iOS 10 can no longer set barcolor and tint on MFMessageComposeViewController

Question

Below code works on iOS version 9.x or less, for some reason this does not work if iOS 10

 if([MFMessageComposeViewController canSendText])
             {

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...
    }];
}
