ios - 从 iOS 中的联系方式获取街道、城市、州、 zip 和国家/地区并填充到标签

Question

我正在用 Xcode 8 和 swift 3 编写一个应用程序，我想在其中提取街道、城市、州、国家和邮政编码的邮政地址详细信息，并将它们填充到 View Controller 上的标签中。我已经修改了允许授权的 info.plist 文件，并在下面编写了以下代码。我创建了一个标签来保存信息以及一个按钮来访问联系人。

我能够获取填充到标签中的联系人的全名和电子邮件地址，但我无法弄清楚如何从邮政地址获取地址详细信息，例如街道地址、城市、州、邮政编码和国家/地区。我已经在 Stack Overflow 和互联网上用尽搜索无济于事。我恭敬地请求您的帮助。

任何见解和建议都将受到欢迎。

            contactStore.requestAccess(for: entityType, completionHandler:     {(success, nil) in
                if success {
                    self.openContacts()
                }
                else {
                    print("not authorized")
                }

    func openContacts() {
        let contactPicker = CNContactPickerViewController.init()
        contactPicker.delegate = self as CNContactPickerDelegate
        self.present(contactPicker, animated: true, completion: nil)
    }

    func contactPickerDidCancel(_picker: CNContactPickerViewController) {
        _picker.dismiss(animated: true) {

    func contactPicker(_ picker: CNContactPickerViewController, didSelect contact: CNContact) {
        // when a contact is selected get the full name
        let fullName = "\(contact.givenName) \(contact.familyName)"

        // the following gets the email address from contact
        var email = "No Email Address Found"
        if !contact.emailAddresses.isEmpty {
            let emailString = (((contact.emailAddresses[0] as AnyObject).value(forKey: "labelValuePair")
                as AnyObject).value(forKey: "value"))
            email = emailString! as! String
        }

        // start of adding postaladdresses
        var streetAddress = "No Postal Address Found"
        if !contact.postalAddresses.isEmpty {
            let streetAddressString = (((contact.postalAddresses[0] as AnyObject).value(forKey: "labelValuePair")
                as AnyObject).value(forKey: "value"))
            streetAddress = streetAddressString! as! String
        }

        // end of postal addresses

        // the following takes the information and populates a label on the view controller
        self.lblDetails.text = "\(fullName)\n\(email)\n\(streetAddress)"      //    \n\(streetName)
    }
}

你必须像这样使用:

if let addressString = (((contact.postalAddresses[0] as AnyObject).value(forKey: "labelValuePair") as AnyObject).value(forKey: "value")) as? CNPostalAddress {
    let mailAddress = CNPostalAddressFormatter.string(from:addressString, style: .mailingAddress)
    streetAddress = "\(addressString.street), \(addressString.city), \(addressString.state), \(addressString.postalCode), \(addressString.country)"
    streetAddress = "\(mailAddress)
}

您可以获得 address像这样 :

streetAddress = "\(addressString.street), \(addressString.city), \(addressString.state), \(addressString.postalCode), \(addressString.country)"

或者你可以得到 mailing address像这样:

let mailAddress = CNPostalAddressFormatter.string(from:addressString, style: .mailingAddress)
streetAddress = "\(mailAddress)
