我已阅读以下链接: http://developer.apple.com/mac/library/qa/qa2004 /qa1340.html

I have read following link:http://developer.apple.com/mac/library/qa/qa2004/qa1340.html

这仅是关于获取通知，但不确定是否有任何方法可以将系统从睡眠中唤醒?

this only talk about getting notification , but not sure is there any way to wake system from sleep?

我很感谢这些信息的线索...

I appreciate some thread to the information...

更新:

Update:

根据我尝试使用IOPMSchedulePowerEvent的建议

As per the suggestion I tried with IOPMSchedulePowerEvent

我使用的代码:

NSCalendarDate  *timeIntervalSinceNow = [NSCalendarDate dateWithTimeIntervalSinceNow:40];
IOReturn result = IOPMSchedulePowerEvent ((CFDateRef)timeIntervalSinceNow, NULL, CFSTR(kIOPMAutoWake));

结果:

如果MacBook主机盖关闭，它将失败

It fails in MacBook if lid closed

我做错了什么或任何解决方案吗?

Am I doing some thing wrong or Any solution?

推荐答案

您可以通过电源管理器使用IOPMSchedulePowerEvent安排唤醒事件.您也许可以安排立即唤醒. pmset 是命令行电源管理器的包装器.在某些情况下，您还可以使用IOCancelPowerChange防止睡眠.

You can schedule wake up events with IOPMSchedulePowerEvent through the power manager. You may be able to schedule an immediate wake up. pmset is a command line wrapper for the power manager. You can also prevent sleep with IOCancelPowerChange in certain cases.

通过生成鼠标或按键事件，您可以防止睡眠或唤醒.生成事件的一种方法是使用CGPostKeyboardEvent.

You may be able to prevent sleep or wake up by generating a mouse or key event. One way to generate events is with CGPostKeyboardEvent.

正常睡眠不同于翻盖式封闭睡眠.要影响后者，您必须编写 Insomnia 之类的内核扩展.

Normal sleep is different from clamshell closed sleep. To affect the latter you must write a kernel extension like Insomnia.
