How To Change Shell Tab Font to Custom Font - iOS SDK 15

Question

Hi There,

In SDK 14, I was able to change the font of the shell tab by simply having the font *.ttf in the resources folder and adding these two lines in FinishedLaunching

UITabBarItem.Appearance.SetTitleTextAttributes(new UITextAttributes() { Font = UIFont.FromName("MY_FONT_NAME", 10), }, UIControlState.Normal);  
UITabBarItem.Appearance.SetTitleTextAttributes(new UITextAttributes() { Font = UIFont.FromName("MY_FONT_NAME", 10), }, UIControlState.Selected);   

However, when compiling with SDK 15, this no longer works! Any quick workaround to change the font of the shell?
Thanks,

Hello,

You could use Renderer to implement this function.

Referring to this official sample customize-tabs, we could find the details about how to deal with it in ExtendedTabbedPageRenderer.cs.

Another way is setting the UITabBarAppearance property manually, you can refer the following key code.

   private static UITabBarAppearance tabBarAppearance()  
   {  
       var appearance = new UITabBarAppearance();  
       appearance.ConfigureWithOpaqueBackground();  
       appearance.BackgroundColor = UIColor.White;  
       appearance.StackedLayoutAppearance.Normal.TitleTextAttributes = new UIStringAttributes() { Font = UIFont.FromName("MY_FONT_NAME", 10), };  
       appearance.StackedLayoutAppearance.Selected.TitleTextAttributes = new UIStringAttributes() { Font = UIFont.FromName("MY_FONT_NAME", 10), };  
       return appearance;  
   }  
     
   ...  
   tabBar.ScrollEdgeAppearance = appearance;  
   tabBar.StandardAppearance = appearance;
