SwiftUI 关闭多个模态表
问题说明
我在我的根视图中使用 .sheet(isPresented: self.$showModal) 来呈现模式.在模态中，我使用 NavigationView 引导用户浏览各种页面(用于用户配置文件构建器).
I am using .sheet(isPresented: self.$showModal) in my root view to present a modal. Within the modal, I am using NavigationView to take the user through various pages (for a user profile builder).
在导航堆栈的最后一页中，我使用了 @Environment(.presentationMode) var presentationMode 和一个调用 self.presentationMode.wrappedValue.dismiss() 的按钮代码> 关闭模式.但是，这只会关闭导航堆栈中的最后一页，而我只是在上一页结束.我想要做的是关闭整个导航堆栈并最终回到根视图.
In the last page of my navigation stack, I am using @Environment(.presentationMode) var presentationMode and a button which calls self.presentationMode.wrappedValue.dismiss() to dismiss the modal. However, this only dismisses the last page in the navigation stack, and I just end up at the previous page. What I want to do is dismiss the entire navigation stack and end up back at the root view.
向下滑动以关闭模态会产生所需的结果，但我想使用按钮以编程方式执行此操作.
Swiping down to dismiss the modal produces the desired result, but I want to do this programatically with the button.
这在 SwiftUI 中目前是否可行，或者这是在模式表中使用 NavigationView 的问题吗?
Is this currently possible in SwiftUI, or is this a problem with using NavigationView within a modal sheet?
正确答案
您可以将 showModal 作为绑定传递到以下屏幕中，而不是使用presentationValue 将 showModal 设置为 false.
You can pass showModal as a binding into the following screens and instead of using presentationValue set showModal to false.
