iPhone, How to show alter dialog on Lock Screen?
I see some apps like 'Lock Calendar' that include this feature, and I know that we can maybe use keyWindows to trace the view and replace the wallpaper etc., but I feel that if the app makes use of this it will probably be refused by Apple ...
or maybe the sdk has provide other API for this purpose?
any tip will be appreciate ...
"Lock Calender" is for jailbroken phones and it would definitely not be approved by Apple. There's no sanctioned way to do what it sounds like you'd want to do.
I'm pretty sure this will only work on a jail-broken phone. If you want to submit an app with this functionality to the app store, you're out of luck.
