多行文本在SwiftUI中列表内的NavigationLink中不起作用 [英] Multiline Text does not work in a NavigationLink inside of a List in SwiftUI

问题描述

多行Text似乎不起作用.

这是代码:

struct ContentView : View {
    var body: some View {
        List(1...5) { _ in
            NavigationLink(destination: EmptyView()) {
                Text("Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.")
                    .lineLimit(nil)
            }
        }
    }
}

卸下NavigationLink，Text的行为符合预期.

Removing the NavigationLink, the Text behaves as expected.

是否可以解决此问题，或者这是一个错误?

Is there a way to fix this, or is this a bug?

推荐答案

UPDATE

似乎Beta 5解决了该错误！

UPDATE

It seems Beta 5 has solved this bug!

Beta 4和早期版本的解决方法:

似乎NavigationLink已损坏".但是您可以改用 DynamicNavigationDestinationLink .我知道它太冗长，但是如果您需要出路，就可以在这里找到.至少要等到NavigationLink更好地工作为止.

It seems NavigationLink is "broken". But you can use DynamicNavigationDestinationLink instead. I know it's too verbose, but if you need a way out, here you have it. At least until NavigationLink works better.

struct ContentView: View {

    var body: some View {
        NavigationView {
            TopView().navigationBarTitle(Text("Top View"))
        }
    }
}

struct TopView: View {

    let detailView = DynamicNavigationDestinationLink(id: \String.self) { data in
        DetailView(passedData: data)
    }

    var body: some View {
        List(1...5) { i in
            Text("Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.")
                .lineLimit(nil)
                .tapAction { self.detailView.presentedData?.value = "Detail for Row #\(i)" }
        }
    }
}

struct DetailView: View {
    let passedData: String

    var body: some View {
        Text(passedData)
    }
}
