我找到了

        UITabBarAppearance *appearance = UITabBarAppearance.new;
        NSMutableParagraphStyle *par = [[NSMutableParagraphStyle alloc]init];
        par.alignment = NSTextAlignmentCenter;
       
        UITabBarItemStateAppearance *normal = appearance.stackedLayoutAppearance.normal;
   if (normal) {
   normal.titleTextAttributes =    @{NSFontAttributeName : [UIFont systemFontOfSize:font]};
   }
   
   UITabBarItemStateAppearance *selected = appearance.stackedLayoutAppearance.selected;
   if (selected) {
        selected.titleTextAttributes =  @{NSFontAttributeName : [UIFont systemFontOfSize:font]};
   }
   
   tabar13.standardAppearance = appearance;
