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.

WCAlertView is a subclass from UIAlertView with possibility of customization.
You can easly customize your UIAlertView.
There are a couple of predefined styles, you might use them instead of writing your own.
WCAlertView supports blocks.
You might set default appearance for all WCAlertView's:
[WCAlertView setDefaultStyle:WCAlertViewStyleWhite];Set default appearnce block for all WCAlertView's inside AppDelegate (similar to UIAppearance proxy)
[WCAlertView setDefaultCustomiaztonBlock:^(WCAlertView *alertView) {
alertView.labelTextColor = [UIColor colorWithRed:0.11f green:0.08f blue:0.39f alpha:1.00f];
alertView.labelShadowColor = [UIColor whiteColor];
UIColor *topGradient = [UIColor colorWithRed:1.0f green:1.0f blue:1.0f alpha:1.0f];
UIColor *middleGradient = [UIColor colorWithRed:0.93f green:0.94f blue:0.96f alpha:1.0f];
UIColor *bottomGradient = [UIColor colorWithRed:0.89f green:0.89f blue:0.92f alpha:1.00f];
alertView.gradientColors = @[topGradient,middleGradient,bottomGradient];
alertView.outerFrameColor = [UIColor colorWithRed:250.0f/255.0f green:250.0f/255.0f blue:250.0f/255.0f alpha:1.0f];
alertView.buttonTextColor = [UIColor colorWithRed:0.11f green:0.08f blue:0.39f alpha:1.00f];
alertView.buttonShadowColor = [UIColor whiteColor];
