NGUI自适应屏幕

主要是改变Manual Height

制作UI时按640*960标准

一般在Awake()中调用

static private void AdaptiveUI()
{
int ManualWidth = 960;
int ManualHeight = 640;
UIRoot uiRoot = GameObject.FindObjectOfType<UIRoot>();
if (uiRoot != null)
{
if (System.Convert.ToSingle(Screen.height) / Screen.width > System.Convert.ToSingle(ManualHeight) / ManualWidth)
uiRoot.manualHeight = Mathf.RoundToInt(System.Convert.ToSingle(ManualWidth) / Screen.width * Screen.height);
else
uiRoot.manualHeight = ManualHeight;
}
}
