【问题标题】：Make Info window Marker Google Maps Always Appear Swift使信息窗口标记谷歌地图总是出现斯威夫特

【问题描述】：

我有点击后显示的信息窗口，但如何让它始终出现？无需用户点击标记。我正在使用谷歌地图。

这是我的代码：

    mapView.delegate = self
    let camera = GMSCameraPosition.camera(withLatitude: coordinate.lat, longitude: coordinate.long, zoom: 20)
    mapView.animate(to: camera)

    for state in states {
        let marker = GMSMarker()
        marker.position = CLLocationCoordinate2DMake(state.lat, state.long)
        print(marker.position)
        marker.title = "Country"
        marker.snippet = "Places"
        marker.map = mapView
        mapView.selectedMarker = marker
        marker.map = mapView

    }

感谢之前

【解决方案1】：

首先我们需要添加一个标记。

let position = CLLocationCoordinate2D(latitude: 10, longitude: 10)
let marker = GMSMarker(position: position)
marker.title = "Hello World"
marker.map = mapView

我们可以通过以下方式自定义标记图像：-

let position = CLLocationCoordinate2D(latitude: 51.5, longitude: -0.127)
let london = GMSMarker(position: position)
london.title = "London"
london.icon = UIImage(named: "house")
london.map = mapView
//To change the Marker Opacity use below
marker.opacity = 0.6

旋转标记：-

let position = CLLocationCoordinate2D(latitude: 51.5, longitude: -0.127)
let degrees = 90.0
let london = GMSMarker(position: position)
london.groundAnchor = CGPoint(x: 0.5, y: 0.5)
london.rotation = degrees
london.map = mapView

添加信息窗口：-

let position = CLLocationCoordinate2D(latitude: 51.5, longitude: -0.127)
let london = GMSMarker(position: position)
london.title = "London"
london.snippet = "Population: 8,174,100"
london.map = mapView

设置信息窗口自动刷新

marker.tracksInfoWindowChanges = true

更改信息窗口的位置

let position = CLLocationCoordinate2D(latitude: 51.5, longitude: -0.127)
let london = GMSMarker(position: position)
london.title = "London"
london.snippet = "Population: 8,174,100"
london.infoWindowAnchor = CGPoint(x: 0.5, y: 0.5)
london.icon = UIImage(named: "house")
london.map = mapView

【解决方案2】：

尝试将 mapView.selectedMarker = marker 移动到委托函数 mapView(_ mapView: GMSMapView, didTap marker: GMSMarker) -> Bool 函数
