How to show a Info window in iOS Google maps without tapping on Marker?

Question

I am new to iOS development. This is regarding Marker info window in Google Maps iOS SDK.

I understand, we can create a marker with info window using GMSMarkerOption

Answer 1

mMapView.selectedMarker = marker

Answer 2

Swift 3.0

func addMarker(_ location:CLLocation){
        var locationMarker: GMSMarker!
        if locationMarker != nil {
            locationMarker.map = nil
        }
        locationMarker = GMSMarker(position: location.coordinate)
        locationMarker.map = mapView
        locationMarker.appearAnimation = kGMSMarkerAnimationPop
        locationMarker.icon = GMSMarker.markerImage(with: UIColor.green)
        locationMarker.opacity = 0.85
        locationMarker.isFlat = true
        locationMarker.snippet = "My Location"
        mapView.selectedMarker=locationMarker

    }

below line is the answer

mapView.selectedMarker=locationMarker
