iOS의 초보자인데, 테이블 뷰를 사용하여 애플리케이션을 생성하고 있습니다. 응용 프로그램을 실행하는 동안 응용 프로그램을 실행하면 응용 프로그램이 cellForRowIndexPath 메서드를 호출하지 않습니다. Json을 웹 서비스로 사용하고 있습니까? 출력 화면에서 파싱 데이터가 표시되지만 시뮬레이터에는 표시되지 않습니다. 나는 중단 점을 넣었고 cellForRowIndexPath 경로가 호출되지 않았 음을 이해했습니다. 나는 datasourse와 data delegate를 xib 파일의 onner 파일로 드래그한다. 하지만 아무것도 테이블 뷰가 표시 얻을입니다 ... 발생하지 않고 아무 내용이없는 ... 나사입니다 .. 모든 사람은 (.H) 인터페이스에서 UITableViewDataSource, UITableViewDelegate 추가 ...cellForRowAtIndexPath 메소드가 호출되지 않았습니다.
