How do I pass both latitude and longitude coordinates on button press and drop a pin on next map view?

Question

I feel like I'm getting close if someone can just help me on the last stretch!

Currently I have the following:

{
   CLLocationCoordinate2D location;
   location.latitude = (double) 44.4758;
   location.longitude = (double) -73.2125;

   str = [[NSNumber numberWithDouble:location.longitude] stringValue];

   viewController.stringToDisplay = str;
}

Now, this is passing the longitude value, but it won't of course let me include the latitude. What can I write to include both in the same line?

Thank you!

DID IT!! So happy. I pass different coordinates from a previous view based on the button pressed and am pinning those coordinates on the next view with IF statements. This is no doubt a simple thing for a programming guru, but I have no experience so I'm happy :)

-(void)viewWillAppear:(BOOL)animated

{
  CLLocationCoordinate2D location;
  NSLog(@"self.stringToDisplay = %@", self.stringToDisplay);

  if ([self.stringToDisplay isEqualToString: @"44.48, -73.21"])
  {
    location.latitude = (double) 44.4758;
    location.longitude = (double) -73.2125;

    MapViewAnnotation *newAnnotation = [[MapViewAnnotation alloc] initWithTitle:@"Burlington, VT" andCoordinate:location];
    [self.mapView addAnnotation:newAnnotation];
  }

  if ([self.stringToDisplay isEqualToString: @"51.50, -0.14"])
  {
    location.latitude = (double) 51.5010;
    location.longitude = (double) -0.1425;

    MapViewAnnotation *newAnnotation = [[MapViewAnnotation alloc] initWithTitle:@"Buckingham Palace" andCoordinate:location];
    [self.mapView addAnnotation:newAnnotation];
  }
}
