问题
I was wondering if we can get the source type of the current location in iOS. I didn't find any reference nor in CLLocationManager neither in CLLocation.
I've found the same question here in SO, but for Android:
- Is it possible to know my location came from gps or glonass?
- Android. How to know if location detected is from GPS or Network provider
The second one has an answer that says if the accuracy is smaller than 30 meters, than it is using GPS. But I don't know if we really can assume that.
