检测 iOS 设备在室内的位置
如何在室内准确定位 iOS 设备?
如果GPS在室内无法正确使用,还有什么其他方法可以在室内跟踪和定位iOS设备呢?
还有其他私有但苹果允许的 API 吗?
CoreLocation 是否完全基于 GPS?
谢谢
How can one accurately locate an iOS device indoors?
If the GPS cannot be used correctly indoors, what other way can one track and locate an iOS Device indoors?
Are there any other APIs that are private but allowed by apple?
Is CoreLocation based completely off the GPS?
Thanks

我记得,CoreLocation API 总是会返回一个位置。我不确定你是否可以将其设置在某处,但 CoreLocation 能够通过多种方式确定你的位置;
因此,如果 GPS 不可用,其他 2 个中的任何一个都可能为您提供结果(尽管不那么精确)。如果上述方法都不起作用,它可能会给你一个缓存的结果,或者你只是运气不好。
因此,不需要调用另一个API;一个 API 就足够了,并根据可用性为您做出决策。
As I recall, the CoreLocation API will always return you a location. I'm not sure if you can set it somewhere, but CoreLocation is able to establish your location in multiple ways;
So if GPS is unavailable, chances are any of the other 2 will give you a result (though not as precise). If none of the above work, it might give you a cached result or you are simply out of luck.
So, there is no need to call another API; one API will do just fine and make decisions for you based on availability.
室内精准定位目前还没有好的解决方案。 MiRAGe 对 CoreLocation 的解释是正确的。
There is no good solution for precise indoor positioning. MiRAGe is correct in his explain ation of CoreLocation.
