颜色可以改变，但是图片目前是改不了，一直都是 light 模式下的图片

试试如下代码

- (void)traitCollectionDidChange:(UITraitCollection *)previousTraitCollection
{
    [super traitCollectionDidChange:previousTraitCollection];

    if (@available(iOS 13.0, *)){

        NSArray *navcs = self.viewControllers;
        if (previousTraitCollection.userInterfaceStyle == UIUserInterfaceStyleDark) {

            UIImage *selectImage = [[UIImage imageNamed:@"icon_line_sel_w"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

            for (int i = 0; i < navcs.count; i++) {
                UINavigationController *navi = navcs[i];
                navi.tabBarItem.selectedImage = selectImage;
            }

        } else {
            NSArray *navcs = self.viewControllers;

            UIImage *selectImage = [[UIImage imageNamed:@"icon_line_sel"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

            if (previousTraitCollection.userInterfaceStyle == UIUserInterfaceStyleLight) {

                for (int i = 0; i < navcs.count; i++) {
                    UINavigationController *navi = navcs[i];
                    navi.tabBarItem.selectedImage = selectImage;

                }
            }

        }
    }
}
