Change MFMailComposeViewController's UINavigationBar color in iOS7

Question

I am trying to update my app for iOS7, however I am unable to set the colour of the UINavigationBar at the top of the screen. I have tried the classic approach...

[mailer.navigationBar setTintColor:[UIColor darkGreyColour]];

...however it didn't work. I have also tried calling setBarTintColor instead, however that didn't seem to work either.

Does anyone know if its possible to set the colour and if so how?

Answer 1

I had your same problem when updating my application for iOS 7.
I solved using this line of code (if you use images):

[[UINavigationBar appearance] setBackgroundImage:@"myImage" forBarPosition:UIBarPositionTopAttached barMetrics:UIBarMetricsDefault];

or this one if you are not using images:

[[UINavigationBar appearance] setBarTintColor:[UIColor blueColor]];

I placed then in AppDelegate, just before returning application:didFinishLaunchingWithOptions:

Hope this helps!
