进口ContactsUI
并包括 - CNContactPickerDelegate

import ContactsUI

class YourViewController: CNContactPickerDelegate{

    //MARK:- contact picker
    func onClickPickContact(){


        let contactPicker = CNContactPickerViewController()
        contactPicker.delegate = self
        contactPicker.displayedPropertyKeys =
            [CNContactGivenNameKey
                , CNContactPhoneNumbersKey]
        self.present(contactPicker, animated: true, completion: nil)

    }

    func contactPicker(_ picker: CNContactPickerViewController,
                       didSelect contactProperty: CNContactProperty) {

    }

    func contactPicker(_ picker: CNContactPickerViewController, didSelect contact: CNContact) {
        // You can fetch selected name and number in the following way

        // user name
        let userName:String = contact.givenName

        // user phone number
        let userPhoneNumbers:[CNLabeledValue<CNPhoneNumber>] = contact.phoneNumbers
        let firstPhoneNumber:CNPhoneNumber = userPhoneNumbers[0].value


        // user phone number string
        let primaryPhoneNumberStr:String = firstPhoneNumber.stringValue

        print(primaryPhoneNumberStr)

    }

    func contactPickerDidCancel(_ picker: CNContactPickerViewController) {

    }
}

Answer 3

import ContactsUI

private let contactPicker = CNContactPickerViewController()

启动联系人选择器的按钮点击：

@IBAction func accessContacts(_ sender: Any) {
    contactPicker.delegate = self
    self.present(contactPicker, animated: true, completion: nil)
}

实现委托方法

extension YourViewController: CNContactPickerDelegate {

    func contactPicker(_ picker: CNContactPickerViewController, didSelect contact: CNContact) {
        let phoneNumberCount = contact.phoneNumbers.count

        guard phoneNumberCount > 0 else {
            dismiss(animated: true)
            //show pop up: "Selected contact does not have a number"
            return
        }

        if phoneNumberCount == 1 {
            setNumberFromContact(contactNumber: contact.phoneNumbers[0].value.stringValue)

        } else {
            let alertController = UIAlertController(title: "Select one of the numbers", message: nil, preferredStyle: .alert)

            for i in 0...phoneNumberCount-1 {
                let phoneAction = UIAlertAction(title: contact.phoneNumbers[i].value.stringValue, style: .default, handler: {
                alert -> Void in
                    self.setNumberFromContact(contactNumber: contact.phoneNumbers[i].value.stringValue)
                })
                alertController.addAction(phoneAction)
            }
            let cancelAction = UIAlertAction(title: "Cancel", style: .destructive, handler: {
            alert -> Void in

            })
            alertController.addAction(cancelAction)

            dismiss(animated: true)
            self.present(alertController, animated: true, completion: nil)
        }
    }

    func setNumberFromContact(contactNumber: String) {

        //UPDATE YOUR NUMBER SELECTION LOGIC AND PERFORM ACTION WITH THE SELECTED NUMBER

        var contactNumber = contactNumber.replacingOccurrences(of: "-", with: "")
        contactNumber = contactNumber.replacingOccurrences(of: "(", with: "")
        contactNumber = contactNumber.replacingOccurrences(of: ")", with: "")
        contactNumber = contactNumber.removeWhitespacesInBetween()
        guard contactNumber.count >= 10 else {
            dismiss(animated: true) {
                self.popUpMessageError(value: 10, message: "Selected contact does not have a valid number")
            }
            return
        }
        textFieldNumber.text = String(contactNumber.suffix(10))

    }

    func contactPickerDidCancel(_ picker: CNContactPickerViewController) {

    }
}

Swift 5 & 联系人选择器获取电子邮件

我想展示一个示例，说明如何执行与您要求相同的操作，但使用电子邮件代替，并针对 Swift 5 进行了更新，因为上面的某些答案无法正确编译。这还有 'all' 选项的额外好处，如果用户选择或不选择，它将把多封电子邮件连接成一个字符串。

首先确保导入import ContactsUI

然后确保您的文本字段有插座。

@IBOutlet var emailTextField: UITextField!

