This question has nothing to do with using the MFMailComposeViewController
. If you wish to customize the appearance of a UINavigationBar
, then you may need to set more properties than just the background image. You should also setup the titleTextAttributes
.
// Use whatever color is appropriate
NSDictionary *attributes = @{ UITextAttributeTextColor: [UIColor blueColor] };
[[UINavigationBar appearance] setTitleTextAttributes:attributes];
There are other attributes such as the font and shadow colors. Feel free to set the ones you need.
