我想在后台通过 GPS 轮询位置.因此，我们使用了 NSTimer 并在计时器滴答中执行定期检查.换句话说，我们可以在应用程序处于后台时安排 NSTimer 吗?

提前致谢

你不能定期执行任意代码，但你可以通过 startMonitoringSignificantLocationChanges 在 CLLocationManager 中.p>

I want to poll the location from GPS in the background. So we used a NSTimer and performed periodic checks in the timer tick. In other words, can we schedule NSTimer while the app is in Background?

Thanks in advance

You can't periodically execute arbitrary code, but you can get pinged on significant location changes via startMonitoringSignificantLocationChanges in CLLocationManager.
