Scan overlay background color

[alexandermcpherson]

Not an issue but if anyone would like to know how to change the BG color of the CardIOPaymentViewController use the below where cardIOVC is an instance of CardIOPaymentViewController (CardIOPaymentViewController is a subclass of UINavigationController so just ask it for the the controllers contained in its hierarchy.. in this case I pull out the first VC it finds which happens to be a CardIOViewController and from here I set the appropriate background color)

cardIOVC?.viewControllers.first?.view.backgroundColor = UIColor(red: 87/255, green: 166/255, blue: 216/255, alpha: 1)
