1. 獲取一個(gè)UI的大小

    public static Vector2 GetSize(RectTransform rect, Space space = Space.Self)

    {

        var size = rect.rect.size;

        if(space == Space.World)

        {

            var canvasList = rect.GetComponentsInParent<Canvas>();

            var canvas = canvasList[canvasList.Length - 1];

            return MathTools.Division(MathTools.Multiple(size, rect.lossyScale), canvas.transform.lossyScale);

        }

        return size;

    }

2. 設(shè)置一個(gè)UI的大小

    public static void SetSize(RectTransform rect, Vector2 targetSize, Space space = Space.Self)

    {

        if(space == Space.World)

        {

            var canvasList = rect.GetComponentsInParent<Canvas>();

            var canvas = canvasList[canvasList.Length - 1];

            targetSize = MathTools.Multiple(MathTools.Division(targetSize, rect.lossyScale), (canvas.transform).lossyScale);

        }

        var originSize = rect.rect.size - rect.sizeDelta;

        var makeSizeDelta = targetSize - originSize;

        rect.sizeDelta = makeSizeDelta;

    }
