I'm trying to change GMSMarker icon with Moa but marker is still showing default icon. This is my code:
override func viewDidLoad() {
super.viewDidLoad()
locationmanager.delegate = self
let authorizationStatus = CLLocationManager.authorizationStatus()
if(authorizationStatus == .authorizedWhenInUse || authorizationStatus == .authorizedAlways) {
locationmanager.startUpdatingLocation()
MapView.isMyLocationEnabled = true
MapView.settings.myLocationButton = true
} else {
locationmanager.requestWhenInUseAuthorization()
}
MapView.camera = GMSCameraPosition.camera(withLatitude: 32.4279, longitude: 53.6880, zoom: 5)
MapView.delegate = self
prepareMapMarkers()
}
func prepareMapMarkers(){
let marker = GMSMarker(position: CLLocationCoordinate2D(latitude: CLLocationDegrees(malls[0].lat), longitude: CLLocationDegrees(malls[0].long)))
marker.map = MapView
moa.onSuccess = { image in
print(image)
marker.icon = image.images?[0]
return image
}
moa.url = "http://www.w3schools.com/css/img_fjords.jpg"
}
console
<UIImage: 0x60000009e050>, {600, 400}
That image is just for test. Why it's not working?
Try this! It worked for me
let pin = UIImage(named: "maps_icon_location")!.imageWithRenderingMode(.AlwaysTemplate)
marker.icon = pin
You are attempting to change the image of a marker after it is added. I am not sure if Google Maps SDK supports this, but it is not a good idea. Instead, download you photo, then create the marker and add it to the map:
moa.onSuccess = { image in
let marker = GMSMarker(position: CLLocationCoordinate2D(latitude: CLLocationDegrees(malls[0].lat), longitude: CLLocationDegrees(malls[0].long)))
marker.icon = image.images?[0]
marker.map = self.MapView
}
moa.url = "http://www.w3schools.com/css/img_fjords.jpg"

I am building an application where I have to move multiple marker. These markers will be visible at my end according to the multiple user's live locations. I am able to update only a single marker. but the rest are not updating. I stored these data in firebase and I am getting their data from there.

I am building an ios application that uses a google map to display the location of the places return in the server. I manage to display the result in the initial load of the map, but when I want to search new plaaces and reload the markers in the map. Unfortunately the app was crashes.
Hope for your help.
Thank you.
Here is my code in the ViewController to initially display the markers:
func setUpMap() {
let camera = GMSCameraPosition.camera(withLatitude: -33.86, longitude: 151.20, zoom: 10.0)
self.mapView.camera = camera
let map_view = GMSMapView.map(withFrame: CGRect.zero, camera: camera)
for data in arrData {
let long = data["LONGITUDE"].string!
let lat = data["LATITUDE"].string!
if long != "" || lat != "" {
let marker = GMSMarker()
marker.position = CLLocationCoordinate2D(latitude: CLLocationDegrees(lat)!, longitude: CLLocationDegrees(long)!)
marker.title = ""
marker.snippet = "Hey, this is sample"
marker.icon = UIImage(named: "locator")
marker.map = self.mapView
bounds = bounds.includingCoordinate(marker.position)
}
}
// fit to bounds
mapView.animate(with: GMSCameraUpdate.fit(bounds, withPadding: 50.0))
self.mapView = map_view
}
Here is my code to reload/reset the markers in the map.
func reloadMarkers() {
self.mapView.clear()
let camera = GMSCameraPosition.camera(withLatitude: -33.86, longitude: 151.20, zoom: 10.0)
self.mapView.camera = camera
let map_view = GMSMapView.map(withFrame: CGRect.zero, camera: camera)
var _bounds = GMSCoordinateBounds()
for data in arrData {
let long = data["LONGITUDE"].string!
let lat = data["LATITUDE"].string!
if long != "" || lat != "" {
let marker = GMSMarker()
marker.position = CLLocationCoordinate2D(latitude: CLLocationDegrees(lat)!, longitude: CLLocationDegrees(long)!)
marker.title = ""
marker.snippet = "Hey, this is sample"
marker.icon = UIImage(named: "locator")
marker.map = self.mapView
_bounds = _bounds.includingCoordinate(marker.position)
}
}
// fit to bounds
mapView.animate(with: GMSCameraUpdate.fit(bounds, withPadding: 50.0))
self.mapView = map_view
}
Thanks for the help.
Cheers!
I found a solution, please see sample code below.
func reloadMarkers() {
let camera = GMSCameraPosition.camera(withLatitude: 12.0377995, longitude: 122.6408281, zoom: 10.0)
let map_view = GMSMapView.map(withFrame: self.brachMapView.bounds, camera: camera)
map_view.camera = camera
var bounds = GMSCoordinateBounds()
for data in arrData {
let long = data["LONGITUDE"].string!
let lat = data["LATITUDE"].string!
if long != "" || lat != "" {
let marker = GMSMarker()
marker.position = CLLocationCoordinate2D(latitude: CLLocationDegrees(lat)!, longitude: CLLocationDegrees(long)!)
marker.title = ""
marker.snippet = "Hey, this is sample"
marker.icon = UIImage(named: "locator")
marker.map = map_view
bounds = bounds.includingCoordinate(marker.position)
}
}
// fit to bounds
map_view.animate(with: GMSCameraUpdate.fit(bounds, withPadding: 50.0))
self.brachMapView.addSubview(map_view)
}
Thanks.

