하이 봐요. 나는 이것을 어떻게 바꿀 수 있는지 약간 혼란 스럽다. 이것은 스토리 보드 나 구현 파일에서 변경 될 수 있습니까? 스토리 보드 설정에서 테이블 뷰의 클래스를 'MatchCenterViewController'로 변경하려고 시도했지만 'UITableView'로 되돌릴 수 있습니다. – Ghobs
