There is no forward geocoding class on iOS. And it’s no secret that MKReverseGeocoder is a pain in the butt and returns with an error half of the time. So I took the opportunity to write SVGeocoder, a simple geocoder and reverse geocoder for iOS. My first GitHub release!
SVGeocoder requires the CoreLocation, MapKit and AddressBook frameworks as well as the (included) TouchJSON parser by Jonathan Wight. It also uses the Google Geocoding API so make sure you read theirTerms of Service before using SVGeocoder.
Using the Geocoder
NSString * addressString = @"3245 St-Denis, Montreal"SVGeocoder * geocodeRequest = [[ SVGeocoder alloc ] initWithAddress: addressString ];[ geocodeRequest setDelegate: self ];[ geocodeRequest startAsynchronous ];
Using the Reverse Geocoder
CLLocationCoordinate2D coordinate = CLLocationCoordinate2DMake ( 45.54181 , - 73.62928 );SVGeocoder * rGeocoderRequest = [[ SVGeocoder alloc ] initWithCoordinate: coordinate ];[ rGeocoderRequest setDelegate: self ];[ rGeocoderRequest startAsynchronous ];
Best of all, SVGeocoderDelegate returns an MKPlacemark object just like with MKReverseGeocoder:
- ( void ) geocoder: ( SVGeocoder * ) geocoder didFindPlacemark: ( MKPlacemark * ) placemark ;- ( void ) geocoder: ( SVGeocoder * ) geocoder didFailWithError: ( NSError * ) error ;
