iOS14 导航返回Tabbar消失问题适配

iOS14 iOS14.1版本上均发现,在导航popToRoot返回到时候Tabbar会消失,并无法进行返回操作,解决方法如下:

override func popToRootViewController(animated: Bool) -> [UIViewController]? {
        guard #available(iOS 14, *) else {
             return super.popToRootViewController(animated: animated)
        }
        viewControllers.forEach({$0.hidesBottomBarWhenPushed = false})
        return super.popToRootViewController(animated: animated)
    }
···swift
override func pushViewController(_ viewController: UIViewController, animated: Bool) {
        if self.viewControllers.count == 1{
            viewController.hidesBottomBarWhenPushed = true
        }else{
            viewController.hidesBottomBarWhenPushed = false

        }
        super.pushViewController(viewController, animated: animated)
    }
