STPPaymentContext

@interface STPPaymentContext : NSObject <STPAuthenticationContext>

An STPPaymentContext keeps track of all of the state around a payment. It will manage fetching a user’s saved payment methods, tracking any information they select, and prompting them for required additional information before completing their purchase. It can be used to power your application’s payment confirmation page with just a few lines of code.

STPPaymentContext also provides a unified interface to multiple payment methods - for example, you can write a single integration to accept both credit card payments and Apple Pay.

STPPaymentContext saves information about a user’s payment methods to a Stripe customer object, and requires an STPCustomerContext to manage retrieving and modifying the customer.

  • This is a convenience initializer; it is equivalent to calling initWithCustomerContext:customerContext configuration:[STPPaymentConfiguration sharedConfiguration] theme:[STPTheme defaultTheme].

    Declaration

    Objective-C

    - (nonnull instancetype)initWithCustomerContext:
    (nonnull STPCustomerContext *)customerContext;

    Swift

    init(customerContext: STPCustomerContext)

    Parameters

    customerContext

    The customer context the payment context will use to fetch and modify its Stripe customer. - see: STPCustomerContext.h

    Return Value

    the newly-instantiated payment context

  • The Stripe ID of a payment method to display as the default pre-selected option.

    Customer doesn’t have a default payment method property, but you can store one (in its metadata, for example) and set this property accordingly.

    Note

    Set this property immediately after initializing STPPaymentContext, or call retryLoading afterwards.

    Declaration

    Objective-C

    @property (readwrite, copy, nonatomic, nullable) NSString *defaultPaymentMethod;

    Swift

    var defaultPaymentMethod: String? { get set }

  • The user’s currently selected payment option. May be nil.

    Declaration

    Objective-C

    @property (readonly, nonatomic, nullable) id<STPPaymentOption>
    selectedPaymentOption;

    Swift

    var selectedPaymentOption: STPPaymentOption? { get }
    Show on GitHub

  • The available payment options the user can choose between. May be nil.

    Declaration

    Objective-C

    @property (readonly, nonatomic, nullable)
    NSArray<id<STPPaymentOption>> *paymentOptions;

    Swift

    var paymentOptions: [STPPaymentOption]? { get }

  • The user’s currently selected shipping method. May be nil.

    Declaration

    Objective-C

    @property (readonly, nonatomic, nullable)
    PKShippingMethod *selectedShippingMethod;

    Swift

    var selectedShippingMethod: PKShippingMethod? { get }

  • An array of STPShippingMethod objects that describe the supported shipping methods. May be nil.

    Declaration

    Objective-C

    Swift

    var shippingMethods: [PKShippingMethod]? { get }
    Show on GitHub

  • The user’s shipping address. May be nil. If you’ve already collected a shipping address from your user, you may prefill it by setting a shippingAddress in PaymentContext’s prefilledInformation. When your user enters a new shipping address, PaymentContext will save it to the current customer object. When PaymentContext loads, if you haven’t manually set a prefilled value, any shipping information saved on the customer will be used to prefill the shipping address form. Note that because your customer’s email may not be the same as the email provided with their shipping info, PaymentContext will not prefill the shipping form’s email using your customer’s email.

    You should not rely on the shipping information stored on the Stripe customer for order fulfillment, as your user may change this information if they make multiple purchases. We recommend adding shipping information when you create a charge (which can also help prevent fraud), or saving it to your own database. https://stripe.com/docs/api/payment_intents/create#create_payment_intent-shipping

    Note: by default, your user will still be prompted to verify a prefilled shipping address. To change this behavior, you can set verifyPrefilledShippingAddress to NO in your STPPaymentConfiguration.

    Declaration

    Objective-C

    @property (readonly, nonatomic, nullable) STPAddress *shippingAddress;

    Swift

    var shippingAddress: STPAddress? { get }

  • The amount of money you’re requesting from the user, in the smallest currency unit for the selected currency. For example, to indicate $10 USD, use 1000 (i.e. 1000 cents). For more information, see https://stripe.com/docs/api/payment_intents/create#create_payment_intent-amount

    Note

    This value must be present and greater than zero in order for Apple Pay to be automatically enabled.

