iphone - 核心位置中的 kCLLocationAccuracyBestForNavigation 设置是否会改善步行的定位服务？

Question

我有一个应用程序需要保留有关用户行走位置的非常精确的数据。在这种情况下，启用 kCLLocationAccuracyBestForNavigation 而不是 kCLLocationAccuracyBest 会给我带来什么好处吗？谢谢。

Answer 1

与 kCLLocationAccuracyBest 相比，kCLLocationAccuracyBestForNavigation 更适合您想要实现的目标。

不选择 BestForNavigation 的唯一原因是 iOS<4 设备的支持。

顺便说一句，kCLLocationAccuracyBestForNavigation 也会消耗电池......但相对于其他，不超过 20%(根据我的个人经验)。

As the boys in Apple said:

kCLLocationAccuracyBestForNavigation Use the highest possible accuracy and combine it with additional sensor data. This level of accuracy is intended for use in navigation applications that require precise position information at all times and are intended to be used only while the device is plugged in.
