unlimited reverse Geocoding request

I have implemented an application which can import a GPX file and it contains many lat/long coordinates (several hundred).

My application performs a reverse geocoding for each lat/long. I want to display in a tableview all lat/long with their address (which will be ordered by country and town).

I'm performing only one geocoding request at a time (like it's described in Apple's documentation of reverseGeocodeLocation() in Core Location. When I get the answer of a geocoding request then I request the next one and then until I have resolved all my Lat/Long.

Unfortunately when I have resolved around 40 Lat/Long, the reverseGeocodeLocation() raises an error (CLError.network) and then I need to wait 60 seconds before the resolve the next ones etc...

I have several questions: - Is there a way to go faster? because if I have 800 lat/long it will takes around 20 minutes (800/40) * 60 = 1200 seconds (it's very long for an App running on a iPhone) - Even if I don't perform improvements on the rate, is there a risk that if I have many users then Apple will forbid my App because the number of Geocoding request will be too high?

Thanks for your feedback Regards,

Sebastien

The docs say "Send at most one geocoding request for any one user action". So I would say sending 800 requests for a single user action definitely runs the risk of you getting rejected for abusing the geocoding APIs. - dan
I agree but do you see others options (free)? - sebastien
did you find the solution? - Gringo Russo

Is the GPX file static or will it be changing for every user/download? If static, then maybe just reverse geocode all the coords beforehand?

Alternately, look for a different service to do reverse geocoding.
