시스템 메서드 호출 순서 인쇄 노트 ------

A 컨트롤러 push에서 B 컨트롤러로 pop하는 과정
4+(void) initialize 및 4+(void)load이 두 가지 방법은 파일에 따라 불러오는 것이다. 가장 최근에 호출된 방법이다. 모든 파일이 있고 한 번만 호출된다. 그 다음에 컨트롤러의 생명주기가 있다. 이것은 실제 장면(코드를 쓰지 않아도 상상에 의존)을 결합시켜야 더욱 잘 이해할 수 있다.

하나의 대상을 실례화하고Category를 이용하여 하나의 대상의setter와 Getter를 연결하여 하나의 방법을 호출한 다음에 호출 순서가 이렇다. 먼저 set을 호출한 다음에 인쇄 방법을 호출하고 인쇄 방법에서 get을 호출한다.
