SwiftUI 关闭多个模态表 [英] SwiftUI Dismiss Multiple Modal Sheets
问题描述
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?
推荐答案
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.
