Re: ObjC Method naming

Does this mean that I could write my method calls as:

Would it be acceptable without any parameter names, just commas? Or, do I
have to use colons?

[myRect setWidth:10.0 :10.5];

I think you have to use colons, except when using an indefinite number of arguments (like printf and scanf).

Just trying to get as close to a c++ style calling structure as possible
since that's the way my brain's wired right now. Fewer keystrokes is
better.

Yes, but more verbosity helps making the code more readable (this isn't the obfuscating C contest!)

- (void)setWidth:(float)a height:(float)b;

vs.

- (void)set:(float)a :(float)b;

or

#define f float
#define v void
-(v)s:(f)a:(f)b;

;-)

Also, what does the minus sign ("-") mean in the declaration? I've seen the
plus sign used also. What's the difference? All it says in the docs is
"you could also use the plus sign..." but doesn't follow up with any meaning
behind it.

+ is called "static" in C++. Isn't not really the same, since in ObjC there's one class object (one global instance) that's accessed this way, but you can treat it like static.

And when I declare a method, do I HAVE to declare it with
parameter names or can I leave them out?

Ex.
- (void) setWidth:(float) w height:(float) h

Don't think so, but I've never tried.
