title: iOS 12.0 : Is there a way to set MFMailComposeViewController navigation bar title's text to white?
body: <p>Currently, I haven't found a way to do this for iOS 12.0. I've tried setting bar tint like so. </p>
  
  <pre><code>[mailController.navigationBar setTintColor:[UIColor whiteColor]];
  </code></pre>
  
  <p>Then, I tried setting the title text attribute with the following code</p>
  
  <pre><code>   [mailController.navigationController.navigationBar setTitleTextAttributes:
   @{NSForegroundColorAttributeName:[UIColor WhiteColor]};
  </code></pre>
  
  <p>I've tried more options that I found on StackOverflow, but none of them worked. I am hoping that someone found a reliable way to change the navigation bar title text color.  It stays black no matter what I do. The bar button's colors change correctly, but not the navigation bar title. </p>
