MFMailComposeViewController in iOS 7 statusbar are black

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. Have anybody a idea what can i do?

i have this problem only with ios7. i customizing my app for ios7.

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

            [mailController setSubject:@"Feedback"];
            // Fill out the email body tex
            NSString *emailBody = [NSString stringWithFormat:@"testest"],
                                   [UIDevice currentDevice].model,
                                   [UIDevice currentDevice].systemVersion];
            [mailController setMessageBody:emailBody isHTML:NO];
            [mailController setToRecipients:[NSArray arrayWithObjects:@"[email protected]",nil]];

            dispatch_async(dispatch_get_main_queue(), ^{
                [self presentModalViewController:mailController animated:YES];
}

Solution 1:

Set the UIApplication statusBarStyle in the completion block of presentViewController for your MFMailComposeViewController. i.e.

    MFMailComposeViewController *mailVC = [[MFMailComposeViewController alloc] init];
    [self.navigationController presentViewController:mailVC animated:YES completion:^{
        [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
    }];

You may also need to add and/or set "View controller-based status bar appearance" to NO in your Info.plist file.

Solution 2:

Try to add category to MFMailComposeViewController

EDIT: this solution works if "View controller-based status bar appearance" == YES

@implementation MFMailComposeViewController (IOS7_StatusBarStyle)

-(UIStatusBarStyle)preferredStatusBarStyle
{
   return UIStatusBarStyleLightContent;
}

-(UIViewController *)childViewControllerForStatusBarStyle
{
   return nil;
}

@end

Solution 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
    }
}

Solution 4:

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];
}

Solution 5:

Solution for Swift3

Add this to your ViewController:

extension MFMailComposeViewController {
    open override var preferredStatusBarStyle: UIStatusBarStyle {
        return .lightContent
    }
    open override var childViewControllerForStatusBarStyle: UIViewController? {
        return nil
    }
}

Set View controller-based status bar appearance >> YES as below:

Another cleaner solution that may not change other settings in your app. While presenting the Mail VC change the status bar in the completion block:

controller.present(mailComposeViewController, animated: true) {
            UIApplication.shared.statusBarStyle = .lightContent
        }
