Question

您正在尝试通过在文本字段中输入特定单词来执行segue。到目前为止，我的教练技巧让我想到了这一点。我没有收到错误，模拟器崩溃了。

任何提示？

导入UIKit

类CodewordVC：UIViewController，UITextFieldDelegate { @IBOutlet weak var passWordInput：UITextField！

override func viewDidLoad() {
    super.viewDidLoad()

passWordInput.delegate = self }

@IBAction func LosButton(_ sender: UIButton) {
    //passwords
     let realPassword1 = "rudi"

    if passWordInput.text == realPassword1 {
 self .performSegue(withIdentifier: "rudi", sender: self)
}

func dismissButton(_ sender: UIButton) {
    dismiss(animated: true, completion: nil)

Answer 1

搞定了！无法解释，但那就是答案：

import UIKit

class CodewordVC: UIViewController,  UITextFieldDelegate {

    @IBOutlet weak var passWordInput: UITextField!

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

    let realPassword1 = "rudi"

    @IBAction func LosButton(_ sender: UIButton) {

        passWordInput.delegate = self
        //passwords

        if self.passWordInput.text == realPassword1 {

            DispatchQueue.main.async(){

                self.performSegue(withIdentifier: "rudi", sender: self)

            }
        }
    }

    func dismissButton(_ sender: UIButton) {
        dismiss(animated: true, completion: nil)
    }
}

Swift 3触发segue会导致崩溃
