制作如图所示的电子时钟，显示当前的时间。

代码如下

//在初始化函数里创建一个Label，用于显示时间 

m_ttpClock = CCLabelTTF::create("","Arial",18);
 m_ttpClock->setPosition(DZConfig::sharedConfig()->getPoint("config_game","timepiece","pos"));
 m_ttpClock->setColor(ccc3(0xe2,0xe0,0xdc));
 m_ttpClock->setAnchorPoint(ccp(0.5,0.5));
 addChild(m_ttpClock,kZOrderClock);
 m_ttpClock->setVisible(true);
 schedule(schedule_selector(TableView::onTimerClock)); //时时刷新

void TableView::onTimerClock(float dt)

{

//获取当前时间
 struct tm *tm; 
 time_t timevp ;//= now.tv_sec;
 time(&timevp);
 tm = localtime(&timevp);
 int hour = tm->tm_hour;
 int minutes = tm->tm_min;
 int second = tm->tm_sec;
 
 CCString *strTime = CCString::createWithFormat("%02d:%02d",hour,minutes,second);
 m_ttpClock->setString(strTime->getCString());

}