    Note

    You should only set either this or paymentSummaryItems, not both. The other will be automatically calculated on demand using your paymentCurrency.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic) NSInteger paymentAmount;

    Swift

    var paymentAmount: Int { get set }
    Show on GitHub

  • The three-letter currency code for the currency of the payment (i.e. USD, GBP, JPY, etc). Defaults to USD.

    Note

    Changing this property may change the return value of paymentAmount or paymentSummaryItems (whichever one you didn’t directly set yourself).

    Declaration

    Objective-C

    @property (readwrite, copy, nonatomic) NSString *_Nonnull paymentCurrency;

    Swift

    var paymentCurrency: String { get set }

  • If you support Apple Pay, you can optionally set the PKPaymentSummaryItems you want to display here instead of using paymentAmount. Note that the grand total (the amount of the last summary item) must be greater than zero. If not set, a single summary item will be automatically generated using paymentAmount and your configuration’s companyName.

    See

    PKPaymentRequest for more information

    Note

    You should only set either this or paymentAmount, not both. The other will be automatically calculated on demand using your paymentCurrency.

    Declaration

    Objective-C

    @property (readwrite, copy, nonatomic)
    NSArray<PKPaymentSummaryItem *> *_Nonnull paymentSummaryItems;

    Swift

    var paymentSummaryItems: [PKPaymentSummaryItem] { get set }

  • The presentation style used for all view controllers presented modally by the context. Since custom transition styles are not supported, you should set this to either UIModalPresentationFullScreen, UIModalPresentationPageSheet, or UIModalPresentationFormSheet. The default value is UIModalPresentationFullScreen.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic)
    UIModalPresentationStyle modalPresentationStyle;

    Swift

    var modalPresentationStyle: UIModalPresentationStyle { get set }
    Show on GitHub

  • The mode to use when displaying the title of the navigation bar in all view controllers presented by the context. The default value is automatic, which causes the title to use the same styling as the previously displayed navigation item (if the view controller is pushed onto the hostViewController).

    If the prefersLargeTitles property of the hostViewController‘s navigation bar is false, this property has no effect and the navigation item’s title is always displayed as a small title.

    If the view controller is presented modally, automatic and never always result in a navigation bar with a small title.

    Declaration

    Objective-C

    @property (assign, readwrite, nonatomic)
    UINavigationItemLargeTitleDisplayMode largeTitleDisplayMode;

  • A view that will be placed as the footer of the payment options selection view controller.

    When the footer view needs to be resized, it will be sent a sizeThatFits: call. The view should respond correctly to this method in order to be sized and positioned properly.

    Declaration

    Objective-C

    @property (readwrite, strong, nonatomic)
    UIView *_Nonnull paymentOptionsViewControllerFooterView;

    Swift

    var paymentOptionsViewControllerFooterView: UIView { get set }

  • If paymentContext:didFailToLoadWithError: is called on your delegate, you can in turn call this method to try loading again (if that hasn’t been called, calling this will do nothing). If retrying in turn fails, paymentContext:didFailToLoadWithError: will be called again (and you can again call this to keep retrying, etc).

    Declaration

    Objective-C

    - (void)retryLoading;

    Swift

    func retryLoading()

  • This creates, configures, and appropriately presents an STPPaymentOptionsViewController on top of the payment context’s hostViewController. It’ll be dismissed automatically when the user is done selecting their payment method.

    Note

    This method will do nothing if it is called while STPPaymentContext is already showing a view controller or in the middle of requesting a payment.

    Declaration

    Objective-C

  • Requests payment from the user. This may need to present some supplemental UI to the user, in which case it will be presented on the payment context’s hostViewController. For instance, if they’ve selected Apple Pay as their payment method, calling this method will show the payment sheet. If the user has a card on file, this will use that without presenting any additional UI. After this is called, the paymentContext:didCreatePaymentResult:completion: and paymentContext:didFinishWithStatus:error: methods will be called on the context’s delegate.

    Note

    This method will do nothing if it is called while STPPaymentContext is already showing a view controller, or in the middle of requesting a payment.
