Ios 嘿，伙计们，我'；I’我试图使用一个代码转到我的上一个屏幕，但是；X"；按钮是拒绝遵循的代码，如何解决？

//拒绝遵循代码的按钮的图像

是您在

NavigationController

堆栈中的

SignUpViewController

？您是如何呈现/推送它的？是的，视图控制器连接到了正确的文件。奇怪的是，我将尝试链接它again@BuğraCansınGöz，你是个天才！哈哈，我删除了以前的导航控制器，然后再次嵌入导航控制器，现在它正常工作了，谢谢你：）很高兴它工作了

import UIKit

class SignUpViewController: UIViewController {

    @IBOutlet weak var titleTextLabel: UILabel!
    @IBOutlet weak var avatar: UIImageView!
    @IBOutlet weak var fullnameContainterView: UIView!
    @IBOutlet weak var fullnameTextField: UITextField!
    @IBOutlet weak var emailContainterView: UIView!
    @IBOutlet weak var emailTextField: UITextField!
    @IBOutlet weak var passwordContainterView: UIView!
    @IBOutlet weak var passwordTextField: UITextField!
    @IBOutlet weak var signUpButton: UIButton!
    @IBOutlet weak var signInButton: UIButton!
    
    
    
    override func viewDidLoad() {
        super.viewDidLoad()
        setupUI()
    }
    
    func setupUI() {
        setupTitleLabel()
        setUpAvatar()
        setupFullNameTextField()
        setupEmailTextField()
        setupPasswordTextField()
        setupSignUpButton()
        setupSingnInButton()

    
    }

    @IBAction func dismissAction(_ sender: Any) {
        navigationController?.popViewController(animated: true)   //Code isn't working why? 
    }
    
}
