CLGeocoder Multiple Addresses? - objective-c

Question

I need to geocode two different addresses but I need to have the results inside the same scope/method. How can I direct the same variables location1 and location2 inside the same block.
Here is my current code...
- (IBAction)calculateDistance {
[textFieldDestination resignFirstResponder];
NSString *origin = [textFieldOrigin text];
if (origin) {
CLGeocoder *geoCode = [[CLGeocoder alloc] init];
[geoCode geocodeAddressString:origin completionHandler: ^(NSArray *placemarks, NSError *error) {
if (!error) {
CLPlacemark *place = [placemarks objectAtIndex:0];
CLLocation *location = place.location;
CLLocation *location1 = [[CLLocation alloc] initWithLatitude:location.coordinate.latitude longitude:location.coordinate.longitude];
} else {
NSString *string = [NSString stringWithFormat:#"%# - also make sure you have inputted a valid city", [error localizedDescription]];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Error" message:string delegate:self cancelButtonTitle:#"Ok" otherButtonTitles:nil, nil];
[alert show];
}
}];
}
NSString *destination = [textFieldDestination text];
if (destination) {
CLGeocoder *geoCode2 = [[CLGeocoder alloc] init];
[geoCode2 geocodeAddressString:destination completionHandler:^(NSArray *placemarks, NSError *error) {
if (!error) {
CLPlacemark *place = [placemarks objectAtIndex:0];
CLLocation *location = place.location;
CLLocation *location2 = [[CLLocation alloc] initWithLatitude:location.coordinate.latitude longitude:location.coordinate.longitude];
} else {
NSString *string = [NSString stringWithFormat:#"%# - also make sure you have inputted a valid city", [error localizedDescription]];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Error" message:string delegate:self cancelButtonTitle:#"Ok" otherButtonTitles:nil, nil];
[alert show];
}
}];
}
CLLocationDistance distanceM = [location1 distanceFromLocation:location2]; // obviously error so you can see that I need location1 and location2 in the same block.... but how!?
[metreDistance setText:[NSString stringWithFormat:#"%f", distanceM]];
}

I found out how to accomplish this. For each geocoding block, I directed to a method that had specific parameters. Pretty simple, just needed to use logic!
