The C99 standard states that conforming compilers must support at
least 127 function arguments. I don't know if GCC enforces a limit
above this, but if it doesn't, then the maximum number of arguments is
only limited by the available stack space at run time. I assume
Objective-C would support the same functionality, but I'm sure someone
will correct me if I'm wrong. (Note that Obj-C uses two hidden
arguments when sending messages: self and _cmd. So in the case that
GCC supports the bare minimum of 127 function arguments, when sending
messages with Objective-C, you'd only be able to use 125. In practice
though, I think we all have a better chance of winning the lottery,
getting struck by lightning, and contracting swine flu all in the same
night, than creating a genuinely useful function that takes 128
arguments.)

Probably my own; I'm relentless when it comes to clarity in method,
class and variables names. I've got a class name that's 55 characters,
a category (filename) that's 51, and a variable name that's (drumroll)
63 characters. Of course, it's arguable that after a certain length,
it's counterproductive. I think I'm just crazy...
