MKMapView 顶部的 SwiftUI 按钮不会被触发

Question

我在 MKMapView 上有一个按钮。但是按钮在点击时不会被触发。你知道少了什么吗？

MapView.swift

import SwiftUI
import UIKit
import MapKit

struct MapView: UIViewRepresentable {

    func makeUIView(context: Context) -> MKMapView {
        let mkMapView = MKMapView()
        return mkMapView
    }
    
    func updateUIView(_ uiView: MKMapView, context: Context) { }
    
    func makeCoordinator() -> Coordinator {
        Coordinator()
    }
    class Coordinator: NSObject, MKMapViewDelegate { }
}

ContentView.swift

import SwiftUI

struct ContentView: View {
    var body: some View {
        ZStack {
            MapView()
            Button(action: {
                print("Tapped")
            }) {
                Image(systemName: "lock.fill")
            }
        }
    }
}

让它更内在一点 space 以便更好地识别。这是固定和测试变体 (Xcode 12 / iOS 14):

struct TestButtonWithMap: View {
    @State private var locked = true
    var body: some View {
        ZStack {
            MapView()
            Button(action: {
                print("Tapped")
                self.locked.toggle()
            }) {
                Image(systemName: locked ? "lock.fill" : "lock.open")
                    .padding()      // << here !!
            }
        }
    }
}
