iOS Creating method with indifinitive amount of arguments

[exmorpheus]

I noticed some array methods like initWithObjects or arrayWithObjects allow you to keep adding arguments until you pass a null argument. So I'm wondering how I would make something similar to that. I looked at the header file in which arrayWithObjects was declared and saw this:

- (void)arrayWithObjects:(id *)firstObject, ... NS_REQUIRES_NIL_TERMINATION;

I was wondering if I could do the same with my own methods and if so, how do I call the other arguments?

In other languages you'd parse an array of arguments. You've then just got to work out what to do with it.

Use a va_list. It's how functions like printf (and the one you posted, as far as I can tell) work.
