Code:

if (@available(iOS 15.0, *)) {
        UINavigationBarAppearance *navigationBarAppearance = [UINavigationBarAppearance new];
        navigationBarAppearance.backgroundColor = UIColor.white;
        self.navigationController.navigationBar.scrollEdgeAppearance = navigationBarAppearance;
        self.navigationController.navigationBar.standardAppearance = navigationBarAppearance;
}

这个问题应该由使用方自己处理，我无法处理所有场景，建议在启动时统一设置 appearance：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // setup appearance
    if (@available(iOS 15.0, *)) {
        [[UINavigationBar appearance] setScrollEdgeAppearance:({
            UINavigationBarAppearance *app = [UINavigationBarAppearance new];
            [app configureWithDefaultBackground];
            // init app property
            // app.backgroundColor = xxx; app.shadowColor = xxx;
            app;
        })];
    } else {
        // Fallback on earlier versions
    }

    return YES;
}

    }

iOS15 这样设置全局颜色后，某一页面想换导航栏颜色，怎么办
