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;

I am trying to show three things on map :
GPS (the current location) , Marker 1 , Marker 2, but I am not sure I am doing it right or not ! Here is my code :
self.startMarker.position = CLLocationCoordinate2D(latitude: self.startLatitude, longitude: self.startLongitude)
self.startMarker.icon = #imageLiteral(resourceName: "Pin Start")
self.startMarker.map = self.mapView
self.endMarker.position = CLLocationCoordinate2D(latitude: self.endLatitude, longitude: self.endLongitude)
self.endMarker.icon = #imageLiteral(resourceName: "Pin End")
self.endMarker.map = self.mapView
let southWest = CLLocationCoordinate2DMake(self.startLatitude,self.startLongitude)
let northEast = CLLocationCoordinate2DMake(self.endLatitude,self.endLongitude)
let bounds = GMSCoordinateBounds(coordinate: northEast, coordinate: southWest)
let camera = self.mapView.camera(for: bounds, insets:.zero)
self.mapView.camera = camera!
More Code :
// MARK: - Google Map
private func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
if status == CLAuthorizationStatus.authorizedWhenInUse {
mapView.isMyLocationEnabled = true
}
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let newLocation = locations.last
mapView.camera = GMSCameraPosition.camera(withTarget: newLocation!.coordinate, zoom: 14)
mapView.isMyLocationEnabled = true
}
The result is like this :
What I need :
EDITED
if let myLocation = self.mapView.myLocation {
let path = GMSMutablePath()
path.add(myLocation.coordinate)
path.add(self.startMarker.position)
path.add(self.endMarker.position)
let bounds = GMSCoordinateBounds(path: path)
self.mapView.animate(with: GMSCameraUpdate.fit(bounds, withPadding: 40))
}
Showing All Markers with screen bound:
Here I am trying to provide you one simple example, hope this will help you.
Using this, you can show any number of markers on screen.
Example:
let path = GMSMutablePath()
for var i in 0 ..< array.count //Here take your "array" which contains lat and long.
{
let marker = GMSMarker()
let lat = Double(array.objectAtIndex(i).valueForKey(lattitude) as! String)
let long = Double(arrayr.objectAtIndex(i).valueForKey(longitude) as! String)
marker.position = CLLocationCoordinate2DMake(lat!,long!)
path.addCoordinate(marker.position)
marker.map = self.mapView
}
let bounds = GMSCoordinateBounds(path: path)
self.mapView!.animateWithCameraUpdate(GMSCameraUpdate.fitBounds(bounds, withPadding: 30.0))
Can you try the below code, this is converted from ObjC code here is the documentation of includingCoordinate
let bounds = GMSCoordinateBounds()
bounds.includingCoordinate(self.startMarker.position)
bounds.includingCoordinate(self.endMarker.position)
bounds.includingCoordinate(yourCurrentLocationPosition)
self.mapView.animateWithCameraUpdate(GMSCameraUpdate(fitBounds:bounds, padding:20.0f))
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
showMarkers(locations)
//stop updating location when you find suitable
}
func showMarkers(userLocation: [CLLocation]){
let location1: CLLocationCoordinate2D = CLLocationCoordinate2D(latitude: self.startLatitude, longitude: self.startLongitude)
let location2: CLLocationCoordinate2D = CLLocationCoordinate2D(latitude: self.endLatitude, longitude: self.endLongitude)
let location3: CLLocationCoordinate2D = userLocation[0].coordinate
var locationArray = []
locationArray.append(location1)
locationArray.append(location2)
locationArray.append(location3)
var bounds = GMSCoordinateBounds()
for location in locationArray
{
let latitude = location.valueForKey("latitude")
let longitude = location.valueForKey("longitude")
let marker = GMSMarker()
marker.position = CLLocationCoordinate2D(latitude: latitude, longitude: longitude)
marker.map = self.mapView
bounds = bounds.includingCoordinate(marker.position)
}
let update = GMSCameraUpdate.fitBounds(bounds, withPadding: 100)
mapView.animateWithCameraUpdate(update)
}
Note:
locationArray contains three locations ie. Marker 1, Marker 2, user location.
For someone who is looking for solution with Objective-C, This might help
//Locations
CLLocationCoordinate2D source = CLLocationCoordinate2DMake(19.2880, 72.1587);
CLLocationCoordinate2D userLocation = CLLocationCoordinate2DMake(19.1780, 72.9577);
CLLocationCoordinate2D destination = CLLocationCoordinate2DMake(19.0760, 72.8777);
//Create a GMSMutablePath
GMSMutablePath *path = [GMSMutablePath new];
[path addCoordinate:source];
[path addCoordinate:userLocation];
[path addCoordinate:destination];
//Create bounds
GMSCoordinateBounds *bounds = [[GMSCoordinateBounds alloc]initWithPath:path];
//Update the camera position
[mapview animateWithCameraUpdate:[GMSCameraUpdate fitBounds:bounds]];
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'm creating a sort of direction/GPS app and so far everything has been sort of easy.
