iPhone核心位置CLLocationManager更新率 [英] iPhone Core Location CLLocationManager update rate

问题描述

您是否可以为CLLocationManager设置恒定的时间更新速率，以强制其连续每10秒更新一次位置？我知道距离过滤器的用法，但是如果出现问题并且位置未更新怎么办？谢谢！

Can you set up a constant time update rate for CLLocationManager to force it update locations like every 10 seconds continuously? I know the usage of the distance filter but what if something went wrong and the location is not updated? Thanks!

推荐答案

无法控制更新率。您可以设置一个计时器，然后关闭更新，直到计时器结束。这是避免使用过多电源的常用方法。

It's not possible to control the update rate. You can set a timer, then turn off the updates until the timer ends. This is the usual thing to do to avoid using too much power.

如果出现问题，则委托方法 locationManager会通知您： didFailWithError：

If there's a problem, you will be informed by the delegate method locationManager:didFailWithError:

这是一篇不错的文章，显示了如何过滤错误的CoreLocation读数：
