只能选择一个联系人，如何使用ContactUI进行多选？

Question

希望：我正在尝试在ContactsUI中选择多个联系人：

CURRENT：我无法找到一种方法来获取表格视图单元格中的多个选择按钮

从下面的代码中我可以看到我正在使用contactPickerView所以我不知道我做错了什么：/

import UIKit
import ContactsUI
import Contacts


class FindContactsVC: UIViewController, CNContactPickerDelegate {

    //button to open contactUI
    @IBAction func contactsButton(_ sender: Any) {
        let cnPicker = CNContactPickerViewController()
        cnPicker.delegate = self    
        self.present(cnPicker, animated: true, completion: nil)  
    }

    //Works, but only allows me to select one at a time
    func contactPicker(_ picker: CNContactPickerViewController, didSelect contact: CNContact) {
        print(contact.phoneNumbers)
        print("WYASDFY")
    }

    //This function never runs :/
    func contactPicker(picker: CNContactPickerViewController, didSelectContacts contacts: [CNContact]){
       print(contacts)
        print("plz work!")
        contacts.forEach { contact in
            for number in contact.phoneNumbers {
                let phoneNumber = number.value 
                print("number is = \(phoneNumber)")
            }
        }
    }

    override func viewDidLoad() {
        super.viewDidLoad()       
    }
}

谢谢^。^

我还没有检查过代码的其他部分，但至少，你需要正确实现第二个委托方法：

func contactPicker(picker: CNContactPickerViewController, didSelectContacts contacts: [CNContact]){

↓

func contactPicker(_ picker: CNContactPickerViewController, didSelect contacts: [CNContact]) {
