Thanks, that clears things up a bit.


Would you call the method with multiple arguments the same way--with the arguments inside the method name?


For example, would you call the method


- (void)setXLocation:(double)x yLocation:(double)y


like this


[setXLocation:10 yLocation:20];

    Yeah, that's right, except your method call has no receiver, and it should. So it would have to be

    [anObject setXLocation:10 yLocation:20];

    when you want to invoke it.

      Allow me to step in here with a related question if I may. Are the tags in the argument list of the declaration, e.g. yLocation, just for readability or do they provide a way of specifying arguments in any order?
