아래 코드는 사용자가 테이블 뷰 셀에서 길게 누르는 제스처를 수행하면 UIActionSheet이 UITextField으로 시작된다는 것을 보여줍니다. UITextField을 탭하면 키보드가 시작되고 textFieldShouldBeginEditing 및 textFieldDidBeginEditing이 호출되지만 텍스트 필드는 키 탭을 허용하지 않습니다.UITextField의 UIActionSheet에서 일부 대리자 메서드 만 호출
반환 키를 누르면 대리자 메서드가 트리거되지 않지만 UIActionSheet 단추 중 하나를 누르면 textFieldShouldEndEditing이 표시되고 textFieldDidEndEditing이 트리거됩니다.
textField가 첫 번째 응답자가되도록 설정 했으므로 키보드 입력을받지 않는 이유가 확실하지 않습니다. 어떤 제안?
