我能够从 Apple Pay 成功检索所有数据，包括加密的支付数据、名字、姓氏和账单地址。但是，我似乎无法弄清楚如何从 Apple Pay 结帐期间显示的“联系人”部分中检索 电话号码 和 电子邮件地址。我需要检索这些值，以便将它们提交给我的下游支付提供商。请帮忙：

extension ViewController: PKPaymentAuthorizationViewControllerDelegate {

    /* USER HAS AUTHORIZED PAYMENT */
    func paymentAuthorizationViewController(controller: PKPaymentAuthorizationViewController!, didAuthorizePayment payment: PKPayment!, completion: ((PKPaymentAuthorizationStatus) -> Void)!) {

        //Declare a dictionary of request parameters
        var parameters = Dictionary<String, String>()

        //Get Encrypted Payment Data from AP
        parameters["encryptedPayment_data"] = payment.token.paymentData.base64EncodedStringWithOptions(nil)

        let billingAddress: ABRecord = payment.billingAddress

        parameters["billTo_firstName"] = ABRecordCopyValue(billingAddress, kABPersonFirstNameProperty).takeRetainedValue() as? String
        parameters["billTo_lastName"] = ABRecordCopyValue(billingAddress, kABPersonLastNameProperty).takeRetainedValue() as? String

        //Extract billing address from ABRecord format and assign accordingly
        let addressProperty: ABMultiValueRef = ABRecordCopyValue(billingAddress, kABPersonAddressProperty).takeUnretainedValue() as ABMultiValueRef

        if let dict: NSDictionary = ABMultiValueCopyValueAtIndex(addressProperty, 0).takeUnretainedValue() as? NSDictionary {
            parameters["billTo_street1"] = dict[String(kABPersonAddressStreetKey)] as? String
            parameters["billTo_city"] = dict[String(kABPersonAddressCityKey)] as? String
            parameters["billTo_state"] = dict[String(kABPersonAddressStateKey)] as? String
            parameters["billTo_postalCode"] = dict[String(kABPersonAddressZIPKey)] as? String
            parameters["billTo_country"] = dict[String(kABPersonAddressCountryKey)] as? String //"United States"
        }

        //Can't figure out how to obtain these from Apple Pay!
        parameters["billTo_email"] = "null@sample.com"
        parameters["billTo_phoneNumber"] = "5555555555"

你可以试试

let emails: ABMultiValueRef = ABRecordCopyValue(billingAddress, kABPersonEmailProperty).takeRetainedValue() as ABMultiValueRef
  if ABMultiValueGetCount(emails) > 0 {
    let email = ABMultiValueCopyValueAtIndex(emails, 0).takeRetainedValue() as String
    NSLog(email)  
  }

感谢您的回复，然而，第一行代码导致“致命错误：在展开可选值 (lldb) 时意外发现 nil”。我将此解释为意味着 kABPersonEmailProperty 在从 Apple Pay 返回的 payment.billingAddress 中为零。电子邮件和电话还有可能暴露在哪里？
忘了提及我正在将帐单和送货地址设置为必需，并且它们确实出现在 AP 结帐过程中：request.requiredBillingAddressFields = PKAddressField.All;request.requiredShippingAddressFields = PKAddressField.All;
情节变厚了...我可以使用您的代码从 payment.shippingAddress 获取电子邮件，但 payment.billingAddress 返回 nil。我想知道 Apple 是否故意阻止这一点？
Apple Pay 支付单只有一处输入邮箱和电话信息，返回的是shippingAddress，而不是billingAddress。
任何人都可以把它转换成Objective C吗？
