iOS 11.0 UITextField secureTextEntry不起作用？

Question

我发现secureTextEntry在iOS 11.0上不起作用，我的代码很简单：

tfPwd1.keyboardType = UIKeyboardTypeNumberPad;
tfPwd1.secureTextEntry = YES;
tfPwd1.delegate = self;

我该怎么做才能解决这个问题？

Answer 1

将.secureTextEntry更改为.isSecureTextEntry

希望它有效。

Answer 2

我只是检查我的系统使用此代码

 override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        txtfld.isSecureTextEntry = true
    }

Answer 3

你在任何地方打电话给[tfPwd1 becomeFirstResponder]吗？在致电tfPwd1.secureTextEntry = YES;之前添加[tfPwd1 becomeFirstResponder]。在UIKeyboard出现时不要添加
