Counter across 3 View Controllers?

Need a way to make a counter work across at least 3 View Controllers.

One view controller has an -(IBAction)plus1 button and an -(IBAction)plus 0 button.

 

Those buttons segue to the next view controller, that has an -(IBAction)plus2 button and an -(IBAction)plus 0 button.... etc.

 

Each segues and adds all button clicks through to the last view controller with an IBOutlet UILabel *count text label.

 

I got this to work on one view controller. Can't figure out how to make it work across 3VCs. Someone suggested Singleton?

Thanks for any thoughts.

 

Thanks JDL55
