在睡眠模式下运行iPhone应用程序 [英] Running IPhone apps while in sleep mode

问题描述

从iPhone OS 3.0开始，MotionX GPS能够在睡眠模式下继续录制GPS轨道。按下手机顶部的睡眠按钮后，应用程序将继续接收GPS坐标并进行录制。有谁知道他们怎么能这样做？我只知道在睡眠模式下继续运行音频的方法。

As of IPhone OS 3.0, MotionX GPS is able to keep recording a GPS track while in sleep mode. After you push the sleep button on top of the phone, the app continues receiving GPS coordinates and recording them. Does anyone know how they're able to do this? I'm only aware of the method to keep running audio while in sleep mode.

你必须启动一个播放的计时器每10秒响​​一次。但声音可以保持沉默。

You have to start a timer that plays a sound every 10 seconds. But the sound can be silent.
