Ios Can'；无法从ApplePay PKPaymentAuthorizationViewController获取电子邮件

我正在使用ApplePay，需要电子邮件作为联系信息。当我试图收到电子邮件时，我收到的电子邮件结果是“发送”，我甚至不知道它来自哪里

我要求在请求中填写电子邮件字段，并填写电子邮件信息

request.requiredShippingAddressFields = PKAddressField.PostalAddress | PKAddressField.Email

代码如下：

func paymentAuthorizationViewController(controller: PKPaymentAuthorizationViewController!, didAuthorizePayment payment: PKPayment!, completion: ((PKPaymentAuthorizationStatus) -> Void)!) {

    let address: ABRecord! = payment.shippingAddress

    let emails: ABMultiValueRef = ABRecordCopyValue(address, kABPersonEmailProperty).takeRetainedValue() as ABMultiValueRef
    if ABMultiValueGetCount(emails) > 0 {
        let email = ABMultiValueCopyLabelAtIndex(emails, 0).takeRetainedValue()
        NSLog(email)  //Here prints "Shipping"
     }
    ...
 }

这是收电子邮件的好地方吗？如果不是，正确的方法是什么

尝试获取电话号码（KabbersonPhoneProperty），结果也会打印为“Shipping”。

您的代码中有一个微妙的“输入错误：）

ab多值CopyLabelaIndex

复制条目的标签（即“装运”）。您需要使用

ABMultiValueCopyValueAtIndex

获取该值

  let emails: ABMultiValueRef = ABRecordCopyValue(address, kABPersonEmailProperty).takeRetainedValue() as ABMultiValueRef
  if ABMultiValueGetCount(emails) > 0 {
    let email = ABMultiValueCopyValueAtIndex(emails, 0).takeRetainedValue() as String
    NSLog(email)  //Here prints your email address!
  }
