유니티 네비게이션바 보이기, 감추기, 색상 변경하는 방법
Unity 개발중 Navigation Bar를 보이거나, 감추거나 또는 고정하는 방법들에 대해 소개합니다.
네비게이션바 항상 고정
네비게이션바를 항상 노출 시키는 방법은 간단합니다.
Screen.fullScreen = false;fullScreen이 아니다.는 선언만 있으면 되는데요. Awake 또는 Start 함수에 적어두면 항상 네비게이션 바를 고정할 수 있습니다.
네비게이션바 감추는 방법
네비게이션바를 감추는 방법은 노출하는 방법의 반대입니다.
Screen.fullScreen = true;fullScreen을 true 값으로 선언해주면 됩니다.
네비게이션바 색상 변경하는 방법
네비게이션바의 색상을 변경 할 수도 있습니다.

위와 같은 ApplicationChrome 클래스를 하나 만들어 줍니다.
그리고 다른 코드에서 다음 두줄을 선언해 주면 됩니다.
ApplicationChrome.navigationBarState = ApplicationChrome.States.Visible;
ApplicationChrome.navigationBarColor = 0xFF000000;다만 위의 방법으로 네비게이션바를 노출 시키면서 애드몹 배너광고를 bottom 값으로 노출시킬 경우 네비게이션바와 배너광고가 서로 겹치는 경우가 발생할 수 있습니다.
