首先，ccb文件是如何生成的，我就不多说了，大家可以搜下cocosbuilder，就能找的相关的教程，而通过cocosbuilder，我们可以省去了很多设计的麻烦，比如设计一个精灵的位置啥的，而通过cocosbuilder，我们可以把我们编码的重点放到具体的控制类上面，而不是在显示页面上下很大的功夫。闲话不多说，要想实现这些好处，首先确定你的Cocos2d-x的版本号，如果是2.0.4，那就用cocosbuilder 2.1吧（当然，cocosbuilder只有mac版的，如果是windows，那就用cocostudio吧），如果cocos2d-x是2.1以上版本，就用cocosbuilder3.0以上版本吧，比如我用的是cocos2d-x2.1.4，我的cocosbuilder为3.0.4。
首先，来看下绑定代码吧 （GameScene.h）

GameScene.cpp文件：

另一个绑定AboutGameSceneLoader.h代码
#ifndef loading_AboutGameSceneLoader_h
#define loading_AboutGameSceneLoader_h
#include "AboutGameScene.h"
class AboutGameSceneLoader:public cocos2d::extension::CCLayerLoader{

mainsprite->runAction(CCRepeatForever::create(CCAnimate::create(animation)));
mainsprite->setPosition(ccp(size.width/4, size.height/3));
}
SEL_MenuHandler AboutGameScene::onResolveCCBCCMenuItemSelector(CCObject * pTarget, const char* pSelectorName)
{

return NULL;

CCDirector::sharedDirector()->replaceScene(tmpaction);
}
void AboutGameScene::setAnimationManager(cocos2d::extension::CCBAnimationManager *value){
}
这些代码和以上的功能相同，贴出来只是让你进一步了解。
最后的实现效果：
