Something that I’ve been asked a few times is about how to incorporate reverse goecoding into iphone apps. Previously you needed to use an outside service, but with the Mapkit that functionality is now built in. For those unfamiliar with therm, reverse geocoding is the process of taking the latitude and longitude of a location, and translating that to the name of the nearest known location.
It’s now a very simple process thanks to MKReverseGeocoderDelegate.
I found a great tutorial earlier today that you can check out here:
Introduction To Mapkit iPhone OS 2.0
If you tried to implement reverse geocoding before iPhone OS 3.0 you know how much of a godsend it is.
