Change navigation bar color of CNContactPickerViewController iOS

Question

I've home view controller shown in image 1.

When user clicks on bar button another view controller is presented using presentViewController: method. This is CNContactPickerViewController which is completely native (shown in image 2).

How to change the color of UINavigationBar for this controller? I've tried below approach but didn't worked :

1. Changed navigation bar color in Appdelegate
2. Changed navigation bar color in global file that is inherited by controller.

I've used below code :

 [self.navigationBar setTranslucent:NO];

    [self.navigationBar setBackgroundImage:[UIImage imageNamed:@"NavigationBarBackground"]
                       forBarPosition:UIBarPositionAny barMetrics:UIBarMetricsDefault];

    [self.navigationBar setShadowImage:[UIImage new]];
    [self.navigationBar setTintColor:kBlackColor];
    [[UINavigationBar appearance] setTitleTextAttributes: [NSDictionary dictionaryWithObjectsAndKeys:
      [UIColor blackColor], NSForegroundColorAttributeName,nil]];

Also, when I run the app on device iPhone 6S iOS 9.3.2 the CNContactPickerViewController doesn't shows group button on navigation bar as shown in simulator.

Finally, I got it after doing lots of R&D. I've used below code for making Navigation Bar of CNContactPickerViewController red color.

    [[UINavigationBar appearance] setTranslucent:NO];
    [[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:213/255.0f green:38/255.0f blue:46/255.0f alpha:1.0]];
    [[UINavigationBar appearance] setTitleTextAttributes: [NSDictionary dictionaryWithObjectsAndKeys:
                                  [UIColor whiteColor], NSForegroundColorAttributeName,nil]];
    [[UINavigationBar appearance] setTintColor:kWhiteColor];
