SVGeocoder is a simple Cocoa wrapper for the Google Geocoding Service. It allows you to quickly geocode and reverse-geocode addresses and coordinates. It is block-based, uses NSURLConnection internally as well as JSONKit (included in package). Make sure you read the Google Geocoding Service Terms of Service before using SVGeocoder.


  • Drag the SVGeocoder/SVGeocoder folder into your project.
  • Add the CoreLocation, MapKit and AddressBook frameworks to your project.


Using the Geocoding API

In it’s simplest form, geocoding an address is as simple as:

[SVGeocoder geocode:addressString
         completion:^(NSArray *placemarks, NSError *error) {
             // do something with placemarks, handle errors

Where placemarks is an array of SVPlacemark objects (see more about that below).

Additionally, you can use Google Geocoding API’s region and bounds parameters to fine-tune your search:

+ (SVGeocoder*)geocode:(NSString *)address bounds:(MKCoordinateRegion)bounds completion:(void (^)(NSArray *placemarks, NSError *error))block;
+ (SVGeocoder*)geocode:(NSString *)address region:(NSString *)region completion:(void (^)(NSArray *placemarks, NSError *error))block;

Using the Reverse Geocoding API

[SVGeocoder reverseGeocode:CLLocationCoordinate2DMake(45.53264, -73.60518)
                completion:^(NSArray *placemarks, NSError *error) {
                    // do something with placemarks, handle errors

Cancelling requests

Make sure you cancel requests for which the user isn’t waiting on anymore by keeping a pointer to your SVGeocoder object and calling cancel on it. In all cases, the request will time out after 20s.

About the SVPlacemark object

SVPlacemark is basically an MKPlacemark subclass but with a coordinate property. Here’s what an SVPlacemark object looks like:

	address = {
		Country = Canada;
		CountryCode = CA;
		State = Quebec;
		Street = "3456 Rue Denis";
		ZIP = "J0K 1S0";
	coordinate = {
		latitude = "46.01529";
		longitude = "-73.76997";
	formattedAddress = "3456 Rue Saint-Denis, Montreal, QC H2L 4S9, Canada"
