Thanks. Yeah maybe that's a better convention.
I typically use _parameter for methods because I don't like putting
_ivar in class definitions. I'd rather be able to do this:
size.width = _size.width; instead of the other way around. To me the
ivars in a class are already private (unless they're exposed through a
@property). So putting _ivar is like declaring private twice.
I guess that's just always been my preference. For me it comes from
working with java or actionscript, where you can declare an ivar as
"private var something:String". So declaring "private var
_something:String" is like saying "private private var
something:String"
oh well!
