I don't think anyone assumed that it was. We're just a bit surprised
at what you wrote.
My original code came from the Objective C Pocket Reference by Duncan
and and the C Programming Language by K and R. Placing multiple
parameters in a function (or method) separated by commas is the
ordinary c approach. Others on the cocoa list, and in the Apple doc,
had stated that support for the ordinary c language is part of Cocoa.
I think you've got the wrong end of the stick.
Support for the ordinary C language is part of Objective-C. Cocoa is
just a set of frameworks you can use with Objective-C. Methods, since
they are not a part of the C language, use Objective-C syntax, which
uses colons rather than commas, primarily because it supports named
arguments (a single colon with no name is just an argument with a blank
name).
Some methods do, in fact, use commas, but only if they take a variable
number of arguments (e.g. NSString's +stringWithFormat: method); this
does seem somewhat inconsistent, and is probably an artefact of the
original implementation of Objective-C.
Accordingly, it just seems to me that this approach should be
supported in Cocoa.
It is, for C functions. But Objective-C isn't part of C (rather, the
other way around).
Kind regards,
Alastair.
