인사드립니다.의 기본 동작은 UITableView
다음 섹션이 previos 섹션 행을보기 밖으로 밀어 낼 때까지 섹션을 스크롤 할 때 섹션 머리글 행을 테이블 상단에 고정하는 것입니다.
나는 UITableView
내부가 UIViewController
있고 이것은 사실이 아닌 것 같습니다.
그게 기본적인 행동 UITableViewController
입니까?
내가 가진 것을 기반으로 한 간단한 코드가 있습니다. UIController
테이블 뷰를 생성하기 위해 구현 한 인터페이스와 각 테이블 뷰 방법을 보여 드리겠습니다 . 테이블과 함께 사용할 개체를 인덱싱하는 데 도움이되는 도우미 데이터 소스 클래스가 있습니다.
