How to set the navigation bar color when user taps "More"on UIActivityViewController?

Question

Whenever the user wants to select a new share method or action that isn't listed by default, by tapping the "More" button on the UIActivityViewController generated share sheet, a new view is displayed, something like this:

As you can see, the navigation bar itens are white, while it's background is a light grey. How can I change these colors to reflect my app UI?

I did this and it works for me:

Sublclass UIActivityViewController and override -(void)presentViewController:animated:completion:

- (void)presentViewController:(UIViewController *)viewControllerToPresent animated:(BOOL)flag completion:(void (^)(void))completion {
[viewControllerToPresent.view setTintColor:[[UINavigationBar appearance] tintColor]];
for (UIView *view in viewControllerToPresent.view.subviews) {
    if ([view isKindOfClass:[UINavigationBar class]]) {
        UINavigationBar *navigationBar = (UINavigationBar*)view;
        UIImage *navigationBarImage = [[UINavigationBar appearance] backgroundImageForBarPosition:UIBarPositionAny barMetrics:UIBarMetricsDefault];
        [navigationBar setBackgroundImage:navigationBarImage forBarPosition:UIBarPositionAny barMetrics:UIBarMetricsDefault];
        [navigationBar setTitleTextAttributes:[[UINavigationBar appearance] titleTextAttributes]];
    }
}

[super presentViewController:viewControllerToPresent animated:flag completion:^{
    [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
    if (completion) {
        completion();
    }
}];
}
