cocos2d-x 게임 중 일시정지하고 팝업창 띄우기(pause, resume)

●게임 중 화면을 정지 버튼을 누르면 일시정지하고 팝업창을 띄운다. 팝업창에서 버튼은 누르면 다시 게임 화면으로 돌아간다. 팝업창을 띄우고 게임상의 액션,스케줄을 멈추고 재시작하기 위해 " CCDirector::sharedDirector()->pause(); " 을 사용하고 정지버튼터치를 비활성하기 위해 " CCDirector::sharedDirector()->getTouchDispatcher()->addTargetedDelegate(pMenu, kCCMenuHandlerPriority,true); "를 사용한다. 팝업창이 열렸을때, 닫혔을때 구분해서 함수를 실행하기 위해 노티피케이션(Notification)을 이용한다. 노티피케이션은 클래스사이에서 메시지를 주고 받고 하는 싱클톤 객체이다.
