我需要一个类似图像选择器的选项来选择联系人并显示电话号码，我已经设法使用以下代码来获取联系人姓名

通过使用此代码，它仅返回姓名，需要一个选项来从联系人列表中选择联系人

Answer 1

导入ContactsUI
并包含-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 2

import ContactsUI

private let contactPicker = CNContactPickerViewController()

启动联系人选择器的按钮单击：

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

实施委托方法

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) {

    }
}

您可以使用此扩展名获取联系人姓名。

extension CNContact {
    open func displayName() -> String {
        return givenName + " " + familyName
    }
}

这是获得一些详细信息的课程EPContact

Answer 4

快速5 和联系选择器获取电子邮件

我想展示一个示例，说明您可以如何执行您要求的相同操作，但是要发送电子邮件，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。它还具有“全部”选项的额外好处，如果用户选择，则将多封电子邮件连接为一个字符串。

首先请确保导入import ContactsUI

然后确保您有通往文本字段的出口。

@IBOutlet var emailTextField: UITextField!

接下来，您需要将联系人选择器设置为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，您可以使用以下代码将扩展名简单地添加到EmailViewController中：

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，要在按钮的动作事件中调用选择器，可以执行以下操作：

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

contactPicker.delegate = self之所以有效，是因为在我的案例中，viewController类（emailViewController）的扩展使它可以访问其所需的CNContactPickerDelegate协议功能。
