"인식 할 수없는 선택기를 인스턴스로 보내기"UIView의 경우

Question

내 UIView 클래스의 구현을 내 View Controller로 캐스팅하려고했습니다. 그러나, 내 클래스에 대한 메서드를 호출하려고하면 "인식 할 수없는 셀렉터가 인스턴스로 전송되었습니다"가 throw됩니다. 여기

가 내 헤더 파일에서 무엇을하고 무엇을 : 나는 무엇입니까 위와 같이

, 여기에 내가하는 .m 파일을 사용하고있는 무슨이다 다음 코드 줄에서 오류가 발생했습니다.

나는 둘러 보았고, 내 개체에 t가 존재하지 않지만 개체 구현을 왜 보지 못하고 있는지 잘 모르겠습니다. 나는 심지어 UIView에 대한 Identity Inspector의 "GameView"클래스를 사용자 정의 클래스로 설정했습니다.

Answer 1

문제는 펜촉에 있습니다. 보기의 사용자 지정 클래스를 GameView으로 설정하지 않았거나 해당 소유자에게 파일 소유자의 view 콘센트를 연결하지 않았습니다.
