推荐答案

答案是yes和no。

The answer is yes and no.

苹果并让你的应用程序来完成一个漫长的过程在后台运行。但是，如果你没有在VoIP，音乐或GPS类下跌，那么你不能在后台运行。

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，如果你要发送一些数据到服务器，这可能需要一些时间，那么你可以标记该进程回到执行，直到它完成（或10分钟。已通过）。

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).

有没有办法运行定时器或像任何事物的研究背景，你只能完成你开始应用在后台运行前的任务。

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.
