How to subclass an UIButton to pass multiple NSString parameters via addTarget:action:forControlEvents

I have to programmatically define (without using any IBAction) a UIButton that when tapped gets the values of 3 NSString parameters and executes a Segue. The method used for executing the Segue is called via:

[myButton addTarget:self action:@selector(myButtonTapped:) forControlEvents:UIControlEventTouchUpInside]; And then executed as:

-(void)myButtonTapped { [self performSegueWithIdentifier:@"showNewFromOld" sender:self];}

I understand that the best solution would be to subclass the UIButton (myButton in my case) in order to pass via the sender the 3 NSString. Unfortunately I have some doubts on how to implement this as I get confused on how to call and what to pass to the subclass. I would really appreciate some help from the community on this!
