※ IOS에서는 작동하지 않는다 (Ios not working)
IOS에서는 홈 화면으로 돌아갔을 때 필요한 처리를 해주면 된다.
(In iOS, you can do the necessary processing when you return to the home screen.)

홈 화면으로 나갔는지 확인하기 위한 이벤트함수
(Event function to check whether you have gone to the home screen)

func _notification(what):
  if what == MainLoop.NOTIFICATION_WM_FOCUS_IN:
    print("NOTIFICATION_WM_FOCUS_IN")
  elif what == MainLoop.NOTIFICATION_WM_FOCUS_OUT:
    print("NOTIFICATION_WM_FOCUS_OUT")

※ 주의할 점 (caution)
Admob을 사용할 때 전면광고에 진입하여도 _notification 함수가 호출되니 주의가 필요하다. 
(When using admob, you need to be careful because the _notification function is called even if you enter a full-page advertisement.)

[ in Unity ]
Application.Quit();
