iOS 7 용 iPad 설정 응용 프로그램 세부 정보보기 와 같은 스타일의 그룹 UITableView를 갖고 싶습니다 .
모서리가 둥근 tableView입니다. 자세한 내용은 첨부 파일을 확인하십시오.
그렇게 보이게하기위한 몇 가지 기본 설정이거나 같은 것에 대해 사용자 정의 드로잉을해야합니다.
올바른 방향으로 힌트를 주시면 감사하겠습니다.

iOS 13 이상에서이 테이블 스타일은 새로운 UITableView.Style.insetGrouped 테이블 뷰 스타일 로 다시 엔지니어링 할 필요없이 Apple에서 마침내 사용할 수있게되었습니다 .
Xcode 11 이상에서는 스타일에 대해 Inset Grouped를 선택하여 테이블보기의 인터페이스 빌더 설정에서 설정할 수 있습니다.

@jvanmetre의 대답은 훌륭하고 작동합니다. 그 위에 구축하고 댓글에서 @SergiySalyuk이 제안한대로. 대신 UIBezierPath를 사용하도록 코드를 업데이트하여 이해하기 쉽고 약간 더 빠르게 만들었습니다.
내 버전은 또한 구분자 버그를 수정하고 셀에 맞는 선택된 배경보기를 추가합니다.
테이블보기를 구분 기호 없음으로 설정해야합니다. tableView.separatorStyle = UITableViewCellSeparatorStyleNone;

여기에 몇 가지 답변을 시도 후, 나는 전체 돼지를 가서 위에 전체 서브 클래스를 구현하기로 결정 UITableView하고 UITableViewCell아이폰 OS 7의 둥근 그룹화 된 테이블 뷰 스타일을 복제 할 수 있습니다.
https://github.com/TimOliver/TORoundedTableView
결국 매우 복잡한 프로세스가되었습니다.

layoutSubviews를UITableView각 셀과 액세서리 뷰를 중계 해야했기 때문에 더 이상 에지 투 에지가 아니었다. - 나는 서브 클래스를해야했다
UITableViewCell상단 및 하단 구분선보기를 제거하기 위해 를 만들어야했습니다 (단, 섹션 내부의보기는 그대로 둡니다). - 그런 다음
UITableViewCell각 섹션의 첫 번째 및 마지막 셀에 사용할 상단과 하단에 둥근 모서리를 선택적으로 포함 할 수 있는 사용자 지정 배경보기 를 만들었습니다 . 이러한 요소는 사용자가 셀을 탭할 때 배경 뷰의 색상을 변경하는의 암시 적 동작CALayer을 방지해야했습니다UITableView. - 이제는에
CALayer응답하지 않는 인스턴스 이기 때문에layoutSubviews사용자가 장치를 회전 할 때 상단 및 하단 셀의 크기가 다른 셀과 동일한 속도로 조정되도록하기 위해 코어 애니메이션 땜질을해야했습니다.
대체로 할 수는 있지만 상당한 노력이 필요하고 약간의 성능이 필요하기 때문에 (모든 것을 되돌리려는 Apple의 코드와 지속적으로 싸우기 때문에) Apple에 요청하는 것이 가장 좋습니다. 공식적으로 그 스타일을 공개합니다. 그때까지는 내 라이브러리를 자유롭게 사용하십시오. 🙂
