将对象传递到Google Maps SDK中的自定义视图

GMSMapViewDelegate具有委托功能，可让您将customView作为信息窗口返回。

optional public func mapView(_ mapView: GMSMapView, markerInfoWindow marker: GMSMarker) -> UIView?

您必须继承GSMarker的子类，后者会将模型放入init中。

class MapItem:GMSMarker {
    var model: Model!  //your data model
    init(data: Model) {
        super.init()
        // pass cordinate
        self.position = CLLocationCoordinate2D(latitude: data.latitude!, longitude: data.longitude!) 
        // pass Model
        self.model = data 
    }
}

func mapView(_ mapView: GMSMapView, markerInfoWindow marker: GMSMarker) -> UIView? {
    // Wrap GSMarker to your custom marker which is MapItem here
    let customMarker = marker as! MapItem 
      // pass your model to CustomView(marker info window) in init 
    let customView = CustomView(markerModel: customMarker.model)
    return customView
}
