ios - 查看<(空):0x0> does not conform to UITextInput protocol when tapping Return button on keyboard

Question

在键盘(真实设备)上点击返回时，控制台中会弹出此错误。一切都按原样执行。键盘隐藏，但此错误一直显示在控制台中。

import UIKit

class ViewController: UIViewController, UITextFieldDelegate {

       lazy var nameTextField: UITextField = {
         let textField = UITextField()
         textField.placeholder = "Name:"
         textField.delegate = self
         return textField
        }()
             
        lazy var surnameTextField: UITextField = {
          let textField = UITextField()
          textField.placeholder = "Surname:"
          textField.delegate = self
          return textField
         }()
       
         override func viewDidLoad() {
              super.viewDidLoad()
               
              view.addSubview(nameTextField)
              view.addSubview(surnameTextField)

         }

    func textFieldShouldReturn(_ textField: UITextField) -> Bool {
       view.endEditing(true)
       return true
    }


 }

如果你回来，你需要辞职 真 .

    public func textFieldShouldReturn(_ textField: UITextField) -> Bool {
        textField.resignFirstResponder()
        return true
    }
