Xcode 4.2 with Storyboard - 텍스트 필드가 할당되지 않았습니다.

Xcode 4.2를 Storyboards로 배우고 있으며 범용 앱을 만들려고합니다.Xcode 4.2 with Storyboard - 텍스트 필드가 할당되지 않았습니다.

모두 iPhone에서 잘 작동하지만 iPad 측에서는 분할보기 컨트롤러의 상세보기에 3 개의 텍스트 필드 (1 TextField, 2 TextViews)를 할당하는 데 문제가 있습니다.

스토리 보드에서 새로운 기능을 사용하여 세부 정보 헤더 파일에 대한 세부 정보 필드의 새 필드를 연결하고 자동으로 속성 및 합성 문을 작성합니다 (매우 멋진 기능).

그러나 세부 필드 (값을 메서드 drinkChanged)에 할당하고자하는 지점에 도달하면 DetailViewController보기에 아무 것도 표시되지 않습니다. 나는 사전 값이 할당 시간에 존재 함을 확인했다.

흥미로운 점은 viewWillAppear가 호출 될 때 refreshView 메소드가 호출되면 작동한다는 것입니다. 그러나 refreshView 메소드가 drinkChanged에 의해 호출되면 (사용자가 MasterViewController 테이블에서 행을 선택했음을 의미 함) 작동하지 않습니다.

어디에서 버스를 놓칠 수 있는지 알고 있습니까?

마지막 3 줄 내가 사전 키의 값을 얻을 것으로 기대하고 있습니다 대신 그들이 다시 (NULL)을하는 곳입니다
