    addChild(label);
    
    //自身做顺时针旋转动作
    sender->runAction(CCRepeatForever::create(CCRotateBy::create(1, 360)));

//CCNode* sender也就是CCSprite* callFuncNDSp. void的字面意思是“无类型”，void*则为“无类型指针”，void*可以指向任何类型的数据。

    addChild(label);
    
    //自身做逆时针旋转动作
    sender->runAction(CCRepeatForever::create(CCRotateBy::create(1, -360)));
    
    //void* data也就是CCLabelTTF* title
    CCLabelTTF* title = (CCLabelTTF*)data;
    title->runAction(CCRepeatForever::create(CCJumpBy::create(1, ccp(0, 0), 30, 2)));
