6 minute interval timer

efficiency of the reactor model development is higher than the direct use of IO multiplexing, it is usually single-threaded, the design goal is to use a single CPU all the resources, but also has the advantage that each event processing in many cases can not consider the shared resources of mutually exclusive access. But the shortcomings are also obvious, now the hardware development, has no longer follow Moore's law, the CPU frequency is constrained by the material limit no longer have a big p

;setPosition(ccp(s.width / 2, s.height / 2));addChild(pLabel);schedule(schedule_selector(Schedule::showTimebyLabel), 1.0f); Create a label and display the current system time by default. Then, use the schedule function to call our own function every second. void Schedule::showTimebyLabel(float dt){time(tt);now = localtime(tt);pLabel->setString(CCString::createWithFormat("%d:%d:%d",now->tm_hour,now->tm_min,now->tm_sec )->getCString());} After running the command, you can see that the
