Description Michael Dimoudis 2016-06-23 04:17:01 UTC
Hi

I  mentioned this in the forum, not sure if it's been actioned (I saw my first issue was actioned on GitHub). https://forums.xamarin.com/discussion/comment/204646/#Comment_204646

The issue is:
Changing the font on UINavigationBar.Appearance.SetTitleTextAttributes affects the UITabBar too.

If I change the font for UINavigationBar it ALSO affects UITabBar.

UITabBarItem.Appearance.SetTitleTextAttributes does not work anymore.

Below is my code in AppDelegate.cs

UINavigationBar.Appearance.SetTitleTextAttributes (new UITextAttributes {
    TextColor = UIColor.White,
    Font = UIFont.FromName (Theme.IOS_FONT_NAME_LIGHT, 20f)
});

// Below code is broken now
UITabBarItem.Appearance.SetTitleTextAttributes (new UITextAttributes {
    Font = UIFont.FromName (Theme.IOS_FONT_NAME_NORMAL, 11f)
}, UIControlState.Normal);

UITabBarItem font becomes what UINavigationBar font is, with no way of updating UITabBarItem back to how it should behave.

Hi Samantha. My bug relates to a font issue, not color issue. Hence why I created this bug report as I haven't seen it specifically reported yet. 

It relates to the UINavigationBar font also affecting the UITabBarItem font.

Is this font issue related to the duplicate bug you linked to? If it is sorry but I couldn't see font mentioned anywhere. If it's not then I can create a repro project, it should be pretty easy to repro it.

Hi Michael!

The bug had the same root cause, and it should be resolved by the same fix. Thank you for your report, though. We appreciate the thoroughness!!
