Autofill iOS12 alert message user to save password after login to the app first time?

问题

I'm implementing autoFill to my iOS app using this tutorial "iOS 12 Password Tools: Improving User Security and Experience" everything work fine but the iOS is not prompt me with UIAlert to save the password when I login for the first time. I want to ask how I can trigger the UIAlert to prompt the user to save the password to keychain first time?

回答1:

you have to clear the text fields and remove the view for View hierarchy.

Note: with Xcode 10 you can use save the username password in the simulator.

override func viewDidDisappear(_ animated: Bool) {
    super.viewDidDisappear(animated)
    view.endEditing(true)

    txtfEmail.text =  nil
    txtfPassword.text = nil
}
