I want to change color of icons (and probably badge) in `moreNavigationController` from gray to something else.

I've read and successfully changed color of background and text. I did this by "replacing" data source of `moreViewController` (described e.g. here [Customizing the More menu on a Tab bar](https://stackoverflow.com/questions/438381/customizing-the-more-menu-on-a-tab-bar) ). But updating icons (also textLabel value) here makes no effect. Is it possible to change this gray color to white (or anything else)? Or I have to implement my own `tabBarController`? (any good tutorials?)

PS. I know how to change icons on tab bar itself, the question is how to do this in `moreViewController`?

Thanks!
