Hi there, is this is the method that you refer to https://stripe.dev/stripe-ios/stripepayments/documentation/stripepayments/stpauthenticationcontext/authenticationcontextwilldismiss(_:) ?
bronze narwhal
Yes that's the one
runic sage
Can you share with me the relevant code?
Are you using the latest version of stripe ios SDK? https://github.com/stripe/stripe-ios/blob/master/CHANGELOG.md#23290-2024-08-05
bronze narwhal
class AddCreditCardHostingController:
UIHostingController<AddCreditCardView<DefaultAddCreditCardViewModel>>,
STPAuthenticationContext
{
...
// MARK: - Conformance: STPAuthenticationContext
func prepare(forPresentation completion: @escaping STPVoidBlock) {
loadingDelegate?.setLoadingIndicatorState(.hidden, in: self)
DispatchQueue.main.async {
completion()
}
}
func authenticationPresentingViewController() -> UIViewController {
return self
}
func authenticationContextWillDismiss(_ viewController: UIViewController) {
loadingDelegate?.setLoadingIndicatorState(.loading(), in: self)
}
Yep, using the latest version. I've tried with a UIViewController and UIHostingController but have had no luck
runic sage
Ok, and how do you pass AddCreditCardHostingController to Stripe SDK?
bronze narwhal
I think it's via the STPAuthenticationContext protocol, we then provide this to the SDK via:
STPPaymentHandler.shared().confirmSetupIntent(
intentParameters,
with: inputDetails.authenticationContext
) {
Can you put some logs in your code to confirm inputDetails.authenticationContext is an instance of AddCreditCardHostingController ?
bronze narwhal
if let hostingController = inputDetails.authenticationContext as? AddCreditCardHostingController {
// This is hit
print("Is hosting controller")
}
STPPaymentHandler.shared().confirmSetupIntent(
intentParameters,
with: inputDetails.authenticationContext
) { status, intent, _ in
...
}
I added a check to ensure the context was the hosting controller, the print statement seems to be hit
runic sage
OK, do you have any code that might change the value of inputDetails.authenticationContext ?
bronze narwhal
No, I don't think so, we provide the context straight to the SDK when we attempt to link a credit card funding source.
runic sage
I mean any code that might change the value of inputDetails.authenticationContext after calling STPPaymentHandler.shared().confirmSetupIntent ?
bronze narwhal
No, not that I can see. This is our implementation:
func authorizePaymentMethod() async throws -> String {
guard let inputDetails, let intentParameters else {
throw FundingSourceServiceError.invalidConfig
}
let setupIntent: STPSetupIntent = try await withCheckedThrowingContinuation { continuation in
DispatchQueue.main.async {
STPPaymentHandler.shared().confirmSetupIntent(
intentParameters,
with: inputDetails.authenticationContext
) { status, intent, _ in
switch status {
case .succeeded:
guard let intent = intent else {
let error = FundingSourceServiceError.internalError(cause: "Intent is nil on success")
return continuation.resume(throwing: error)
}
return continuation.resume(returning: intent)
case .failed:
let error = FundingSourceServiceError.internalError(cause: "Extra Authorization failed")
return continuation.resume(throwing: error)
case .canceled:
let error = FundingSourceServiceError.internalError(cause: "Authorization cancelled")
return continuation.resume(throwing: error)
}
}
}
}
guard let paymentMethodId = setupIntent.paymentMethodID else {
throw FundingSourceServiceError.internalError(cause: "Invalid intent, no payment method found")
}
return paymentMethodId
}
Can you share with me a sample project that I can run and reproduce?
bronze narwhal
Unfortunately I work for a company & the codebase is private, I'm happy to provide you with any code snippets however
