1，没黑边没拉伸

    float scaleX = size.width / 640;    float scaleY = size.height / 960;    float scale = scaleX < scaleY ? scaleX : scaleY;        //背景    auto uilayerUp = GUIReader::getInstance()->widgetFromJsonFile("menu/newGameMenu/jiemianhsang.json");    uilayerUp->setScale(scale);    uilayerUp->setTouchEnabled(false);    uilayerUp->setAnchorPoint(Vec2(0.5, 1));    uilayerUp->setPosition(Vec2(size.width / 2, size.height));    this->addChild(uilayerUp, -1);        auto uilayerDown = GUIReader::getInstance()->widgetFromJsonFile("menu/newGameMenu/jiemianxia.json");    uilayerDown->setScale(scale);    uilayerDown->setTouchEnabled(false);    uilayerDown->setAnchorPoint(Vec2(0.5, 0));    uilayerDown->setPosition(Vec2(size.width / 2, 0));    this->addChild(uilayerDown, -1);        auto uilayerCenter = GUIReader::getInstance()->widgetFromJsonFile("menu/newGameMenu/jiemianzhong.json");    uilayerCenter->setScale(scale);    uilayerCenter->setTouchEnabled(false);    uilayerCenter->setAnchorPoint(Vec2(0.5, 0.5));    uilayerCenter->setPosition(Vec2(size.width / 2, size.height / 2));    this->addChild(uilayerCenter, 0);

2，选关界面

把宽度和高度进行拉伸，进行填充.

锚点虽然在（0，0）点，锚点的位置时拉伸后，占据的百分比。
