import ContactsUI

private let contactPicker = CNContactPickerViewController()

Button click that initiates contact picker:

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)
}

Implement delegate methods

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) {

    }
}

You can use this extension to get a contact name.

您可以使用此扩展程序获取联系人姓名。

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

This is Class to get Some details EPContact

这是获取一些详细信息的类EPContact

Swift 5& Contact Picker Get Email

Swift 5和联系人选择器获取电子邮件

I wanted to show an example of how you can do the same thing you asked for but for email instead and updated for Swift 5 since some of the answers do not compile correctly above. This also has the added bonus of the 'all' option which will concatenate multiple emails into one string if the user selects it or not.

我想展示一个示例，说明如何执行您要求的相同操作，但使用电子邮件代替并针对 Swift 5 进行更新，因为上面的某些答案编译不正确。这也有“全部”选项的额外好处，如果用户选择它，它将把多封电子邮件连接成一个字符串。

First make sure to import import ContactsUI

首先确保导入 import ContactsUI

Then make sure you have an outlet to your textfield.

然后确保您的文本字段有一个出口。

@IBOutlet var emailTextField: UITextField!

Next you need to set the contact picker as a member variable of your viewController. This will hold the information for showing the contact picker later.

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...
}

Finally you can simply add this extension to the EmailViewController with the code below:

最后，您可以使用以下代码将此扩展程序添加到 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")
    }
}

To call up the picker in the action event of a button for example you could do this:

例如，要在按钮的操作事件中调用选择器，您可以执行以下操作：

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

contactPicker.delegate = selfworks because of the extension on the viewController class (emailViewController) in my case that gives it access to the CNContactPickerDelegateprotocol functions it requires.

contactPicker.delegate = self在我的情况下，由于 viewController 类（emailViewController）的扩展，它可以访问CNContactPickerDelegate它所需的协议功能。
