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

Question

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];

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