Is there a notification on iOS if a UIAlertView is shown?
Wondering if there is a notification available if a UIAlertView
pops up?
Background: my app asks the user for a PIN after a period of inactivity but I would like to prevent it if an alert is on screen.
I don't want to go开发者_JAVA技巧 through my code and find all alerts and disable the PIN checker, instead a notification would be awesome. Any hope with NSNotification
?
Just found the answer. It is hidden in here:
Can I get message when I show UIAlertView
If you listen to the "UIWindowDidBecomeVisibleNotification
" notification, it will also fire for your own alerts, not only for system alerts.
For your own alerts, the application does not resign activiation however.
