Usage example

First step: this framework integrated with Stripe, you must install Stripe

Storyboard

Create a view set a class CreditCardFormView (preferred frame size: 300x200).
Following this you will have to go through a few simple steps outlined below in order to get everything up and running.

import Stripe
import CreditCardForm

Swift

@IBOutlet weak var creditCardForm: CreditCardFormView!

// Stripe textField
let paymentTextField = STPPaymentCardTextField()

Add the following code in the viewDidLoad function in your view controller

// Set up stripe textfield
paymentTextField.frame = CGRect(x: 15, y: 199, width: self.view.frame.size.width - 30, height: 44)
paymentTextField.translatesAutoresizingMaskIntoConstraints = false
paymentTextField.borderWidth = 0

let border = CALayer()
let width = CGFloat(1.0)
border.borderColor = UIColor.darkGray.cgColor
border.frame = CGRect(x: 0, y: paymentTextField.frame.size.height - width, width:  paymentTextField.frame.size.width, height: paymentTextField.frame.size.height)
border.borderWidth = width
paymentTextField.layer.addSublayer(border)
paymentTextField.layer.masksToBounds = true

view.addSubview(paymentTextField)

NSLayoutConstraint.activate([
paymentTextField.topAnchor.constraint(equalTo: creditCardForm.bottomAnchor, constant: 20),
paymentTextField.centerXAnchor.constraint(equalTo: view.centerXAnchor),
paymentTextField.widthAnchor.constraint(equalToConstant: self.view.frame.size.width-20),
paymentTextField.heightAnchor.constraint(equalToConstant: 44)
])

Delegate Methods

In order to use the delegate methods first set the delegate of Stripe to the parent view controller when setting it up

paymentTextField.delegate = self

After that you will be able to set up the following delegate methods inside of your parent view controller

func paymentCardTextFieldDidChange(_ textField: STPPaymentCardTextField) {
creditCardForm.paymentCardTextFieldDidChange(cardNumber: textField.cardNumber, expirationYear: textField.expirationYear, expirationMonth: textField.expirationMonth, cvc: textField.cvc)
}

func paymentCardTextFieldDidEndEditingExpiration(_ textField: STPPaymentCardTextField) {
creditCardForm.paymentCardTextFieldDidEndEditingExpiration(expirationYear: textField.expirationYear)
}

func paymentCardTextFieldDidBeginEditingCVC(_ textField: STPPaymentCardTextField) {
creditCardForm.paymentCardTextFieldDidBeginEditingCVC()
}

func paymentCardTextFieldDidEndEditingCVC(_ textField: STPPaymentCardTextField) {
creditCardForm.paymentCardTextFieldDidEndEditingCVC()
}

You should now be ready to use CreditCardForm!!
