Variable length parameters in Objective-C

How can i make a class method with variable length parameters, in Objective-C?

For example, a method like -arrayWithObjects:

  • Objective-C passing around … nil terminated argument lists
  • NSArray *array = [NSArray arrayWithObjects:@"1", @"2", @"3", nil];

    What you need is a variadic function. These functions take a flexible number of arguments, like NSLog, [NSArray arrayWithObjects:...], etc.

    See this tutorial:

    Copied from my answer here: Obj-C, trying to write an alternative to NSLog, but I want my function to concatenate like NSLog?

    Take a look at varargs, e.g.:
    Apple Technical Q&A QA1405. It shouldn’t matter whether the method is a class method or not.

    Methods that take variable arguments are known as variadic methods. The “…” is the variable argument.
    For example, your function declaration would be: - (void)specialWithX:(NSInteger)x y:(NSInteger)y, ...;
