Question

昨天Xcode 11.3发布，出现了新问题，如果您按DetailView并使用默认的后退按钮取回，则您无法再次按自定义按钮再按一次DetailView，是否有任何建议？

class Model: ObservableObject {
    @Published var isPushed = false
}

struct ContentView: View {
    @EnvironmentObject var model: Model

    var body: some View {
        NavigationView {
            VStack {
                Button("push") {
                    self.model.isPushed = true
                }

                NavigationLink(destination: DetailView(), isActive: $model.isPushed) { EmptyView() }
            }
        }
    }
}

struct DetailView: View {
    @EnvironmentObject var model: Model

    var body: some View {
        Button("get me back") {
            self.model.isPushed = false
        }
    }
}

同样的问题

struct ContentView: View {

    var body: some View {
        NavigationView {
            VStack {
                NavigationLink(destination: Text("Pushed")) { Text("push") }
            }
        }
    }
}

您不是第一个问过this question的人。尝试降级xCode。我认为Apple应该在新的更新中修复此错误，我也很快会在Apple反馈助手中撰写。

更新：已发送反馈给Apple

Xcode 11.3 / iOS 13.3 NavigationLink仅被推送一次
