SwiftUI无法使用NavigationLink来回导航

Question

在gif中显示，一旦导航并关闭新视图，便无法导航回去！这是SwiftUI错误还是滥用NavigationLink？

struct ContentView: View {
    var body: some View {
        return NavigationView {
            NavigationLink(destination: FakeView1()) {
                Text("Navigate")
            }
        }
    }
}

struct FakeView1: View {
    var body: some View {
        Text("Hey")
    }
}

Answer 1

这似乎是swiftUI错误。我也遇到了同样的问题，因此，我已经使用了这种解决方法。

struct ContentView: View {

@State var isFakeActive: Bool = false

var body: some View {
    NavigationView {
        NavigationLink(destination: FakeView1(isFakeActive: self.$isFakeActive), isActive: self.$isFakeActive) {
            Text("Navigate")
        }
    }
  }
}

对于您的FakeView1类。

struct FakeView1: View {

@Binding var isFakeActive: Bool

var body: some View {
    Text("Hey")
        .navigationBarItems(leading: Button(action: {
            self.isFakeActive = false
        }, label: {
            HStack {
                Image(systemName: "arrow.left")
                Text("Back")
            }
        }))
    }
}

我已经测试过，并且工作正常。
