Question

In iOS 5, there is a new way to forward geocode address (converting address like 1 Infinite Loop, CA, USA to lat/lang address). More info on this is here.

Has anybody t

Answer 1

In addition to the selected answer, there is also this way for adding annotations to the mapView for forward geocoding. The CLPlacemark object can be directly cast to MKPlacemark and added to the mapview. Like this:

MKPlacemark *placemark = [[MKPlacemark alloc] initWithPlacemark:placemark];
[self.mapView addAnnotation:placemark];

Here is a full example of forward geocoding.

 NSString *address = @"1 Infinite Loop, CA, USA";
 CLGeocoder *geocoder = [[CLGeocoder alloc] init];
    [geocoder geocodeAddressString:address 
                 completionHandler:^(NSArray* placemarks, NSError* error){
                     // Check for returned placemarks
                     if (placemarks && placemarks.count > 0) {
                         CLPlacemark *topResult = [placemarks objectAtIndex:0];
                         // Create a MLPlacemark and add it to the map view
                         MKPlacemark *placemark = [[MKPlacemark alloc] initWithPlacemark:topResult];
                         [self.mapView addAnnotation:placemark];
                         [placemark release];
                     }
                     [geocoder release];
                 }];
