cocos2dx -- CREATE_FUNC

创建对象，然后自动释放内存，可以不用管理内存！


/** 
 * define a create function for a specific type, such as CCLayer 
 * @__TYPE__ class type to add create(), such as CCLayer 
 */  
#define CREATE_FUNC(__TYPE__) \  
static __TYPE__* create() \  
{ \  
    __TYPE__ *pRet = new __TYPE__(); \  
    if (pRet && pRet->init()) \  
    { \  
        pRet->autorelease(); \  
        return pRet; \  
    } \  
    else \  
    { \  
        delete pRet; \  
        pRet = NULL; \  
        return NULL; \  
    } \  
}
