Google 将地图集成到 SwiftUI 中

Google Maps integration into SwiftUI

我对使用 Xcode 和 SwiftUI 进行编程还很陌生,并且无法将 Google 地图集成到 SwiftUI 项目中。

我将所有正确的 API 键添加到我的 AppDelegate.swift 文件中,并创建了一个名为 GoogMapView 的视图,我试图用它来显示 Google 地图的实例。这是我在 GoogMapView 文件中的代码:

import SwiftUI
import MapKit
import UIKit
import GoogleMaps
import GooglePlaces

struct GoogMapView : UIViewRepresentable {
    func makeUIView(context: Context) -> GMSMapView {
        GMSMapView(frame: .zero)
    }

    func updateUIView(_ view: GMSMapView, context: Context) {
        let camera = GMSCameraPosition.camera(withLatitude: -33.86, longitude: 151.20, zoom: 6.0)
        let mapView = GMSMapView.map(withFrame: CGRect.zero, camera: camera)
        view = mapView

        let marker = GMSMarker()
        marker.position = CLLocationCoordinate2D(latitude: -33.86, longitude: 151.20)
        marker.title = "Sydney"
        marker.snippet = "Australia"
        marker.map = mapView
    }

我一直在 'view = mapView' 收到错误,但我尝试的一切都失败了。知道如何设置它以便我可以在主视图中调用它吗?

我也是一名新 iOS 开发人员。我在调查同样的事情,偶然发现了你的问题。由于我是 iOS 的新手,我不能声称它遵循所有正确的约定,但这段代码可以在基本级别上使用 SwiftUI 在模拟器上显示地图。解决方案基于您的代码和 Matteo 的观察。

import SwiftUI
import UIKit
import GoogleMaps

struct ContentView: UIViewRepresentable {
    let marker : GMSMarker = GMSMarker()

    /// Creates a `UIView` instance to be presented.
    func makeUIView(context: Self.Context) -> GMSMapView {
        // Create a GMSCameraPosition that tells the map to display the
        // coordinate -33.86,151.20 at zoom level 6.
        let camera = GMSCameraPosition.camera(withLatitude: -33.86, longitude: 151.20, zoom: 6.0)
        let mapView = GMSMapView.map(withFrame: CGRect.zero, camera: camera)

        return mapView
    }

    /// Updates the presented `UIView` (and coordinator) to the latest
    /// configuration.
    func updateUIView(_ mapView: GMSMapView, context: Self.Context) {
        // Creates a marker in the center of the map.
        marker.position = CLLocationCoordinate2D(latitude: -33.86, longitude: 151.20)
        marker.title = "Sydney"
        marker.snippet = "Australia"
        marker.map = mapView
    }

}

我遇到了这个问题,所以我更改了参数以匹配。

func updateUIView(_ **view** GMSMapView, context: Self.Context) {

     marker.map = **view** }
