我的应用程序用户界面层次结构看起来像如图所示。UItabbarcontroller -〉navigation-controllers -〉view-controllers。

我面临的问题是hidesBottomBarWhenPushed不工作时，我试图推动一个新的控制器从第一VC按钮点击

if let newVc = UIStoryboard.homeSB.instantiateViewController(withIdentifier: NewViewController.identifier()) as? NewViewController{
    self.navigationController?.hidesBottomBarWhenPushed = true
    self.navigationController?.pushViewController(viewAllVc, animated: true)
}

Tabbar仍在NewVc中显示

//在要隐藏tabBar的视图控制器中使用此方法

override var hidesBottomBarWhenPushed: Bool {
    get {
        return navigationController?.topViewController == self
    }
    set {
        super.hidesBottomBarWhenPushed = newValue
    }
}

要在new VC中隐藏选项卡栏，可以在viewDidLoad（）中调用：

self.tabBarController?.tabBar.isHidden = true

另外，你应该从VC调用hidesBottomBarWhenPushed方法，而不是从导航控制器调用：

if let newVc = UIStoryboard.homeSB.instantiateViewController(withIdentifier: NewViewController.identifier()) as? NewViewController{
newVc.hidesBottomBarWhenPushed = true
self.navigationController?.pushViewController(viewAllVc, animated: true) 
}

此外，您可以在新的VC故事板上制作它：

在导航栏中添加这些代码。雨燕

override func pushViewController(_ viewController: UIViewController, animated: Bool) {
        if children.count > 0 {
            viewController.hidesBottomBarWhenPushed = true
        }
        super.pushViewController(viewController, animated: animated)
    }
