Apply Attributes to Navigationcontroller instance.

if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7")) {
    NSDictionary *navbarTitleTextAttributes = [NSDictionary dictionaryWithObjectsAndKeys:
                                               [UIColor whiteColor],
                                               NSForegroundColorAttributeName,
                                               [UIFont fontWithName:@"MyFavoriteFont" size:20.0],
                                               NSFontAttributeName,
                                               nil];
    [self.transitionNavController.navigationBar setTitleTextAttributes:navbarTitleTextAttributes];
}

Hope this helps...
