加载CCBI

加载ccbi，返回CCNode

      CCNode* LoadCCBIFile(
       const char* ccbiFileName,
       CCObject *pOwner,
       const char* ccbiRootPath= NULL
       )
      {

         CCBReader* pReader = new CCBReader(CCNodeLoaderLibrary::sharedCCNodeLoaderLibrary());
         pReader->autorelease();
         //设置ccbi的目录
         if (ccbiRootPath)
         {
           pReader->setCCBRootPath(ccbiRootPath);
         }

         //加载ccbi

         CCNode* pNode = pReader->readNodeGraphFromFile(ccbiFileName,pOwner);
         return pNode;
      }

连接自己定义类

 一、在CocosBuilder中绑定类和成员

  1.创建一个CCLayer

        

  2.在Document->JavaScript Controller勾去掉，就可以设置C++自定义类。

  3.在右边Code connetctions中，Custom Class输入定义的类名。

  4.选择Doc Root Var指定为成员变量

  5.为CCMenu或CCControlButton指定回调函数。在selector中输入回调函数，Target指定为

    Document root。

        

 二、代码连接

   1.为ccbi指定一个CCLayerLoader，CCLayerLoader只需要指定一个静态方法创建CCLayerLoader对 

 象，还需要一个静态方法创建ccbi连接的类

       class MyLayerLoader
        : public CCLayerLoader
       {
       public:
        CCB_STATIC_NEW_AUTORELEASE_OBJECT_METHOD(MyLayerLoader);
        CCB_STATIC_NEW_AUTORELEASE_OBJECT_WITH_INIT_METHOD(HelloWorld);
       };

       #define CCB_STATIC_NEW_AUTORELEASE_OBJECT_METHOD(T, METHOD) static T * METHOD() { \
        T * ptr = new T(); \
        if(ptr != NULL) { \
        ptr->autorelease(); \
        return ptr; \
        } \
        CC_SAFE_DELETE(ptr); \
        return NULL; \
       }

       #define CCB_STATIC_NEW_AUTORELEASE_OBJECT_WITH_INIT_METHOD(T, METHOD)\

        static T * METHOD() { \
        T * ptr = new T(); \
        if(ptr != NULL && ptr->init()) { \
        ptr->autorelease(); \
        return ptr; \
        } \
        CC_SAFE_DELETE(ptr); \
        return NULL; \
       }

  2.设计ccbi连接的类，首先必须继承于CCLayer和CCBMemberVariableAssigner，如果cocosBuilder

 使用了selector，还需要继承CCBSelectorResolver类。

     class HelloWorld
      : public CCLayer,
        public CCBMemberVariableAssigner,
        public CCBSelectorResolver
     {
     public:
      CCB_DECL(HelloWorld); //在最后定义
      HelloWorld();
      ~HelloWorld();

      //CCBMemberVariableAssigner中的虚函数
      virtual bool onAssignCCBMemberVariable(CCObject* pTarget,

          const char* pMemberVariableName, CCNode* pNode);

      virtual bool onAssignCCBCustomProperty(CCObject* pTarget,

          const char* pMemberVariableName, CCBValue* pCCBValue); 

      //CCBSelectorResolver中需要实现的函数
      virtual SEL_MenuHandler onResolveCCBCCMenuItemSelector(CCObject * pTarget,

          const char* pSelectorName){return NULL;}
      virtual SEL_CCControlHandler onResolveCCBCCControlSelector(CCObject * pTarget,

          const char* pSelectorName);
     private:
      CCControlButton* m_pTestBtn;
     };

   3.实现CCBMemberVariableAssigner::onAssignCCBMemberVariable为成员赋值，

     实现CCBSelectorResolver::onResolveCCBCCMenuItemSelector和

     CCBSelectorResolver::onResolveCCBCCControlSelector为CCmenuItem和CCControlButton指

   定回调函数。
     bool KLRoleCardLayer::onAssignCCBMemberVariable( CCObject* pTarget,

         const char* pMemberVariableName, CCNode* pNode )
     {
        //第二个参数是cocosBuider中自定的名字
        CCB_MEMBERVARIABLEASSIGNER_GLUE(this,  KL_TOSTRING(m_pTestBtn),

              CCControlButton* ,m_pTestBtn);

        return false;
     }

     cocos2d::extension::SEL_CCControlHandler HelloWorld::onResolveCCBCCControlSelector(

                    CCObject * pTarget, const char* pSelectorName )
     {
        CCB_SELECTORRESOLVER_CCCONTROL_GLUE(this, "OnPressButton", HelloWorld::OnClickBtn);
        return NULL;
     }

 

     //在cocosBuilder添加int，float，string，bool类型的成员通过这个函数赋值

      bool HelloWorld::onAssignCCBCustomProperty(CCObject* pTarget,

           const char* pMemberVariableName, cocos2d::extension::CCBValue* pCCBValue)
     {
      bool bRet = false;
      if (pTarget == this)
      {
       if (0 == strcmp(pMemberVariableName, "mCustomPropertyInt"))
       {
        this->mCustomPropertyInt = pCCBValue->getIntValue();
        bRet = true;
       }
       else if ( 0 == strcmp(pMemberVariableName, "mCustomPropertyFloat"))
       {
        this->mCustomPropertyFloat = pCCBValue->getFloatValue();
        bRet = true;
       }
       else if ( 0  == strcmp(pMemberVariableName, "mCustomPropertyBoolean"))
       {
        this->mCustomPropertyBoolean = pCCBValue->getBoolValue();
        bRet = true;
       }
       else if ( 0  == strcmp(pMemberVariableName, "mCustomPropertyString"))
       {
        this->mCustomPropertyString = pCCBValue->getStringValue();
        bRet = true;
       }

      }

      return bRet;
     }

   注意：构造函数中必须将需要赋值的变量赋值为pTestBtn = NULL，否则 onAssignCCBMemberVariable将赋值失败。同时，在析构函数中CC_SAFE_RELEASE_NULL(m_pTestBtn);来释放资源。
