Question

This question is for Xcode 5 running iOS 7 and is super weird. I am trying to set all the UInavigation and UIBarButtonItem text colors to white.

So in my app launch

Answer 1

I had to do it this way in order for it to work on iOS 7

if ([MFMailComposeViewController canSendMail])
    {

        MFMailComposeViewController *mailViewController = [[MFMailComposeViewController alloc] init];
        mailViewController.mailComposeDelegate = self;

        [mailViewController.navigationBar setTintColor:[UIColor whiteColor]];
        [mailViewController.navigationBar setBarTintColor:[UIColor whiteColor]];
