一个helloworld场景和setting场景，helloworld.cpp代码如下
#include “HelloWorldScene.h”
#include “SimpleAudioEngine.h”
USING_NS_CC;
Scene* HelloWorld::createScene()
{
return HelloWorld::create();
}
// on “init” you need to initialize your instance
bool HelloWorld::init()
{
//////////////////////////////
// 1. super init first
if ( !Scene::init() )
{
return false;
}
auto visibleSize = Director::getInstance()->getVisibleSize();
Vec2 origin = Director::getInstance()->getVisibleOrigin();
Sprite*bg = Sprite::create("menu/background.png");
bg->setPosition(Vec2(origin.x + visibleSize.width / 2,
origin.y + visibleSize.height / 2));
this->addChild(bg);
//setting
MenuItemImage*settingMenuItem = MenuItemImage::create(
"menu/settingn.png",
"menu/settings.png",
CC_CALLBACK_1(HelloWorld::menuItemSettingCallback, this));
settingMenuItem->setPosition(Director::getInstance()->convertToGL(Vec2(origin.x +
settingMenuItem->getContentSize().width / 2,
origin.y + settingMenuItem->getContentSize().height / 2)));
Menu*mu = Menu::create( settingMenuItem, NULL);
mu->setPosition(Vec2::ZERO);
this->addChild(mu);
return true;
}
void HelloWorld::menuItemSettingCallback(Ref *pSpender)
{
auto sc = Setting::createScene();
Director::getInstance()->pushScene(sc);
}
void HelloWorld::onEnter()
{
Scene::onEnter();
log(“HellowWorld onEnter”);
}
void HelloWorld::onExit()
{
Scene::onExit();
log(“HellowWorld onExit”);
}
void HelloWorld::cleanup()
{
Scene::cleanup();
log(“HellowWorld cleanup”);
}

为什么返回backMenuItem会用不了啊，就是点它返回不了helloworld场景，求大神们指点！！！
