Question

I\'m aware that I can individually change the font of a navigation bar as outlined in this answer: Change the navigation bar's font

Currently I\'m using a more globa

Answer 1

Above answers with updates for deprecated keys and use of NSShadow:

NSShadow *shadow = [[NSShadow alloc] init];
shadow.shadowColor = [UIColor blackColor];
shadow.shadowBlurRadius = 0.0;
shadow.shadowOffset = CGSizeMake(0.0, 2.0);
[[UINavigationBar appearance] setTitleTextAttributes: @{
                     NSForegroundColorAttributeName : [UIColor blackColor],
                                NSFontAttributeName : [UIFont fontWithName:@"Helvetica-Light" size:0.0f],
                              NSShadowAttributeName : shadow
}];

Also setting the font size to 0 so it automatically resizes based on navigation bar orientation/height.
