ugui记录

ugui用到了RectTransform，对ugui的操作 很多体现在RectTransform上：

RectTransform rectT = go.GetComponent<RectTransform>();
            if (texture.width > texture.height)
            {
                rectT.SetSizeWithCurrentAnchors(RectTransform.Axis.Horizontal, originalWidth);
                rectT.SetSizeWithCurrentAnchors(RectTransform.Axis.Vertical, texture.height * originalWidth / texture.width);
            }

RectTransform rectT = go.GetComponent<RectTransform>();
                rectT.offsetMax = new Vector2(-170, tmpY);

RectTransform rectT = txt0.GetComponent<RectTransform>();
        Vector3 vec = rectT.localPosition;
        rectT.localPosition = new Vector3(vec.x, -70, vec.z);
