Does anybody know how to implement an method in objective c that will take an array of arguments as parameter such as:

[NSArray arrayWithObjects:@\"A         


        

Answer 1

Multiple arguments (also known as an arglist) can only come at the end of a method declaration. Your doSomething method would look something like this:

+ (void)doNumberOfTimes:(NSInteger)numberOfTimes withStrings:(id)firstArg, ...
{
    va_list args;
    va_start(args, firstArg);

    NSString * argString = firstArg;
    while (argString != nil)
    {
        // do something with argString here

        argString = va_arg(args, NSString *);
    }

    va_end(args);
}

To be called as follows:

[SomeClass doNumberOfTimes:2 withStrings:@"A", @"B", nil];
