Objective-c - Passing in variables to a variable-length method

Question

I\'ve got an array with items, and I want to pass these in to a variable-length method. How do you do that?

I.e., I\'ve got this (for example):

NSArr         


        

Answer 1

- (id) initWithTitle:(NSString *)title message:(NSString *)message delegate:(id)delegate cancelButtonTitle:(NSString *)cancelButtonTitle otherButtonTitles:(NSString *)otherButtonTitles ...
{
    va_list args;
    va_start(args, otherButtonTitles);
    for (NSString *arg = otherButtonTitles; arg != nil; arg = va_arg(args, NSString*))
    {
        //do something with nsstring
    }
    va_end(args);
}

You could also just make an argument in your functions that accepts an array (easy solution)

Anyway the ... notation is for a variable amount of arguments at the end of a function.
