禁用 iOS11 更新密码 ActionSheet

Question

Is there a way to disable the iOS11's "Update Password" ActionSheet (Part of iOS11's password autofill feature https://developer.apple.com/documentation/security/password_autofill/ ) which is presented after the user logs in and I navigate to a new ViewController. Because sometimes it's presented even though the login operation was not successful.

I want to indicate to the OS that the login was not successful and therefore the password existing in the Keychain should not be replaced with the new one.

Answer 1

You can set nil to your text field, such that the AutoFill UI will not update password because there is no appropriate account to update.

With a little delay, you set the original text back to the text field.
