如何在不点击标记的情况下在 iOS 谷歌地图中显示信息窗口？

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.

GMSMarkerOption *myLocationOption = [GMSMarkerOption alloc];
myLocationOption .title = @"My Location";
myLocationOption .snippet = @"Lat:...., Lang:....";

[mapView addMarkerOption:myLocationOption];

As per the above code, Marker displayed in the Map View as expected. And tapping on marker shows the "My Location" info window in Google maps which is good.

Is there anyway we can show the info window programmatically when the user goes to Custom Map Screen?

Answer 1

This has changed on Google Maps SDK and it's easier to understand:

GMSMarker *marker = [[GMSMarker alloc] init];
marker.position = coordinate;
marker.title = @"Location selected";
marker.snippet = @"Testing";
marker.map = mapView_;

//Show info window on map
[mapView_ setSelectedMarker:marker];

You use now setSelectedMarker method to show an info window of a marker

Answer 2

GMSMarkerOptions *myLocationOptions = [GMSMarkerOptions options];
myLocationOptions.title = @"My Location";
myLocationOptions.snippet = @"Lat:...., Lang:....";

mapView.selectedMarker = [mapView addMarkerWithOptions:myLocationOptions];

(note that it's Options, not Option)

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

Answer 4

swift 3

self.mapView.selectedMarker = marker

In the case of swift 3, you can open the snipet usint the selectedMarker

If you are creating the marker in a similar way to:

marker.position = CLLocationCoordinate2D(latitude: 34.1331168, longitude: -118.3550723)
marker.title = "My super place name"
marker.snippet = "Are you looking a place to play? This is your place! "
marker.appearAnimation = kGMSMarkerAnimationPop
marker.map = self.mapView

Answer 5

   // Below line will shows the infowindow for marker with out tapping on it
   [mapView setSelectedMarker:myLocationOptions]; // myLocationOptions is your desired GMSMarker to show Infowindow with out tapping .

Happy Coding :)

Answer 6

mMapView.selectedMarker =标记

Answer 7

--> It shows multiple infoWindows without tapping on marker. You can easily customise it.

for i in 0..

        let dict = arrNearByPlacesArray.object(at: i) as? NSDictionary ?? [:]

        let lat = dict.object(forKey: "latitude") as? String ?? ""
         let long = dict.object(forKey: "longitude") as? String ?? ""
        let company_id = dict.object(forKey: "company_id") as? String ?? ""
        let totaljobs = dict.object(forKey: "totaljobs") as? String ?? ""


        let location = CLLocationCoordinate2D(latitude: Double(lat) ?? 0.0, longitude: Double(long) ?? 0.0)
        print("location: \(location)")
        let marker = GMSMarker()
        //marker.icon = UIImage(named: "maps")

        let viewData = Bundle.main.loadNibNamed("MarkerXibView", owner: self, options: nil)?.first as! MarkerXibView .      //UIView


        marker.iconView = viewData .      //UIView


        marker.position = location
        marker.accessibilityLabel  = company_id
        marker.map = vwGoogleMap

}

Answer 8

GMSMarkerOptions is deprecated. Using this helped me to show info window without tapping-

func mapView(_ mapView: GMSMapView, idleAt position: GMSCameraPosition) {
    myMapView.selectedMarker = myGMSMarker
}
