文本菜单示例：

#include "HelloWorldScene.h"

USING_NS_CC;

Scene* HelloWorld::createScene()
{
    auto scene = Scene::create();
    auto layer = HelloWorld::create();
    scene->addChild(layer);
    return scene;
}

bool HelloWorld::init()
{
    if ( !Layer::init() )
    {
        return false;
    }

    Size visibleSize = Director::getInstance()->getVisibleSize();
    Vec2 origin = Director::getInstance()->getVisibleOrigin();

    Sprite *bg = Sprite::create("bg.jpg");
    bg->setPosition(Vec2(origin.x + visibleSize.width/2, origin.y + visibleSize.height/2));
    this->addChild(bg);

    MenuItemFont::setFontName("Times New Roman");
    MenuItemFont::setFontSize(80);
    MenuItemFont *item1 = MenuItemFont::create("Start", CC_CALLBACK_1(HelloWorld::menuItem1Callback, this));　　MenuItemAtlasFont *item2 = MenuItemAtlasFont::create("Help", "fonts/tuffy_bold_italic-charmap.png",48, 65 ,‘ ‘, CC_CALLBACK_1(HelloWorld::menuItem2Callback, this));

    Menu *mn = Menu::create(item1, item2, NULL);
    mn->alignItemsVertically();
    this->addChild(mn);

    return true;
}

void HelloWorld::menuItem1Callback(cocos2d::Ref *pSender)
{
    MenuItem *item = (MenuItem*)pSender;
    log("Touch Start Menu Item %p", item);
}

void HelloWorld::menuItem2Callback(cocos2d::Ref *pSender)
{
    MenuItem *item = (MenuItem*)pSender;
    log("Touch Help Menu Item %p", item);
}