I've figured out how to find the user's location (with their permission of course)
I've managed to allow them to set a destination in a quick easy way
However, I've run into a small issue. What I want is for the user to select their destination on the screen and the app will give them the fastest way to arrive there.
Here's my ViewController:
class ViewController: UIViewController,MKMapViewDelegate,CLLocationManagerDelegate {
#IBOutlet var mapOfMaps: MKMapView!
let locationManager = CLLocationManager()
var center:CLLocationCoordinate2D!
var SourcePM:MKPlacemark!
let sourcePlacemark: MKPlacemark! = nil
override func viewDidLoad() {
super.viewDidLoad()
self.locationManager.delegate = self
self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
self.locationManager.requestWhenInUseAuthorization()
self.locationManager.startUpdatingLocation()
self.mapOfMaps.showsUserLocation = true
let sourceAnnotation = MKPointAnnotation()
if let location = locationManager.location {
sourceAnnotation.coordinate = location.coordinate
}
let longPress = UILongPressGestureRecognizer(target: self, action: #selector(CardioViewController.action(_:)))
longPress.minimumPressDuration = 1.0
mapOfMaps.addGestureRecognizer(longPress)
//directionRequest
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let location = locations.last
center = CLLocationCoordinate2D(latitude: location!.coordinate.latitude, longitude: location!.coordinate.longitude)
let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.003, longitudeDelta: 0.003))
self.mapOfMaps.setRegion(region, animated: true)
self.locationManager.stopUpdatingLocation()
SourcePM = MKPlacemark(coordinate: center, addressDictionary: nil)
}
func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
print("ERROr " + error.localizedDescription)
}
func action(gestureRecognizer:UIGestureRecognizer) {
let touchPoint = gestureRecognizer.locationInView(self.mapOfMaps)
let newCoord:CLLocationCoordinate2D = mapOfMaps.convertPoint(touchPoint, toCoordinateFromView: self.mapOfMaps)
let newAnotation = MKPointAnnotation()
newAnotation.coordinate = newCoord
newAnotation.title = "Your Destination"
mapOfMaps.addAnnotation(newAnotation)
let anotPM = MKPlacemark(coordinate: newAnotation.coordinate, addressDictionary: nil)
let source = MKMapItem(placemark: SourcePM)
let dstn = MKMapItem(placemark: anotPM)
let directionRequest = MKDirectionsRequest()
directionRequest.source = source
directionRequest.destination = dstn
directionRequest.transportType = .Automobile
// Calculate the direction
let directions = MKDirections(request: directionRequest)
// 8.
directions.calculateDirectionsWithCompletionHandler() {
(response, error) in
if(error == nil && response != nil) {
for route in response!.routes {
var r: MKRoute = route as! MKRoute
self.mapOfMaps.addOverlay(r.polyline, level: MKOverlayLevel.AboveRoads)
}
}
let route = response!.routes[0]
self.mapOfMaps.addOverlay((route.polyline), level: MKOverlayLevel.AboveLabels)
let rect = route.polyline.boundingMapRect
self.mapOfMaps.setRegion(MKCoordinateRegionForMapRect(rect), animated: true)
}
}
func mapView(mapView: MKMapView, rendererForOverlay overlay: MKOverlay) -> MKOverlayRenderer {
let renderer = MKPolylineRenderer(overlay: overlay)
renderer.strokeColor = UIColor.orangeColor()
renderer.alpha = 1
renderer.lineWidth = 4.0
return renderer
}
}
to help walk you through my code. My user will press and hold the destination on the map and the app will add an annotation and it should give the route. However, all that happens is the annotation will be added to the map, and the map will adjust to show both locations(user's location and annotation location) but no route.
This may not be the 'ideal' solution, but it's worth noting that both locationManager functions can't work at the same time. I tried commenting one of the locationManager functions out and low and behold the other worked perfectly
I am new to Swift and I need to calculate the nearest places around my current location. Would you advice me which function should I use to calculate the distance between my location and the nearest around me. I have to display the distance and the places in the app,so that the user can choose which one fits best for him.I think I should use latitude and longitude coordinates which can be compared with mine. I also found out that I have to use distanceFromLocation , but I do not know how and I would be glad if someone provide me with an example which I can use for my code.
My code so far is:
class ViewThree: UIViewController, CLLocationManagerDelegate{
#IBOutlet weak var SegmentControl: UISegmentedControl!
#IBOutlet weak var Mapview: MKMapView!
var manager = CLLocationManager()
var receiveImeNaSladkarnica: String = ""
var KordaA: String = ""
var KordaB: String = ""
var PodImeNaObekt: String = ""
override func viewDidLoad() {
super.viewDidLoad()
let pinLocation: CLLocationCoordinate2D = CLLocationCoordinate2DMake((KordaA as NSString).doubleValue,(KordaB as NSString).doubleValue)
let objectAnn = MKPointAnnotation()
objectAnn.coordinate = pinLocation
objectAnn.title = receiveImeNaSladkarnica
objectAnn.subtitle = PodImeNaObekt
self.Mapview.addAnnotation(objectAnn)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
#IBAction func Directions(sender: AnyObject) {
UIApplication.sharedApplication().openURL(NSURL(string: "http://maps.apple.com/maps?daddr=\((KordaA as NSString).doubleValue),\((KordaB as NSString).doubleValue))")!)
