What if there is more than one user input?
Following program will implement an alert that asks the user for username and password. Then log the credentials in the console.
@IBAction func alertCalled(_ sender: Any) {
let alert = UIAlertController(title: "Login", message: "Enter username and password", preferredStyle: .alert)
alert.addTextField() { textField in
textField.placeholder = "username"
}
alert.addTextField() { textField in
textField.placeholder = "password"
textField.isSecureTextEntry = true
}
let cancelAction = UIAlertAction(title: "Cancel", style: .cancel)
let yesAction = UIAlertAction(title: "OK", style: .destructive) { _ in
let usernameTF = alert.textFields![0] as UITextField
let passwordTF = alert.textFields![1] as UITextField
guard let username = usernameTF.text, let password = passwordTF.text else {
return
}
print("Username: \(username) || Password: \(password)")
}
alert.addAction(cancelAction)
alert.addAction(yesAction)
self.present(alert, animated: true)
}
