objective c - Find UIAlertView without having reference to it iOS 7

Question

I was using a code snippet in my project answered here: UIAlertView without having reference to it

Here's the code:

+ (UIAlertView *) getUIAlertViewIfShown {
    if ([[[UIApplication sharedApplication] windows] count] == 1) {
        return nil;
    }

    UIWindow *window = [[[UIApplication sharedApplication] windows] objectAtIndex:1];
    if ([window.subviews count] > 0) {
        UIView *view = [window.subviews objectAtIndex:0];
        if ([view isKindOfClass:[UIAlertView class]]) {
            return (UIAlertView *) view;
        }
    }
    return nil;
}

Unfortunately its not working in iOS 7 and I'm unable to dismiss an alert view. While debugging I found that in the loop its showing that view is of class UITransitionView. Pretty confusing because I couldn't find any quick documentation for this view class.

Any ideas how can I fix this problem?

In iOS7, the UIAlertView window does not appear in -[UIApplication windows]. In fact, the UIAlertView itself is never added to any window, -[UIAlertView window] is always nil. Instead, the alert view manages a variety of undocumented views placed in -[UIApplication keyWindow] with no reference back to the alert view.

Your only real option in iOS7 is to actually keep track of your alert views.
