Question

您好我试图将地图放在子视图中，但是当我在子视图中放置谷歌地图时它不起作用标记并且GPS坐标不起作用

- 与子视图

- 没有子视图

-SWIFT CODE

import UIKit
import GoogleMaps

class HomeViewController: UIViewController, CLLocationManagerDelegate {

    @IBOutlet weak var mapView: GMSMapView!

    let locationManager = CLLocationManager()

    override func viewDidLoad() {
        super.viewDidLoad()
        locationManager.delegate = self
        locationManager.requestAlwaysAuthorization()

                let camera = GMSCameraPosition.cameraWithLatitude(15.4989, longitude: 73.8278, zoom: 6)
                let mapView = GMSMapView.mapWithFrame(CGRectZero, camera: camera)
                mapView.myLocationEnabled = true
//                self.view = mapView
                self.view.addSubview(mapView)
                let marker = GMSMarker()
                marker.position = CLLocationCoordinate2DMake(15.4989, 73.8278)
                marker.title = "Panjim"
                marker.snippet = "Near Don Bosco,Alphran Plaza"
                marker.map?.addSubview(mapView)

    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

}

提前致谢

我找到了解决方案。问题是：我正在创建一个新地图，然后在新地图上添加一个标记。然后用新地图我什么也没做。所以这是我的解决方案：

@IBOutlet weak var subviewMap: GMSMapView!

func loadMap() {
        let camera = GMSCameraPosition.camera(withLatitude: -33.86, longitude: 151.20, zoom: 10.0)
        subviewMap.camera = camera
        let marker = GMSMarker()
        marker.position = CLLocationCoordinate2D(latitude: -33.86, longitude: 151.20)
        marker.title = "Sydney"
        marker.snippet = "Australia"
        marker.map = subviewMap
    }

它有效。

注意：不要忘记将您的子视图提及为IB中的GMSMapView类

以下是添加标记的解决方案

makeprgBuild()

将相机设置为位置

            let marker = GMSMarker()
            marker.position = CLLocationCoordinate2DMake(lat, long)
            marker.appearAnimation = kGMSMarkerAnimationPop
            marker.title = "Marker" // Marker title here
            marker.snippet = "Tap the ↱ Navigate button to start navigating."
            marker.infoWindowAnchor = CGPoint(x: 0.5, y: 0)
            marker.icon = UIImage(named: "marker") //Set marker icon here
            marker.map = self.mapView // Mapview here

我在另一个UIView里面有我的GMSMapView，一切正常。唯一不同的一行是：

marker.map = mapView

Answer 4

after adding marker you should add some delay with this approach i have added 2 marker with bounds 

DispatchQueue.main.async {
            if self.markerArray.count > 1 {
                var bounds = GMSCoordinateBounds()
                for marker in self.markerArray {
                    marker.map = self.mapView
                    bounds = bounds.includingCoordinate(marker.position)
                }
                self.isMovedTheMap = false
                DispatchQueue.main.asyncAfter(deadline: .now() + 0.9, execute: {
                    self.superTopView.fadeOut()
                    let update = GMSCameraUpdate.fit(bounds, withPadding: 80)
                    self.mapView.animate(with: update)
                })
            }
        }

标记未在子视图IOS SWIFT中的谷歌地图中找到
