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

In my case, I was using "view controller-based status bar appearance" and presenting a modal view controller with a custom segue transition and then presenting the MFMailComposeViewController from there. In this situation, by default, iOS only respects/uses the presenting or "root" view controller's preferredStatusBarStyle method.

So once I overrode childViewControllerForStatusBarStyle in my root view controller and preferredStatusBarStyle in my modal view controller, everything worked as expected... something like this:

// in RootViewController.m ...
- (UIViewController *)childViewControllerForStatusBarStyle {
    return self.modalViewController;
}

// in ModalViewController.m ...
- (UIStatusBarStyle)preferredStatusBarStyle {
    if (self.mailController != nil)
        return UIStatusBarStyleDefault;
    return UIStatusBarStyleLightContent;
}
