iPhone X - 设置主页指示器周围区域的颜色

当我尝试将工作表与 iPhone X 的安全区域对齐时，我对 Xcode 还很陌生，它在工作表下方留下了一个透明区域。

有没有办法设置该区域的填充而不扩展纸张或在安全区域之外对齐？

这是我的小扩展。 如果有人可以建议改进以不通过“幻数”标签访问添加的视图 - 欢迎！

extension UIViewController {

private static let insetBackgroundViewTag = 98721 //Cool number

func paintSafeAreaBottomInset(withColor color: UIColor) {
    guard #available(iOS 11.0, *) else {
        return
    }
    if let insetView = view.viewWithTag(UIViewController.insetBackgroundViewTag) {
        insetView.backgroundColor = color
        return
    }

    let insetView = UIView(frame: .zero)
    insetView.tag = UIViewController.insetBackgroundViewTag
    insetView.translatesAutoresizingMaskIntoConstraints = false
    view.addSubview(insetView)
    view.sendSubview(toBack: insetView)

    insetView.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true
    insetView.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true
    insetView.trailingAnchor.constraint(equalTo: view.trailingAnchor).isActive = true
    insetView.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor).isActive = true

    insetView.backgroundColor = color
}

}
