按钮可以点击时与不可以点击控制
string[] btnSpriteName = { "cm_btn_grey", "cm_btn_16" };
        Color[] btnValueColor = { new Color(106 / 255.0f, 106 / 255.0f, 106 / 255.0f), new Color(31 / 255.0f, 134 / 255.0f, 0) };
        UILabel uiLabel = mBtn.transform.FindChild("Value").GetComponent();
        UISprite uiSprite = mBtn.GetComponent();
        UIButton uiButton = mBtn.GetComponent();
        BoxCollider boxCollider = mBtn.GetComponent();
        if (isReceived)
        {
            if (!uiButton.isEnabled)
                uiButton.enabled = true;
            if (!boxCollider.enabled)
                boxCollider.enabled = true;
        }
        else
        {
            if (uiButton.isEnabled)
                uiButton.enabled = false;
            if (boxCollider.enabled)
                boxCollider.enabled = false;
        }

        uiSprite.spriteName = btnSpriteName[System.Convert.ToInt32(isReceived)];
        uiLabel.effectColor = btnValueColor[System.Convert.ToInt32(isReceived)];

需要先控制BoxCollider和UIButton，再修改图片，顺序不可乱，否则图片切换不过来
