只能选择一个联系人，如何使用ContactUI实现多选？

Question

期望：我试图能够在 ContactsUI 中选择多个联系人，如下所示：

当前：我找不到在表视图单元格中获取多重选择按钮的方法

正如您从下面的代码中看到的，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^.^

我没有检查代码的其他部分，但至少，您需要正确实现第二个委托方法：

\n\n

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

\n\n

\xe2\x86\x93

\n\n

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

\n
