NSTableView의 사용자 지정 NSPopupButtonCell

Question

테이블 뷰에서 사용자 지정 팝업 메뉴를 만들려고합니다. 내가 이해할 수있는 것처럼 [NSPopupButtonCell setView : myView] 메서드를 호출하여 사용자 정의 뷰 (NSView에 NSOutlineView가있는)에 전달하면이 작업을 수행 할 수 있어야합니다.

그래서 나는 NSPopupButtonCell 서브 클래스를 생성하고

편집 .. 초기화하는 동안 나는 setView를 호출하고 사용자 정의 개요보기를 전달 나는 팝업 버튼에 테이블 열 셀을 설정 한 IB에서

셀을 열고 내 맞춤 LookupPopupButtonCell에 클래스를 설정하십시오.

아직 내 사용자 지정보기가 표시되지 않지만 사용자 지정 클래스 초기화 메서드가 호출되는 것으로 보입니다.

이후 NSTableViewDelegate 메소드 dataCellForTableColumn을 사용하여이 접근 방식을 대체했습니다. 이제 팝업이 내 사용자 정의 tableView를 보여줍니다.

그래도 NSOutlineViewDelegate 메소드를 가져 오는 데 큰 기쁨이 없습니다.

EDIT 확인보기에서 NSPopupButton을 사용하여 작업 할 수있었습니다. 위임자 찾기 및 테이블보기는 문제가없는 항목을 표시합니다. NSPopupButtonCell을 사용하면 대리자 메서드가 호출되지 않는다고합니다.

대리자 메시지를 가져 오기 위해서는 VIEW 기반 tableView를 사용해야합니다. Blah, 이제 Core Data에 바인딩하는 방법을 알아 냈습니다.

각 행에 대해 동일한 메뉴를 재사용 할 수있는 방법이 있습니까? 아마 dataSource가 너무 나쁘지는 않을 때마다 다시 만들어지지 않는 한이 계층 구조에 많은 행이있을 수 있습니다.
