今天学习cocos2dx的时候发现原来所有选择器要求传递的回调函数的参数是有限制的，看了库中的定义后就遇到的整理如下，仅供参考，Cocos2dx版本2.2.3：

?

选择器参数说明

schedule_selector（浮点数）[float dt]

?

callfunc_selector（无参数）[void]

?

callfuncn_selector（节点）[CCNode *node]

?

callfuncND_selector(节点，任意参数)[CCNode *node,void *any]

?

callfuncO_selector(对象)[CCObject *pSender]

?

menu_selector(对象)[CCObject *pSender]

?

event_selector(事件)[CCEvent *event]

?

compare_selector(对象)[CCObject *pSender]

?

?

原始的声明如下

typedef void (CCObject::*SEL_SCHEDULE)(float);

typedef void (CCObject::*SEL_CallFunc)();

typedef void (CCObject::*SEL_CallFuncN)(CCNode*);

typedef void (CCObject::*SEL_CallFuncND)(CCNode*, void*);

typedef void (CCObject::*SEL_CallFuncO)(CCObject*);

typedef void (CCObject::*SEL_MenuHandler)(CCObject*);

typedef void (CCObject::*SEL_EventHandler)(CCEvent*);

typedef int (CCObject::*SEL_Compare)(CCObject*);

?

对应选择器宏

#define schedule_selector(_SELECTOR) (SEL_SCHEDULE)(&_SELECTOR)

#define callfunc_selector(_SELECTOR) (SEL_CallFunc)(&_SELECTOR)

#define callfuncN_selector(_SELECTOR) (SEL_CallFuncN)(&_SELECTOR)

#define callfuncND_selector(_SELECTOR) (SEL_CallFuncND)(&_SELECTOR)

#define callfuncO_selector(_SELECTOR) (SEL_CallFuncO)(&_SELECTOR)

#define menu_selector(_SELECTOR) (SEL_MenuHandler)(&_SELECTOR)

#define event_selector(_SELECTOR) (SEL_EventHandler)(&_SELECTOR)

#define compare_selector(_SELECTOR) (SEL_Compare)(&_SELECTOR)

?

?

?

cccontrol_selector（对象，整数）[CCObject *pSender,CCControlEvent]

?

原始声明如下：

typedef unsigned int CCControlEvent;

?

typedef void (CCObject::*SEL_CCControlHandler)(CCObject*, CCControlEvent);

?

对应选择器宏：

#define cccontrol_selector(_SELECTOR) (SEL_CCControlHandler)(&_SELECTOR)
