How to change color of navigation bar in mfmessagecomposeviewcontroller while presenting it in ios 9

问题

        MFMessageComposeViewController *messageController = [[MFMessageComposeViewController alloc]init];
        [UINavigationBar appearance].barTintColor = [UIColor colorWithRed:0.0f/255.0f green:127.0f/255.0f blue:254.0f/255.0f alpha:1.0];
        [[messageController navigationBar] setTintColor: [UIColor whiteColor]];
        messageController.messageComposeDelegate = self;
        [messageController setBody:message];
        [messageController navigationBar].translucent =NO;                                             
        [messageController.navigationBar setBarTintColor:[UIColor colorWithRed:0.0f/255.0f green:127.0f/255.0f blue:254.0f/255.0f alpha:1.0]];
        // Present message view controller on screen
        [self presentViewController:messageController animated:YES completion:^{
        [messageController navigationBar].translucent = NO;
        }];

I have been using this code. Please let me know if anything is missing.

You just need to add two lines to change navigation bar color.

For MFMailComposeViewController.

MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init];

[mc.navigationBar setTintColor:[UIColor whiteColor]];//cancel button will be of white color.
[mc.navigationBar setBarTintColor:[UIColor blackColor]];//bar color will be black.

if (mc != nil)
        {
            mc.mailComposeDelegate = self;
            [mc setSubject:emailTitle];
            [mc setMessageBody:bodyText isHTML:YES];
            [mc setToRecipients:toRecipents];

            [self presentViewController:mc animated:YES completion:nil];

        }

For MFMessageComposeViewController

Create one method like below for changing navigation bar color.

- (void)setNavBarColor:(UIColor *)navBarColor titleColor:(UIColor *)titleColor {
    [[UINavigationBar appearance] setBarTintColor:navBarColor];
    [[UINavigationBar appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                          [UIFont fontWithName:@"Futura-Medium" size:17.0f],
                                                          UITextAttributeFont,
                                                          titleColor,
                                                          UITextAttributeTextColor,
                                                          nil]];
}

And write this method before you initialise MFMessageComposeViewController.(This is very important otherwise it will not work)

This code work for me in ios 9.

May be it will help you.
