uipopover 컨트롤러가 단선 해제되었습니다.

Question

제가 생각하기에, UHPopoverController가 클래스 변수이므로 이상한 경우 UIPopoverController이 해제되기 전에 문제가 발생합니다. 어떤 도움이라도 대단히 감사 할 것입니다. 여기

에 수업하고 있어요되어 도움

Answer 1

나는 Edit이 여러 번 호출되어 다중 UIPopoverController이 인스턴스화되는 결과입니다. 그럴 경우 다음과 같이 수정하면됩니다.

public void Edit() 
{ 
    if (_popup != null && _popup.PopoverVisible) { 
     _popup.Dismiss (false); 
     _popup.Dispose(); 
    } 

    //your code 
} 

Answer 2

몇 주셔서 대단히 감사합니다 아이디어 :

• Edit은 한 번만 호출됩니다.
• ViewView도 삭제되어 있지 않은지 확인하십시오. Dispose 오버로드를 구현하고 중단 점 또는 Console.WriteLine을 입력하여이를 쉽게 수행 할 수 있습니다.
