关于cocos2dx的回调使用

GameTools::buttonPressedAction(widget,CCCallFunc::create(this,callfunc_selector(GameMainMenu::toStageMap)));

void GameTools::buttonPressedAction(UIWidget* widget,CCCallFunc* callFunc)
{
widget->stopAllActions();
CCSequence* seq = CCSequence::create(

CCScaleTo::create(0.1f, 0.9f),
CCScaleTo::create(0.1f, 1.0f),
callFunc,
NULL);    
widget->runAction(seq);
}

参数callFunc传的是GameMainMenu::toStageMap函数的指针，可直接通过该参数对函数进行操作
