Issue

• For some reasons in iOS10.x barTintColor is not working on some of the sharing containers.
• But there's a workaround to fix the Navigation bar colour on all the sharing containers.

Solution

• Use UINavigationBar.appearance() to change the navigation bar colour.
• Use backgroundColor property & setBackgroundImage(_:for:) method to fix the navigation bar colour.

Code

/// Method to set navigation bar color
func setNavigationBar() -> Void
{
    // barTintColor will apply color for the app's navigation bar
    UINavigationBar.appearance().barTintColor       = UIColor.blue

    // backgroundColor will apply color for some of the sharing container's app except for Messages app
    UINavigationBar.appearance().backgroundColor    = UIColor.blue

    // backgroundImage will apply the color image for navigation bar for most of the sharing container's except for `Notes`
    UINavigationBar.appearance().setBackgroundImage(UIImage(color: UIColor.blue), for:UIBarMetrics.default)
}

/// UIImage extension to create an image from specified color
extension UIImage
{
    public convenience init?(color: UIColor, size: CGSize = CGSize(width: 1, height: 1)) {
        let rect = CGRect(origin: .zero, size: size)
        UIGraphicsBeginImageContextWithOptions(rect.size, false, 0.0)
        color.setFill()
        UIRectFill(rect)
        let image = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()

        guard let cgImage = image?.cgImage else { return nil }
        self.init(cgImage: cgImage)
    }
}

Hope it helps!.

This works for me at least for title and button items.

[UIBarButtonItem appearanceWhenContainedIn:[UINavigationBar class], nil].tintColor = [UIColor redColor];
[UINavigationBar appearance].titleTextAttributes = @{NSForegroundColorAttributeName: [UIColor redColor]};

Look for more info here: https://developer.apple.com/reference/uikit/uiappearance

Hope this helps. Cheers

Prior to iOS 10, I was using the appearance proxy for UINavigationBar, something like this:

NSDictionary* titleAttribs = @{ NSForegroundColorAttributeName: [ColoursAndStyles sharedInstance].fontColourNavBarTitle,
                                NSFontAttributeName: [ColoursAndStyles sharedInstance].fontNavbarBoldTitle };

[[UINavigationBar appearance] setBarTintColor:[ColoursAndStyles sharedInstance].viewColourNavBarMain];
[[UINavigationBar appearance] setTintColor:[ColoursAndStyles sharedInstance].viewColourNavBarTint];
[[UINavigationBar appearance] setTitleTextAttributes:titleAttribs];

This covered my use of MFMessageComposeViewController, with setTitleTextAttributes taking care of the text colour of the title/caption.

With iOS 10, I'm using the following work around. Just before I present the MFMessageComposeViewController, I change the title text attributes. E.g.:

- (void)sendTap:(id)s
{
    // some code...

    NSDictionary* newTitleAttribs = @{ NSForegroundColorAttributeName: [ColoursAndStyles sharedInstance].fontColourTitleStrip,
                                       NSFontAttributeName: [ColoursAndStyles sharedInstance].fontNavbarBoldTitle };

    [[UINavigationBar appearance] setTitleTextAttributes:newTitleAttribs];

    // present the MFMessageComposeViewController...
}

And then set things back to how I want them for the rest of the app, when the MFMessageComposeViewController finishes, e.g.:

- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
    NSDictionary* titleAttribs = @{ NSForegroundColorAttributeName: [ColoursAndStyles sharedInstance].fontColourNavBarTitle,
                                    NSFontAttributeName: [ColoursAndStyles sharedInstance].fontNavbarBoldTitle };

    [[UINavigationBar appearance] setTitleTextAttributes:titleAttribs];

    // some code...

    [controller dismissViewControllerAnimated:YES completion:^{
        // some code...
    }];
}

Objective-C solution:

[[UINavigationBar appearance] setBackgroundImage:[UIImage imageWithColor:[UIColor redColor]] forBarMetrics:UIBarMetricsDefault];
[[UINavigationBar appearance] setTranslucent:NO];
[[UINavigationBar appearance] setBarTintColor:[UIColor redColor]];
[[UINavigationBar appearance] setTintColor:[UIColor redColor]];

Image with color method:

+ (UIImage *)imageWithColor:(UIColor *)paramColor
{
    CGRect frame = CGRectMake(0.0f, 0.0f, 1.0f, 1.0f);
    UIGraphicsBeginImageContextWithOptions(frame.size, NO, [UIScreen mainScreen].scale);
    CGContextRef context = UIGraphicsGetCurrentContext();
    CGContextSetInterpolationQuality(context, kCGInterpolationHigh);

    CGContextSetFillColorWithColor(context, [paramColor CGColor]);
    CGContextFillRect(context, frame);

    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return image;
}
