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

Some times it will not update the status bar style properly. You should use

 [self setNeedsStatusBarAppearanceUpdate];

To say iOS to refresh the status bar style, manually. Hope someone would save some time on knowing it.

[self presentViewController:picker animated:YES completion:^{
    [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
     [self setNeedsStatusBarAppearanceUpdate];
}];

Answer 2

None of above answers are work for me.

I have two issues.

1. Black status bar
2. transparent layer on title bar

Solution

1. Black status - I remove all navigation bar customization

   // comment below line in AppDelegate

   [[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"nav_bg"] forBarMetrics:UIBarMetricsDefault];

2. Transparent title bar - set navigationBarHidden = Yes for MFMailComposeViewController

   composeViewController.navigationBarHidden = YES;

Answer 3

Swift solution. Set View controller-based status bar appearance to YES

import UIKit
import MessageUI
import AddressBookUI

extension MFMailComposeViewController {
    override func preferredStatusBarStyle() -> UIStatusBarStyle {
        return .LightContent
    }

    override func childViewControllerForStatusBarStyle() -> UIViewController? {
        return nil
    }
}

extension ABPeoplePickerNavigationController {
    override func preferredStatusBarStyle() -> UIStatusBarStyle {
        return .LightContent
    }

    override func childViewControllerForStatusBarStyle() -> UIViewController? {
        return nil
    }
}

Answer 4

iOS 7 introduces a method prefersStatusBarHidden, but it won't be so easy to use in this case. You may prefer to use the statusBarHidden property of UIApplication while the modal is presented.

Answer 5

What did the trick for me was:

• Subclass MFMailComposeViewController

• Override the two methods as described in answer 6

  -(UIStatusBarStyle)preferredStatusBarStyle;

  -(UIViewController *)childViewControllerForStatusBarStyle;

• Override viewDidLoad as follows:

  -(void)viewDidLoad {
[super viewDidLoad];
[self preferredStatusBarStyle];
[self setNeedsStatusBarAppearanceUpdate];
}

Answer 6

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
        }
    }
