推荐答案

答案是肯定的，也不是.

The answer is yes and no.

Apple 确实允许您的应用程序在后台完成一个冗长的过程.但是，如果您不属于 VoIP、音乐或 GPS 类别，那么您将无法在后台运行.

Apple does allow you app to complete a lengthy process in the background. But if you does not fall in the Voip, music or GPS category then you can't run in background.

例如，如果您想向服务器发送一些数据，这可能需要一些时间，那么您可以将该进程标记为返回执行，直到它完成(或 10 分钟过去).

If for example you want to send some data to a server, which could take some time, then you can mark that process to back executed until it is finished (or 10min. have passed).

你会找到一些关于在后台执行有限长度任务

You will find some about Executing a Finite-Length Task in the Background

没有办法在后台运行计时器或任何类似的东西，您只能在应用程序后台运行之前完成您启动的任务.

There is not way to run timers or any thing like that in the backgroud, you can only finish a task you started before the app is backgrounded.
