    CCScene * scene = B::scene();
    B * layer = (B*)(scene->getChildren()->objectAtIndex(0));
    layer->value = "要传的值";
    CCDirector::sharedDirector()->replaceScene(scene );
}

B.h

class B: public cocos2d::CCLayer
{

    virtual void onEnter();
    static CCScene * scene();

    CCString value;