接下来您需要将联系人选择器设置为您的 viewController 的成员变量。这将保存稍后显示联系人选择器的信息。

class EmailViewController: UIViewController {
    @IBOutlet var emailTextField: UITextField!
    private let contactPicker = CNContactPickerViewController()

    //... rest of view controller code, etc...
}

最后，您只需使用以下代码将此扩展添加到 EmailViewController：

extension EmailViewController: CNContactPickerDelegate {

    func contactPicker(_ picker: CNContactPickerViewController, didSelect contact: CNContact) {
        let emailNumberCount = contact.emailAddresses.count

        //@JA - They have to have at least 1 email address
        guard emailNumberCount > 0 else {
            dismiss(animated: true)
            //show pop up: "Selected contact does not have a number"
            let alertController = UIAlertController(title: "No emails found for contact: "+contact.givenName+" "+contact.familyName, message: nil, preferredStyle: .alert)
            let cancelAction = UIAlertAction(title: "Ok", style: .default, handler: {
            alert -> Void in

            })
            alertController.addAction(cancelAction)
            self.present(alertController, animated: true, completion: nil)
            return
        }

        //@JA - If they have only 1 email it's easy.  If there is many emails we want to concatenate them and separate by commas , , ...
        if emailNumberCount == 1 {
            setEmailFromContact(contactEmail: contact.emailAddresses[0].value as String)
        } else {
            let alertController = UIAlertController(title: "Select an email from contact: "+contact.givenName+" "+contact.familyName+" or select 'All' to send to every email listed.", message: nil, preferredStyle: .alert)

            for i in 0...emailNumberCount-1 {
                let emailAction = UIAlertAction(title: contact.emailAddresses[i].value as String, style: .default, handler: {
                alert -> Void in
                    self.setEmailFromContact(contactEmail: contact.emailAddresses[i].value as String)
                })
                alertController.addAction(emailAction)
            }

            let allAction = UIAlertAction(title: "All", style: .destructive, handler: {
            alert -> Void in
                var emailConcat = ""
                for i in 0...emailNumberCount-1{
                    if(i != emailNumberCount-1){ //@JA - Only add the , if we are not on the last item of the array
                        emailConcat = emailConcat + (contact.emailAddresses[i].value as String)+","
                    }else{
                        emailConcat = emailConcat + (contact.emailAddresses[i].value as String)
                    }
                }
                self.setEmailFromContact(contactEmail: emailConcat)//@JA - Sends the concatenated version of the emails separated by commas
            })
            alertController.addAction(allAction)

            let cancelAction = UIAlertAction(title: "Cancel", style: .cancel, handler: {
            alert -> Void in

            })
            alertController.addAction(cancelAction)

            dismiss(animated: true)
            self.present(alertController, animated: true, completion: nil)
        }
    }

    func setEmailFromContact(contactEmail: String){
        emailTextField.text = contactEmail
    }

    func contactPickerDidCancel(_ picker: CNContactPickerViewController) {
        print("contact picker canceled")
    }
}

例如，要在按钮的操作事件中调用选择器，您可以这样做：

@IBAction func contactsButtonPressed(_ sender: UIButton) {
     contactPicker.delegate = self
     self.present(contactPicker, animated: true, completion: nil)
}

contactPicker.delegate = self 工作是因为 viewController class (emailViewController) 上的扩展，在我的例子中，它可以访问它需要的 CNContactPickerDelegate 协议功能。

Answer 5

如果联系人有多个phone号码，那么您可以通过比较'contactProperty.identifier'得到所选号码如下-

  public func contactPicker(_ picker: CNContactPickerViewController, didSelect contactProperty: CNContactProperty) {
      tvName.text = contactProperty.contact.givenName

      var selectedNo = ""
      if contactProperty.key == "phoneNumbers" {
          contactProperty.contact.phoneNumbers.forEach({ phone in
              if phone.identifier == contactProperty.identifier {
                  selectedNo = phone.value.stringValue
              }
          })
      }
      tvContact.text = selectedNo
  }
