Changing MFMailComposeViewControllers status bar style

Question

I can't get the status bar to display the clock battery etc in white. I read a lot of similar questions on stack overflow but most are old and not written in swift. The most recent answers I could find suggested to override func preferredStatusBarStyle which is no longer a function. I tried the following, but it doesn't work.

import Foundation
import UIKit
import MessageUI

class ContactUsViewController: MFMailComposeViewController {
    
    override var preferredStatusBarStyle: UIStatusBarStyle {
        return .lightContent
    }
    
    override func loadView() {
        super.loadView()
    }
    
    override func viewDidLoad() {
        print("mail viewDidLoad()")
        self.setNeedsStatusBarAppearanceUpdate()
    }
    
}

I call the view controller using.

if !MFMailComposeViewController.canSendMail() {
    print("Mail services are not available")
    return
}
self.timeSlider.removeFromSuperview()
let contactVC = ContactUsViewController()// MFMailComposeViewController()
contactVC.navigationBar.tintColor = UIColor.white
contactVC.mailComposeDelegate = self
            
// Configure the fields of the interface.
contactVC.setToRecipients(["support@example.com"])
contactVC.setSubject("Your subject here")
contactVC.setMessageBody("Enter message about bugs, problems, ideas how to make the app better etc.", isHTML: false)
contactVC.modalPresentationCapturesStatusBarAppearance = true
// Present the view controller
self.navigationController?.present(contactVC, animated: true, completion: nil)

What is missing from the view controller to change its StatusBarStyle?

Swift 2 - UIApplication.sharedApplication().statusBarStyle = .LightContent Swift 3 - UIApplication.shared.statusBarStyle = .lightContent — Sagar Snehi, Jul 10 '17 at 09:35
did you add this "View controller-based status bar appearance" to the app info list — zombie, Jul 10 '17 at 09:39
@SagarSnehi I'm not quite sure what you mean with your comment. I already do set `UIApplication.shared.statusBarStyle = UIStatusBarStyle.lightContent` inside my `AppDelegate` — Lukasz, Jul 10 '17 at 09:47

First in the app info list add the key "View controller-based status bar appearance" with the value of NO

then check this code

func showContactUs() {
   if !MFMailComposeViewController.canSendMail() {
      print("Mail services are not available")
      return
   }
   let contactVC = ContactUsViewController()

   //To make the nav bar stand out
   //contactVC.navigationBar.barStyle = .blackTranslucent

   contactVC.setToRecipients(["support@example.com"])
   contactVC.setSubject("Your subject here")
   contactVC.setMessageBody("Enter message about bugs, problems, ideas how to make the app better etc.", isHTML: false)
   present(contactVC, animated: true)
}


class ContactUsViewController: MFMailComposeViewController {

   override func viewDidAppear(_ animated: Bool) {
      super.viewDidAppear(animated)

      UIApplication.shared.statusBarStyle = .lightContent
   }

   override func viewDidDisappear(_ animated: Bool) {
      super.viewDidDisappear(animated)

      UIApplication.shared.statusBarStyle = .default
   }
}

Moving the styling to `viewDidAppear` works. For anyone else running into this problem in the future. If you don't want to change the style to black after closing the mail sending view, simply omit the entire `viewDidDisappear` function from the code above. — Lukasz, Jul 10 '17 at 10:46
