Change status bar colours in MFMailComposeViewController through UIActivityViewController

Question

I am trying to change the colour of the navigation bar buttons, navigation bar tint colour and text colour, however I don't seem to be getting anywhere. The MFMailComposeViewController is being activated via a UIActivityViewController and I have tried a few different methods that have worked before (not through a UIActivityViewController though).

This is my current code:

    UINavigationBar.my_appearanceWhenContainedIn(MFMailComposeViewController).barTintColor = UIColor.blackColor()

This was suggested here. I have also tried this:

    activityVC.navigationController?.navigationBar.tintColor = UIColorFromRGB(0x0096FF)
    activityVC.navigationController?.navigationBar.barTintColor = UIColor.whiteColor()

I'm also looking to change the status bar colour.

Anyone have any ideas?

UPDATE:

I fixed the navigation bar issues for the buttons and title, but still looking for a solution to the status bar. Doing this doesn't work:

    self.presentViewController(activityVC, animated: true, completion: { () in
        UIApplication.sharedApplication().setStatusBarStyle(UIStatusBarStyle.LightContent, animated: true)
    })

You can subclass the MFMailViewController and override its viewWillAppear method

override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)
    UIApplication.sharedApplication().statusBarStyle = UIStatusBarStyle.LightContent
    self.navigationController.navigationBar.translucent = false
    self.navigationController.navigationBar.opaque = false
    self.navigationController.navigationBar.barTintColor = UIColor.blueColor()
}

Since you only want the status bar to be lightcontentwhen the MFMailComposeViewController is active, you shouldn't put the

UIApplication.sharedApplication().statusBarStyle = UIStatusBarStyle.LightContent

into your app delegates didFinishLoading. This would set it lightContent for your whole application.

for iOS8 you use barTintColor to change the color of status

    NSString *invitationText = @"test";
   [UINavigationBar appearance].barTintColor = [UIColor whiteColor];
   MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init];
   mc.mailComposeDelegate = self;
   [mc setSubject:@"Test "];
   [mc setMessageBody:invitationText isHTML:YES];
   [self presentViewController:mc animated:YES completion:NULL];

Go to your app delegate file and add these lines to your didFinishLaunchingWithOptions :) It will update the status bar color for all view controllers.

UIApplication.sharedApplication().statusBarStyle = UIStatusBarStyle.LightContent

Additionally in your info.plist file add a new key called "View controller-based status bar appearance" and set the value to "NO"

UPDATE

To set diffrent styles between views try this:

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

Then you can return light or dark depending on what you are trying to achieve :)

I have this, but I need the status bar style to be different between view controllers. – Kline

MFMailComposeViewController sets its own Status-Bar style, which you don't have access to. You can probably dig into some private APIs to do this, but then your app definitely will be rejected by Apple.

As a side note though, you shouldn't be changing anything about Apple provided UIViewController(s). They look that way because they're styled after the original app. It's meant to give users a sense of location and direction in an app. Apple may reject your app, too, because you've changed their stuff.

While that may be the case, I've had many other apps approved that do exactly the same thing so I'm not too worried about it being rejected. – Kline
