Question

Is there a way to turn a longitude/latitude location (as returned by Core Location) into an address (street and city)?

Answer 1

The best way is using reverse geocoding, which is available in CLGeocoder class. To get human readable address from geoposition, you have to use reverseGeocodeLocation method.

Here is small sample:

-(NSString *)getAddressFromLocation:(CLLocation *)location {
    NSString *address;
    CLGeocoder *geocoder = [[CLGeocoder alloc] init];
    [geocoder reverseGeocodeLocation:location completionHandler:^(NSArray *placemarks, NSError *error)
     {
         if(placemarks && placemarks.count > 0)
         {
             CLPlacemark *placemark= [placemarks objectAtIndex:0];

             address = [NSString stringWithFormat:@"%@ %@,%@ %@", [placemark subThoroughfare],[placemark thoroughfare],[placemark locality], [placemark administrativeArea]];

             NSLog(@"%@",address);
         }

     }];

    [geocoder release];
    return address;
}