}
#IBAction func MapType(sender: AnyObject) {
if (SegmentControl.selectedSegmentIndex == 0){
Mapview.mapType = MKMapType.Standard
}
if (SegmentControl.selectedSegmentIndex == 1){
Mapview.mapType = MKMapType.Satellite
}
}
#IBAction func LocateMe(sender: AnyObject) {
manager.delegate = self
manager.desiredAccuracy = kCLLocationAccuracyBest
manager.requestWhenInUseAuthorization()
manager.startUpdatingLocation()
Mapview.showsUserLocation = true
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let userlocation: CLLocation = locations[0] as CLLocation
manager.stopUpdatingLocation()
let location = CLLocationCoordinate2D(latitude: userlocation.coordinate.latitude, longitude: userlocation.coordinate.longitude)
let span = MKCoordinateSpanMake(0.5, 0.5)
let region = MKCoordinateRegion(center: location, span: span)
Mapview.setRegion(region, animated: true )
}
I had the same scenario with an other app.
Within the CLLocation object, there is an instance function:
func distanceFromLocation(location: CLLocation) -> CLLocationDistance
//Get your two locations that you want to calculate the distance from:
let userLocation: CLLocation = ...
let locationToCompare: CLLocation = ...
// Returned value is in meters
let distanceMeters = userLocation.distanceFromLocation(locationToCompare)
// If you want to round it to kilometers
let distanceKilometers = distanceMeters / 1000.00
// Display it in kilometers
let roundedDistanceKilometers = String(Double(round(100 * distanceKilometers) / 100)) + " km"
UPDATED
For your use case
let locations = ... // All locations you want to compare
for location in locations {
let distanceMeters = userLocation.distanceFromLocation(location)
if distanceMeters > 5000 { // Some distance filter
// Don't display this location
} else {
// Display this location
}
}
MY CODE:
IMPROVED
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let userlocation:CLLocation = locations[0] as CLLocation
manager.stopUpdatingLocation()
let location = CLLocationCoordinate2D(latitude: userlocation.coordinate.latitude, longitude: userlocation.coordinate.longitude)
let span = MKCoordinateSpanMake(0.5, 0.5)
let region = MKCoordinateRegion(center: location, span: span)
Mapview.setRegion(region, animated: true)
let locationStrings = ["42.6977,23.3219","43.6977,24.3219"]
// This array must be an array that contains CLLocation objects
var locations: [CLLocation] = []
// We must retrieve the latitude and longitude from locationStrings array to convert them into CLLocation objects
for locationString in locationStrings {
let location = CLLocation(latitude: <latitude_value>, longitude: <latitude_value>)
locations.append(location)
}
// Then you will be able to enumerate through the array
for location in locations {
let distanceMeters = userLocation.distanceFromLocation(location)
if distanceMeters > 5000 { // Some distance filter
// Don't display this location
} else {
// Display this location
}
}
You can use distanceFromLocation method to get distance
let distance = userlocation.distanceFromLocation(YourPinInMap)
locA = [[CLLocation alloc] initWithLatitude:[[[NSUserDefaults standardUserDefaults]valueForKey:#"startLat"]floatValue] longitude:[[[NSUserDefaults standardUserDefaults]valueForKey:#"startlong"]floatValue]];
locB = [[CLLocation alloc] initWithLatitude:[[[NSUserDefaults standardUserDefaults]valueForKey:#"destLat"]floatValue] longitude:[[[NSUserDefaults standardUserDefaults]valueForKey:#"destLong"]floatValue]];
distance = [locA distanceFromLocation:locB];
where locA and locB are CLLocation type pass the lat long over there
I am building a learning app where i want to create pins and show the distance between current location and the pin but i get a really weird output
func createPin(){
var coord = CLLocationCoordinate2D(latitude: 51.50, longitude: -0.13)
var coord2 = CLLocation(latitude: coord.latitude, longitude: coord.longitude)
var kilometers:CLLocationDistance = coord2.distanceFromLocation(locNow)
var str = NSString(format: "%.2f", kilometers)
let pin = Annotation(coordinate: coord, title: "LocationAlfa", subtitle: "distance : \(str)" + " meters", dist: kilometers)
map.addAnnotation(pin)
println("\(kilometers)")
}
this is my create pin method and here i get my location distance
func locationManager(manager: CLLocationManager!, didUpdateToLocation newLocation: CLLocation!, fromLocation oldLocation: CLLocation!){
let location = newLocation
let center = CLLocationCoordinate2D(latitude: location!.coordinate.latitude, longitude: location!.coordinate.longitude)
var region: () = centerMapOnLocation(location)
// self.map.setRegion(region, animated: true)
println("Latitude = \(newLocation.coordinate.latitude)")
println("Longitude = \(newLocation.coordinate.longitude)")
locNow = newLocation
}
and this is the shown distance in meters on the map : 5718215.17 (when the pin is made next to the pointed location on the map as the device location)
