Question

Is it possible to do that this way:

- (void) setList:(id) firstObj,...
{
    va_list args;
    va_start(args,firstObj);
    list = [[NSArray alloc] initWithObjects:args]; // Compile error
    va_end(args);
}

Answer 1

Try this:

- (void) setList:(id)firstObj, ... NS_REQUIRES_NIL_TERMINATION
{
    va_list args;
    va_start(args, firstObj);
    list = [[NSMutableArray alloc] initWithObjects:firstObj, nil];
    id obj;
    while ((obj = va_arg(args, id)) != nil) {
        [list addObject:obj];
    }
    va_end(args);
}
