Integrating with Stripe (iOS)

If you haven't already, follow the "Importing DyScan" and "Interfacing DyScan" steps in the General Integration Guide.

Stripe 16.0.3 and higher

The DyScan output can then be converted into an STPPaymentMethodCardParams object that can be passed to a STPPaymentCardTextField or a custom Stripe class by editing the extension functions in the following manner.

extension ExampleViewController: DyScanViewControllerDelegate{
    func onFailure(_ paymentViewController: DyScanViewController!, reason: DyScanExitReason) {
        paymentViewController.dismiss(animated: true){
        
        // CardFieldViewController is a view controller containing an
        // STPPaymentCardTextField called cardField
        let viewController = CardFieldViewController()
        let navigationController = UINavigationController(rootViewController: viewController)
        self.present(navigationController, animated: true, completion: nil)
        }
    }
    
    func onSuccess(_ cardInfo: DyScanCreditCardInfo!, in paymentViewController: DyScanViewController!) {
        
        // CardFieldViewController is a view controller containing an
        // STPPaymentCardTextField called cardField
        let viewController = CardFieldViewController()
        let navigationController = UINavigationController(rootViewController: viewController)

        paymentViewController.dismiss(animated: true){
        
        if let info = cardInfo {
            let card = STPPaymentMethodCardParams()
            card.number = info.cardNumber
            if(info.expiryMonth > 0){
                card.expMonth = NSNumber(value: info.expiryMonth)
                card.expYear = NSNumber(value: info.expiryYear)
            }
            viewController.cardField.cardParams = card
        }
        self.present(navigationController, animated: true, completion: nil)
    }
}

Stripe 16.0.2 and lower

The DyScan output can then be converted into an STPCardParams object that can be passed to a STPPaymentCardTextField or a custom Stripe class by editing the extension functions in the following manner.

extension ExampleViewController: DyScanViewControllerDelegate{
    func onFailure(_ paymentViewController: DyScanViewController!, reason: DyScanExitReason) {
        paymentViewController.dismiss(animated: true){
        
        // CardFieldViewController is a view controller containing an
        // STPPaymentCardTextField called cardField
        let viewController = CardFieldViewController()
        let navigationController = UINavigationController(rootViewController: viewController)
        self.present(navigationController, animated: true, completion: nil)
        }
    }
    
    func onSuccess(_ cardInfo: DyScanCreditCardInfo!, in paymentViewController: DyScanViewController!) {
        
        // CardFieldViewController is a view controller containing an
        // STPPaymentCardTextField called cardField
        let viewController = CardFieldViewController()
        let navigationController = UINavigationController(rootViewController: viewController)

        paymentViewController.dismiss(animated: true){
        
        if let info = cardInfo {
            let card = STPCardParams()
            card.number = info.cardNumber
            if(info.expiryMonth > 0){
                card.expMonth = info.expiryMonth
                card.expYear = info.expiryYear
            }
            viewController.cardField.cardParams = card
        }
        self.present(navigationController, animated: true, completion: nil)
    }
}
