```

## Discussion

Discussion Use this method to update shipping costs based on the shipping address selected by the user, as previously passed to the delegate in the PKPaymentAuthorizationViewControllerDelegate method. If no address has been selected, use the prepopulated address on the payment request. When this method is called, you create a new array of PKPaymentSummaryItem objects that represent the updated cost including shipping. For more information on creating summary items, see the PKPaymentRequest class’s paymentSummaryItems property.
