ios - Xcode Change View when app is in the backgorund -

-

i'm building app "locked" folder (locked view) inside of it, , wanted know how can change view when app in background. want every time user press home button, app return "asking password" view.

my problem dont know how segue view through didenterbackground method in appdelegate

thanks help!

you can not customize home button. when user presses home button inside app, go home screen (springboard). there no way change public apis. if somehow manage achieve goal, app not accepted itunes store. , don't know of private apis allow this. don't think possible on non-jailbroken device. may possible on jailbroken device if app has root powers.
