Check instance of UIAlertView when going in background

Question

I have referred the following links for this issue, but neither of the solutions worked for me:

I think these solutions don't work for iOS7.

So now how would I be able to find out whether there is any UIAlertView open, when my application enters in background state. I want to dismiss the UIAlertView before going into the background.

Both Link are same. remove any 1 link – Toseef Khilji Dec 05 '13 at 12:07 — Toseef Khilji, Dec 05 '13 at 12:07
I have changed the 2nd link. – Kanan Vora Dec 05 '13 at 12:10 — Kanan Vora, Dec 05 '13 at 12:10

You get a notification when the app is send to background, so detect that notification in the class that displays the alert view and remove it, that's all

@KananVora You can register for UIApplicationDidEnterBackgroundNotification in the particular viewController you want to receive the notification. – dispatchMain Dec 05 '13 at 12:23

have you checked UIAlertView property @property(nonatomic, readonly, getter=isVisible) BOOL visible Also while going in the background you get a notification in - (void )applicationDidEnterBackground: you can check there and remove all alertviews if any

Remove alert in applicationDidEnterBackground

Add this line in your class

[[NSNotificationCenter defaultCenter] addObserver: self
                                         selector: @selector(enteredBackground:) 
                                            name:UIApplicationDidEnterBackgroundNotification
                                               object: nil];

And implement method as well

- (void)enteredBackground:(UIApplication *)application
    {
        if (mainAlertView && mainAlertView.isVisible) 
                 [mainAlertView dismissWithClickedButtonIndex:0 animated:NO];
    }
