I saw from another question here : Determine iPhone user's country that it is possible to get the current country the user of the iPhone is in.
And that is quite convenient for many uses. However, would it be possible to go even deeper and infer from iOS (if it has the information) which state or city the user is in as well?
I suppose reverse geocoding services would be the next step if things weren't possible.. Are there even such things as a reverse geocoding service you can hire for your app though?
I would start with the
CLReverseGeocoder
class.This stackoverflow question gets the current city and can probably be adapted for your use.
