我有数组中的纬度和经度。我想在 Google 地图中显示多个标记

Question

我在数组中有纬度和经度的数量。我想在 Google 地图中显示多个标记。我是编程新手。

**** 我当前的代码****

导入 UIKit 导入 Google地图

let mapView = GMSMapView()

class ViewController: UIViewController {

let lattitudeary = ["28.5355","28.7041","29.9457","30.0869"]
let longitudeary = ["77.3910","77.1025","78.1642","78.2676"]

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.


    view = mapView

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



//    var coords = [[-33.86,151.20],[28.5355,77.1025],[29.9457,78.1642]]

    var coords = [[lattitudeary.count],[longitudeary.count]]

    for coord in coords {
        var marker = GMSMarker()
        marker.position = CLLocationCoordinate2D(latitude: CLLocationDegrees(coord[0]), longitude: CLLocationDegrees(coord[1]))
        marker.map = mapView

    }

}

首先将 Google 地图与您的应用集成 Google Maps iOS SDK

然后尝试在地图上添加标记 Adding a Map with a Marker

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

最后使用for循环将多个标记添加到地图中。 Swift Control Flow

var coords = [[-33.86,151.20],[-33.85,151.18],[-33.76,151.14]]
for coord in coords {
var marker = GMSMarker()
marker.position = CLLocationCoordinate2D(latitude: coord[0], longitude: coord[1])
marker.map = mapView
}

我有数组中的纬度和经度。我想在 Google 地图中显示多个标记

I've number of latitude and longitude in array. I want to display multiple markers in Google Map
