iOS15 导航栏和Tabbar变成白色

iOS15的新坑。废话就不说了。

我的修改方式：

1.导航栏

BaseNavigationController的viewDidLoad方法里添加：

if (@available(iOS 13.0, *)) {
        UINavigationBarAppearance *appearance = [UINavigationBarAppearance new];
        [appearance configureWithOpaqueBackground];
        appearance.backgroundColor = [UIColor hexColor:0x111423]; // 项目导航的颜色
        self.navigationBar.standardAppearance = appearance;
        self.navigationBar.scrollEdgeAppearance=self.navigationBar.standardAppearance;
    }

2.Tabbar

BaseTabBarController 的 viewDidLoad方法里添加：

if (@available(iOS 13.0, *)) {
        UITabBarAppearance *appearance = [UITabBarAppearance new];
        [appearance configureWithOpaqueBackground];
        appearance.backgroundColor = [UIColor hexColor:0x111423];
        self.tabBar.standardAppearance = appearance;
        /// 这里有点区别。导航栏是iOS13开始。这里是iOS15才有的
        if (@available(iOS 15.0, *)) {
            self.tabBar.scrollEdgeAppearance = self.tabBar.standardAppearance;
        }
    }

完美解决
