使用CLGeocoder转发地理编码示例

Question

A directions to a working example or some guidance on how to use the forward geocoding beside the Apple Documentation. Thats pretty generic (i cant understand)

Please this would be great! Also does anyone know if they are using Google API to achieve the same or their own?

Answer 1

Found this to work, though i will post it here if someone else finds it useful.

CLGeocoder *geocoder = [[CLGeocoder alloc] init];
    [geocoder geocodeAddressString:PlaceName.text completionHandler:^(NSArray *placemarks, NSError *error) {
        //Error checking

        CLPlacemark *placemark = [placemarks objectAtIndex:0];
        MKCoordinateRegion region;
        region.center.latitude = placemark.region.center.latitude;
        region.center.longitude = placemark.region.center.longitude;
        MKCoordinateSpan span;
        double radius = placemark.region.radius / 1000; // convert to km

        NSLog(@"Radius is %f", radius);
        span.latitudeDelta = radius / 112.0;

        region.span = span;

        [mapView setRegion:region animated:YES];
    }];
