MFMailComposeViewController in iOS 7 statusbar are black

Question

i have a feedback button in my ios 7 application with MFMailComposeViewController. After the user click this button the mailcomposer open but the statusbar changed to black.

Answer 1

It seems that initializing the MFMailComposeViewController UIApplication.shared.statusBarStyle will change to .default... so, saving the state before and setting it again after presentation solved the problem for me:

    // save the state, otherwise it will be changed
    let sbs = UIApplication.shared.statusBarStyle

    let mailComposerVC = MailComposerVC()
    mailComposerVC.navigationBar.barTintColor = UINavigationBar.appearance().barTintColor
    mailComposerVC.navigationBar.tintColor = UINavigationBar.appearance().tintColor
    mailComposerVC.navigationBar.barStyle = UINavigationBar.appearance().barStyle

    if MFMailComposeViewController.canSendMail() {
        APP_ROOT_VC?.present(mailComposerVC, animated: true, completion: {
            // reapply the saved state
            UIApplication.shared.statusBarStyle = sbs
        })
    }

    public class MailComposerVC: MFMailComposeViewController {

        public override var preferredStatusBarStyle: UIStatusBarStyle {
            return UIApplication.shared.statusBarStyle
        }
        public override var childViewControllerForStatusBarStyle : UIViewController? {
            return nil
        }
    }
