Parent window, UIAlertViews, UIActionSheets and the keyboard

[rolandleth]

The issue (#16) started with a positioning problem, which is now fixed, but it revealed another kinda hard to fix problem - displaying the lockscreen when an alertView / actionSheet is visible, or displaying one after the lockscreen is visible results in a few cases:

• the lockscreen and the keyboard appear on top the av/as, but
  • the dimming of the av/as appears on top the lockscreen;
  • if the app is closed and reopened, the order becomes av/as - lockscreen - dimming - keyboard.
• the lockscreen always appears behind the av/as, while the keyboard
  • doesn't appear until the av/as is dismissed;
  • appears on top on the av/as - if the app is closed and reopened with the av/as visible.
• the lockscreen appears above the av/as, while the keyboard appears below, so there's no way to enter the passcode.

The current implementation shows the lockscreen behind the av/as.

Any help would be greatly appreciated.
