コンテンツの合計アドレスから座標を取得する方法は？

Question

ロケーションアドレスの合計アドレスと座標を取得していますが、Googleマップに表示する座標だけが必要です。 iPhoneではどのように可能ですか？

- (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]; 
      }];

- (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; 
}
