My iPad app must be runnable on iOS 4.3, and has to collect passwords. Because iOS 4 did not provide a password dialog, I have to provide my own.
The way I do this is to overlay my view with an image view that blocks access to the root view, and then put a password pseudo-dialog view on top of that. The pseudo dialog contains a prompt label, a secure text field, and two cancel/OK buttons. When the dialog view appears, I announce the prompt.
The problem is that VoiceOver doesn't understand that the buttons I'm blocking should no longer be available. Now that I think of it, that's reasonable.
When the password view appears, VoiceOver speaks the first word of my announcement, and then selects and speaks the bar button that reveals the master view. Other tap/swipe selections seem to be inactive, but if the user double-taps at the bar button selection, my app is in an unanticipated state.
What are my options? Do I have to disable (or turn off isAccessibilityElement) for all my interactive elements before showing my dialog?
