/** Resumes theCocos2d-x和时间有关的代码

Android淘气小公主|2013-09-17 17:28|4007次浏览|代码(34)时间(2)CCDirector(1)0

用cocos2d-x获取系统时间，格式为年月日时分秒：

实现游戏倒计时的代码：

在CCDirector中有个getScheduler()得到时刻表【调度者】，我们可以使用时刻表【调度者】CCScheduler，来暂停所有的调度。在CCScheduler暂停所有的调度是这样子的：

CCScheduler.h

CCSchedule.cpp

暂停之后，我们再次执行的时候需要恢复，方法如下：

CCScheduler.h

CCScheduler.cpp

在看完源码之后，来说下实际运用：

点击暂停按钮：

点击恢复按钮：

 target.

The 'target' will be  unpaused, so all schedule selectors/update will be 'ticked' again.

If the target is not  present, nothing happens.

/** Resume selectors  on a set of targets.

This can be useful  for undoing a call to pauseAllSelectors.
