为什么VisionOS没有MapKit Annotation点击交互支持？

Question

更新：为了防止提供有关上下文的错误信息，请阅读我上面添加的答案。

我正在尝试将当前生产就绪的 iOS/iPadOS 17 应用程序调整为visionOS，并且我正在尝试直接运行适用于 Apple Vision Pro（专为 iPad 设计）目标的应用程序。

我有一个底部工作表，可以通过点击地图注释来显示地图项目详细信息。底部工作表可以通过正常的按钮操作正确打开，但不能通过包装按钮操作的注释打开。它在 iOS/iPadOS 上按预期弹出，但在 VisionOS 上却没有。

struct SomeAnnotation: Identifiable, Hashable {
    let id: UUID
    let title: String?
    let coordinate: CLLocationCoordinate2D
    let text: String
    
    func hash(into hasher: inout Hasher) {
        hasher.combine(id)
    }
    
    static func == (lhs: SomeAnnotation, rhs: SomeAnnotation) -> Bool {
        return lhs.id == rhs.id
    }
}

struct ContentView: View {
    @State var position: MapCameraPosition = .automatic
    @State var selected: SomeAnnotation?
    @State private var planBottomSheet: Bool = false
    
    let annotations: [SomeAnnotation] = [
        SomeAnnotation(
            id: UUID(),
            title: "Location 1",
            coordinate: CLLocationCoordinate2D(
                latitude: 43.64191952505181,
                longitude: -79.38918661813415
            ),
            text: "Text 1"
        ),
        SomeAnnotation(
            id: UUID(),
            title: "Location 2",
            coordinate: CLLocationCoordinate2D(
                latitude: 43.64083254041681,
                longitude: -79.3859357809321
            ),
            text: "Text 2"
        )
    ]
    
    var body: some View {
        Map(position: $position) {
            ForEach(annotations, id: \.self) { result in
                Annotation(result.title!, coordinate: result.coordinate) {
                    Button(action: {
                        selected = (selected == result ? nil : result)
                    }) {
                        Image(systemName: "bolt.car.circle.fill")
                            .resizable()
                            .foregroundStyle(.red)
                            .frame(width: 36, height: 36)
                            .background(.white)
                            .clipShape(.circle)
                    }
                }
            }
        }
        .sheet(isPresented: $planBottomSheet) {
            SomeView(bottomSheet: $planBottomSheet) // just for an example
        }
    }
}

struct SomeView: View {
    @Binding var bottomSheet: Bool
    var body: some View {
        VStack {
            Text("This is some view")
        }
    }
}

#Preview {
    ContentView()
}

但是，它适用于预期的以下按钮操作，并且可以重现问题并查看以下代码按钮操作，您可以将下面的代码复制/粘贴到身体上方；

var routePlannerButton: some View {
        Button(action: {
            planBottomSheet = true
            if mapViewModel.planDetentCondition {
                mapViewModel.planBottomSheetDetent = .large
            } else {
                mapViewModel.planBottomSheetDetent = .medium
            }
        }) {
            Image(systemName: "point.bottomleft.forward.to.arrowtriangle.uturn.scurvepath.fill")
                .resizable()
                .aspectRatio(contentMode: .fit)
                .frame(width: 20, height: 20)
                .padding()
        }
        .sheet(isPresented: $planBottomSheet) {
            RoutePlannerView(
                planBottomSheetDetent: $mapViewModel.planBottomSheetDetent,
                planBottomSheet: $planBottomSheet,
                isNavigating: $isNavigating,
                showingDetails: $showingRouteDetails
            )
            .presentationDetents(
                [mapViewModel.planBottomSheetDetent, .large, .medium],
                selection: $mapViewModel.planBottomSheetDetent
            )
            .presentationContentInteraction(.resizes)
            .presentationBackgroundInteraction(.enabled(upThrough: .medium))
            .presentationDragIndicator(.visible)
        }
    }

Answer 1

好吧，问题与 VisionOS SwiftUI iOS 17 地图注释支持无关，但我看到的问题是我没有执行任何操作来触发注释中的 BottomSheet。我的 Map() 还应该跟踪选择。通过选择：在注释上加上 .tag，我根本不需要注释标签中的按钮。另外，我在地图中循环两种不同的类型，而 $selection 正在寻找单一类型。因此充电器的标签将被忽略。
