iphone - how to get coordinates from the total address of the content?

Question

I am getting total address and coordinates of the location address but I need only coordinates to show on the google map. How is it possible in iPhone?

- (void)geocode {
    [SVGeocoder geocode:addressField.text
             completion:^(NSArray *placemarks, NSError *error) {
                 UIAlertView *alertView;

                 if(!error && placemarks) {
                     SVPlacemark *placemark = [placemarks objectAtIndex:0];

                     NSLog(@"%@",placemarks);
                     alertView = [[UIAlertView alloc] initWithTitle:@"Placemark Found!" message:[placemark description] delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
                 } else {
                     alertView = [[UIAlertView alloc] initWithTitle:@"Error" message:[error description] delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
                 }

                 [alertView show];
                 [alertView release];
             }];

the response of the geocoded

"{ address = { City = Nalgonda; Country = India; CountryCode = IN; State = "Andhra Pradesh"; }; coordinate = { latitude = "17.05239"; longitude = "79.26718"; };
formattedAddress = "Nalgonda, Andhra Pradesh, India"; }"

Try this

- (CLLocationCoordinate2D) geoCodeUsingAddress:(NSString *)address
{
   double latitude = 0, longitude = 0;
   NSString *esc_addr =  [address stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
   NSString *req = [NSString stringWithFormat:@"http://maps.google.com/maps/api/geocode/json?sensor=false&address=%@", esc_addr];
   NSString *result = [NSString stringWithContentsOfURL:[NSURL URLWithString:req] encoding:NSUTF8StringEncoding error:NULL];
   if (result) {
        NSScanner *scanner = [NSScanner scannerWithString:result];
        if ([scanner scanUpToString:@""lat":" intoString:nil] && [scanner scanString:@""lat":" intoString:nil]) {
          [scanner scanDouble:&latitude];
          if ([scanner scanUpToString:@""lng":" intoString:nil] && [scanner scanString:@""lng":" intoString:nil]) {
              [scanner scanDouble:&longitude];
          }
        }
    }
   CLLocationCoordinate2D center;
   center.latitude = latitude;
   center.longitude = longitude;
   return center;
}