I have to plot multiple pins in a Google Map view, and then zoom to the user's current location. Pins are plotted successfully but not zoomed to current location. Any help would be appreciated
override func viewDidAppear(_ animated: Bool) {
if (self.googleMapsView == nil) {
self.googleMapsView = GMSMapView(frame: self.mapViewContainer.frame)
self.view.addSubview(self.googleMapsView)
print(AppDelegate.getAppDelegate().mapArray)
googleMapsView.clear()
for i in 0...AppDelegate.getAppDelegate().mapArray.count - 1 {
let lon = Double ((AppDelegate.getAppDelegate().mapArray[i]["lon"] as? String)!)
let lat = Double ((AppDelegate.getAppDelegate().mapArray[i]["lat"] as? String)!)
let tit = AppDelegate.getAppDelegate().mapArray[i]["location"] as? String
locateWithLongitude(lon: lon!,andLatitude: lat! ,andTitle: tit!)
}
let marker = GMSMarker(position: AppDelegate.getAppDelegate().myLocation)
let camera = GMSCameraPosition.camera(withLatitude: AppDelegate.getAppDelegate().myLocation.latitude, longitude: AppDelegate.getAppDelegate().myLocation.longitude, zoom: 11)
self.googleMapsView.camera = camera
marker.title = AppDelegate.getAppDelegate().sublocality
marker.map = self.googleMapsView
self.googleMapsView.animate(to: camera)
}
}
func locateWithLongitude(lon: Double, andLatitude lat: Double, andTitle title: String) {
DispatchQueue.main.async() { () -> Void in
let position = CLLocationCoordinate2DMake(lat, lon)
let marker = GMSMarker(position: position)
let camera = GMSCameraPosition.camera(withLatitude: lat, longitude: lon, zoom: 0)
self.googleMapsView.camera = camera
marker.title = title
marker.map = self.googleMapsView
}
}
Your zoom is set to 0, increase it to 15/16 like bellow.
let camera = GMSCameraPosition.camera(withLatitude: lat, longitude: lon, zoom: 16)
I'm using google maps to track
func ShowcurrentMarker()
{
currentlocationCoordinate = CLLocationCoordinate2DMake(LatestLocation.coordinate.latitude, LatestLocation.coordinate.longitude)
if(CurrentLocationMarker == nil)
{
CurrentLocationMarker = GMSMarker(position:currentlocationCoordinate)
CurrentLocationMarker.map = self.mapView
CurrentLocationMarker.icon = UIImage.init(named:"car_icon")
mapView.camera = GMSCameraPosition.camera(withTarget: CLLocationCoordinate2DMake(LatestLocation.coordinate.latitude, LatestLocation.coordinate.longitude), zoom: 15.0)
}
else
{
CATransaction.begin()
CATransaction.setAnimationDuration(2)
CurrentLocationMarker.position = currentlocationCoordinate
CurrentLocationMarker.rotation = CLLocationDirection.abs(LatestLocation.course)
mapView.camera = GMSCameraPosition.camera(withTarget: CLLocationCoordinate2DMake(LatestLocation.coordinate.latitude, LatestLocation.coordinate.longitude), zoom:mapView.camera.zoom)
CATransaction.commit()
}
}
Here is my working code. Now I want my car always to keep on north facing like navigation app.
How can I do that ?
this is my code and I want to change location arrow icon (blue dot). how I can do it in swift code. I'm using google maps! I attached photo which is I want to do it.
func moveCamera(marker:GMSMarker){
map.camera = GMSCameraPosition(target: marker.position, zoom: 12, bearing: 0, viewingAngle: 0)
}
func placeMarkersInMap(){
var marker:GMSMarker = GMSMarker()
if(addressArray.count > 0){
for add in addressArray{
let position = CLLocationCoordinate2DMake(add.longitud, add.latitude)
marker = GMSMarker(position: position)
marker.appearAnimation = kGMSMarkerAnimationPop
marker.icon = UIImage(named: "marker")
marker.title = add.location
marker.snippet = "\nTel. \(add.tel)"
marker.infoWindowAnchor = CGPointMake(0.44, 0.45)
marker.map = map
}
moveCamera(marker)
}
}
func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
if status == .AuthorizedWhenInUse {
locationManager.startUpdatingLocation()
map.myLocationEnabled = true
map.settings.myLocationButton = true
}
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
if let location = locations.first {
locationManager.stopUpdatingLocation()
}
}
let position = CLLocationCoordinate2DMake(// here will be your coords)
let london = GMSMarker(position: position)
london.title = "London"
london.icon = UIImage(named: "here will be your image name")
london.map = mapView;
