在SwiftUI中使用NavigationLink导航时如何隐藏TabBar? [英] How to hide the TabBar when navigate with NavigationLink in SwiftUI?

问题描述

我有一个带有2个标签的TabView，每个标签都包含一个NavigationView.导航到另一个视图时，我需要隐藏TabBar.一种解决方案是将TabView放在一个NavigationView内，但是我必须为每个NavigationView设置不同的属性.

I have a TabView with 2 tabs in it, each tab containing a NavigationView. I need to hide the TabBar when navigating to another view. One solution would be to place the TabView inside of one NavigationView, but I have to set different properties for each NavigationView.

TabView(selection: $selectedTab, content: {
            NavigationView {
                VStack {
                    NavigationLink(destination: Text("SecondView Tab1")) {
                        Text("Click")
                    }
                }
            }.tabItem {
                Text("ONE")
            }.tag(0)

            NavigationView {
                VStack {
                    NavigationLink(destination: Text("SecondView Tab2")) {
                        Text("Click")
                    }
                }
            }.tabItem {
                Text("TWO")
            }.tag(1)

        })

P.S.我正在使用Xcode 11 Beta 5

推荐答案

有点晚了，但可以工作，将导航视图放在TabView之前，然后在选项卡式视图中使用导航链接时，将隐藏选项卡按钮.

A little late but it will work, put your NavigationView before the TabView and the tab buttons are going to be hidden when you use a navigation link in your tabbed views.

NavigationView{
    TabView{
        ...
    }
}
