iOS15适配 navigationBar 背景色 导航栏标题颜色

iOS15之后发现常规方法navigationBar setBackgroundImage设置了导航栏的背景色之后并没有改变，修改方法如下

if(@available(iOS15.0, *)) {

        UINavigationBarAppearance *appearance = [[UINavigationBarAppearance alloc] init];

        appearance.backgroundImage= [UIImage imageWithColor:kColorVipPayBG];//图片

        appearance.backgroundColor=kColorVipPayBG;//背景色

        appearance.shadowColor = UIColor.clearColor; //阴影

        appearance.titleTextAttributes = @{NSForegroundColorAttributeName : [UIColor whiteColor]};//导航栏标题颜色

        self.navigationController.navigationBar.standardAppearance = appearance;

        self.navigationController.navigationBar.scrollEdgeAppearance = appearance;

    }else{

        // Fallback on earlier versions

        [self.navigationController.navigationBar setBackgroundImage:[UIImage imageWithColor:kColorVipPayBG] forBarMetrics:UIBarMetricsDefault];

        [self.navigationController.navigationBar setShadowImage:[TCUtils imageFromColor:kColorVipPayBG forSize:CGSizeMake(1, 1) withCornerRadius:0]];

    }
