ios - 如何在将 View Controller 推送到另一个 View Controller 时处理 UIParallaxDimmingView？

Question

我需要将 UIParallaxDimmingView 设为白色或透明。

vc1 的白色背景受此 UIParallaxDimmingView 的影响，使其在动画结束后过渡到 vc2 时呈现浅灰色，vc2 获得其白色背景。

我进行了研究，找到了这段代码，但对我不起作用。

func navigationController(_ navigationController: UINavigationController, didShow viewController: UIViewController, animated: Bool) {
    if (navigationController.viewControllers.count > 1)
    {
         self.navigationController?.interactivePopGestureRecognizer?.delegate = self
        navigationController.interactivePopGestureRecognizer?.isEnabled = true;
    }
    else
    {
         self.navigationController?.interactivePopGestureRecognizer?.delegate = nil
        navigationController.interactivePopGestureRecognizer?.isEnabled = false;
    }
}

例如，在推送 viewController 时，只需使用 false 移除动画。简单易行。

navigationController?.pushViewController(YourController, animated: false)
