Objective C method with parameters

I needed to create a new method with 2 argument.  I also need to call this method.

Easier said then done.  Rather than try to add to the already volumnious documentation out there regarding objective c method name and parameters, here is what i did:

My declaration.  It's a method called "updateLatLong" that has 2 arguments (a longitude and latitude)

-(void)updateLatLong:(NSString *)latitude  longitude:(NSString *)longitude;

Here's how I called it (a little verbose since I had to convert doubles to Strings)

        NSMutableString *mylat = [[[NSMutableString alloc] init] autorelease];

        [mylat appendFormat: @"", fabs(newLocation.coordinate.latitude)];

        NSMutableString *mylong = [[[NSMutableString alloc] init] autorelease];
        [mylong appendFormat: @"", fabs(newLocation.coordinate.latitude)];

        [self.delegate updateLatLong:mylat longitude:mylong];

Notice how the first agrument (latitude) is passed by not named.  Crazy!
