OPPaymentCardCvvViewDelegate

@objc
public protocol OPPaymentCardCvvViewDelegate : NSObjectProtocol

Defines the interface that should be implemented to receive updates from instances of OPPaymentCardCvvView. Each callback method is optional so you only need to implement the ones you need.

Important

There are two versions of each callback method. One version contains a reference to the view and can be used if you are implementing these callbacks in your UI layer. If implementing callbacks in a data layer it is recommended to implement the versions that do not contain a reference to a view.
