STPPaymentCardTextField

@interface STPPaymentCardTextField : UIControl <UIKeyInput>

STPPaymentCardTextField is a text field with similar properties to UITextField, but specialized for collecting credit/debit card information. It manages multiple UITextFields under the hood to collect this information. It’s designed to fit on a single line, and from a design perspective can be used anywhere a UITextField would be appropriate.

  • Controls if a postal code entry field can be displayed to the user.

    Default is YES.

    If YES, the type of code entry shown is controlled by the set countryCode value. Some country codes may result in no postal code entry being shown if those countries do not commonly use postal codes.

    If NO, no postal code entry will ever be displayed.

  • Convenience property for creating an STPPaymentMethodCardParams from the currently entered information or programmatically setting the field’s contents. For example, if you’re using another library to scan your user’s credit card with a camera, you can assemble that data into an STPPaymentMethodCardParams object and set this property to that object to prefill the fields you’ve collected.

    Accessing this property returns a copied cardParams. The only way to change properties in this object is to make changes to a STPPaymentMethodCardParams you own (retrieved from this text field if desired), and then set this property to the new value.

    Declaration

    Objective-C

    @property (copy, nonatomic, nonnull) STPPaymentMethodCardParams *cardParams;

    Swift

    @NSCopying var cardParams: STPPaymentMethodCardParams { get set }
