'hostViewController must not be nil on STPPaymentContext when calling pushPaymentOptionsViewController on it - ios

Question

This is my SignUpViewController:-
import UIKit
import Firebase
import Stripe
class SignUpViewController: UIViewController {
var paymentContext = STPPaymentContext()
#IBOutlet weak var email: UITextField!
#IBOutlet weak var password: UITextField!
#IBOutlet weak var passwordConfirm: UITextField!
#IBAction func signUpAction(_ sender: Any) {
if password.text != passwordConfirm.text {let alertController = UIAlertController(title: "Password Incorrect", message: "Please re-type password", preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)
}else{
Auth.auth().createUser(withEmail: email.text!, password: password.text!){ (user, error) in if error == nil {
self.performSegue(withIdentifier: "signupToHome", sender: self)
}
else{
let alertController = UIAlertController(title: "Error", message: error?.localizedDescription, preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)
}
}
}
}
#IBAction func userIconClicked(_ sender: Any){
let userSheet = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet)
let logout = UIAlertAction(title: "Logout", style: .default) { (action) in
// Logout
do {
try Auth.auth().signOut()
} catch {
debugPrint(error.localizedDescription)
}
}
let manageCards = UIAlertAction(title: "Manage Credit Cards", style: .default) { (action) in
// Display Stripe Widget
self.paymentContext.pushPaymentOptionsViewController()
}
let manageBanks = UIAlertAction(title: "Manage Bank Accounts", style: .default) { (action) in
// Manage Bank Accounts
}
let close = UIAlertAction(title: "Close", style: .cancel)
userSheet.addAction(manageCards)
userSheet.addAction(manageBanks)
userSheet.addAction(logout)
userSheet.addAction(close)
present(userSheet, animated: true)
}
func setupStripe() {
Wallet.instance.customerContext = STPCustomerContext(keyProvider: StripeApiClient())
let config = STPPaymentConfiguration.shared
paymentContext = STPPaymentContext(customerContext: Wallet.instance.customerContext,
configuration: config(),
theme: .default())
paymentContext.hostViewController = self
}
}
This what it is in the simulator:--
The "Button" on the right-hand-upper-corner is linked to "#IBAction func userIconClicked(_ sender: Any)". When I click on this button, the following shows up on the simulator: -
Now, when I click on "Manage Credit Cards", it shows error in the AppDelegate - - Thread 1: "hostViewController must not be nil on STPPaymentContext when calling pushPaymentOptionsViewController on it. Next time, set the hostViewController property first! as shown in the screenshot below:-
What am I doing wrong ?
Edit 1: after humnoz comment, I called "setupStripe()", still same error -
import UIKit
import Firebase
import Stripe
class SignUpViewController: UIViewController {
var paymentContext = STPPaymentContext()
#IBOutlet weak var email: UITextField!
#IBOutlet weak var password: UITextField!
#IBOutlet weak var passwordConfirm: UITextField!
#IBAction func signUpAction(_ sender: Any) {
if password.text != passwordConfirm.text {let alertController = UIAlertController(title: "Password Incorrect", message: "Please re-type password", preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)
}else{
Auth.auth().createUser(withEmail: email.text!, password: password.text!){ (user, error) in if error == nil {
self.performSegue(withIdentifier: "signupToHome", sender: self)
}
else{
let alertController = UIAlertController(title: "Error", message: error?.localizedDescription, preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)
}
}
}
}
func viewDidLoad(_ animated: Bool) {
Auth.auth().addStateDidChangeListener { (auth, user) in
// If there is a user logged in, stay here on homeVC
// else, take them to the login page.
if user == nil {
let loginVC = LoginRegisterVC()
loginVC.modalPresentationStyle = .fullScreen
self.present(loginVC, animated: true)
} else {
UserManager.instance.getCurrentUser {
self.setupStripe()
}
}
}
}
#IBAction func userIconClicked(_ sender: Any){
let userSheet = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet)
let logout = UIAlertAction(title: "Logout", style: .default) { (action) in
// Logout
do {
try Auth.auth().signOut()
} catch {
debugPrint(error.localizedDescription)
}
}
let manageCards = UIAlertAction(title: "Manage Credit Cards", style: .default) { (action) in
// Display Stripe Widget
self.paymentContext.pushPaymentOptionsViewController()
}
let manageBanks = UIAlertAction(title: "Manage Bank Accounts", style: .default) { (action) in
// Manage Bank Accounts
}
let close = UIAlertAction(title: "Close", style: .cancel)
userSheet.addAction(manageCards)
userSheet.addAction(manageBanks)
userSheet.addAction(logout)
userSheet.addAction(close)
present(userSheet, animated: true)
}
func setupStripe() {
Wallet.instance.customerContext = STPCustomerContext(keyProvider: StripeApiClient())
let config = STPPaymentConfiguration.shared
paymentContext = STPPaymentContext(customerContext: Wallet.instance.customerContext,

}
}
