Variable number of method parameters in Objective C - Need an example

Question

From Objective C Programming Guide (Under the "Object Messaging" section),

Methods that take a variable number of parameters are also possible,

Answer 1

You can see this link.

In your header file define the methods with three dots at the end

-(void)yourMethods:(id)string1,...;

And in you implementation file write the methods body

-(void)yourMethods:(id)string1, ...{

    NSMutableArray *arguments=[[NSMutableArray alloc]initWithArray:nil];
    id eachObject;
    va_list argumentList;
    if (string1) 
    {
        [arguments addObject: string1];
        va_start(argumentList, string1); 
        while ((eachObject = va_arg(argumentList, id)))    
        {
             [arguments addObject: eachObject];
        }
        va_end(argumentList);        
     }
    NSLog(@"%@",arguments);
}

Now call your method

[self yourMethods:@"ab",@"cd",@"ef",@"gf",nil];

NOTE: remember to put nil at the end
