let mapView = GMSMapView.mapWithFrame(CGRect.zero, camera: camera)
mapView.myLocationEnabled = true
view = mapView
// Creates a marker in the center of the map.
let marker = GMSMarker()
marker.position = CLLocationCoordinate2D(latitude: -33.86, longitude: 151.20)
marker.title = "Sydney"
marker.snippet = "Australia"
marker.map = mapView
// Create a rectangular path

我需要在多边形的中心添加一个标记。点击标记，我需要显示infowindow。这可能吗？
答案 0 :(得分：0)
可以在多边形的中心添加标记，但您必须自己计算。正如Daniel's answer中所述，使用创建矩形路径的坐标，您可以使用getCenter()类中的LatLngBounds方法来获取地图的中心。另请查看LatLngBounds class。
至于在点击标记时显示InfoWindow，已在the documentation中讨论过。
let position = CLLocationCoordinate2D(latitude: 51.5, longitude: -0.127)
let london = GMSMarker(position: position)
london.title = "London"
london.map = mapView
请注意，一次只会显示1个InfoWindow，如果title和snippet都为空或nil，则不会显示。
快乐的编码！
