How to toggle a UITextField secure text entry (hide password) in Swift?

Question

I currently have a UITextfield with an eye icon in it that when pressed is supposed to toggle the secure text entry on and off.

I know you can che

Answer 1

As others have noted, the property is secureTextEntry, but you won't find this in the UITextField documentation, as it is actually inherited by a UITextField through the UITextInputTraits protocol- https://developer.apple.com/library/ios/documentation/UIKit/Reference/UITextInputTraits_Protocol/#//apple_ref/occ/intfp/UITextInputTraits/secureTextEntry

You can simply toggle this value each time your button is tapped:

@IBAction func togglePasswordSecurity(sender: UIButton) {
    self.passwordField.secureTextEntry = !self.passwordField.secureTextEntry
}

Answer 2

For Xamarin folks:

passwordField.SecureTextEntry = passwordField.SecureTextEntry ? passwordField.SecureTextEntry = false : passwordField.SecureTextEntry = true;

Answer 3

try this line:

@IBAction func btnClick(sender: AnyObject) {
    let btn : UIButton = sender as! UIButton
    if btn.tag == 0{
        btn.tag = 1
        textFieldSecure.secureTextEntry = NO
    }
    else{
        btn.tag = 0
        textFieldSecure.secureTextEntry = NO;
    }
}

In Swift 4

 var iconClick : Bool!

    override func viewDidLoad() {
        super.viewDidLoad()
        iconClick = true
     }


    @IBAction func showHideAction(_ sender: Any)
    {
        let userPassword = userPasswordTextFiled.text!;

        if(iconClick == true) {
            userPasswordTextFiled.isSecureTextEntry = false
            iconClick = false
        } else {
            userPasswordTextFiled.isSecureTextEntry = true
            iconClick = true
        }

}

Answer 6

Try this code in swift 4, tried to make a reusable code within a controller. I have set different image for buttons in storyboard as shown in the link https://stackoverflow.com/a/47669422/8334818

@IBAction func clickedShowPassword(_ sender: UIButton) {
        var textField :UITextField? = nil
        print("btn ",sender.isSelected.description)
        switch sender {
        case encryptOldPswdBtn:
            encryptOldPswdBtn.isSelected = !encryptOldPswdBtn.isSelected
            textField = oldPasswordTextField

        default:
          break
        }

        print("text ",textField?.isSecureTextEntry.description)
        textField?.isSecureTextEntry = !(textField?.isSecureTextEntry ?? false)

    }
