How to display iPhone Pass Code Screen, when user Touch-ID Authentication UserFallback?
问题 I want to handle UserFallback to show a pass code screen. I tried this tutorial, but when my UserFallback is called it will ask for Touch-ID again. If I use a wrong finger or Touch-ID did fail, then it's showing Apple's default Passcode screen. Please help me. 来源: https://stackoverflow.com/questions/31891577/how-to-display-iphone-pass-code-screen-when-user-touch-id-authentication-userfa
