My goal is to parse lat and long to the google maps, assume that mapView is the view object of GMSMapView class and I have initialized it.
override func viewDidLoad() {
super.viewDidLoad()
locationManager.delegate = self
// Ask for Authorisation from the User.
self.locationManager.requestAlwaysAuthorization()
// For use in foreground
self.locationManager.requestWhenInUseAuthorization()
// This is where I will parse the lat and long
var coordinate: CLLocationCoordinate2D
coordinate = CLLocationCoordinate2D(latitude: 3.203119, longitude: 101.7276145)
mapView.projection.containsCoordinate(coordinate)
}
Whenever I run it, it doesn't show the marker of the custom coordinates
let camera = GMSCameraPosition.cameraWithLatitude(yourLatitude,
longitude: yourLongitude, zoom: 15)
mapView = GMSMapView.mapWithFrame(CGRectZero, camera: camera)
mapView.myLocationEnabled = true
mapView.delegate = self
mapView.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)
self.view.addSubview(mapView)
let marker = GMSMarker()
marker.position = CLLocationCoordinate2DMake(yourLatitude, yourLongitude)
marker.title = strTitleOfMarker
marker.snippet = strSubTitleOfMarker
marker.map = mapView
// Add this to .plist file
<key>NSLocationAlwaysUsageDescription</key>
<string>Access your location</string>

I have followed GoogleMaps SDK. The map shows well. MyLocation, zoom-in, zoom-out all work well.
The issue is when I click "myLocation" button after zoom-in or zoom-out and move to other location, the map will go back to my location, BUT the zoom stays as zoom-in or zoom-out level. It doesn't get back to original zoom level. My code is as follow:
//googleMap
var locationManager = CLLocationManager()
var currentLocation: CLLocation?
var mapView: GMSMapView!
var placesClient: GMSPlacesClient!
var zoomLevel: Float = 15.0
// An array to hold the list of likely places.
var likelyPlaces: [GMSPlace] = []
// The currently selected place.
var selectedPlace: GMSPlace?
override func viewDidLoad() {
super.viewDidLoad()
locationManager = CLLocationManager()
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
locationManager.distanceFilter = 50
locationManager.startUpdatingLocation()
locationManager.delegate = self
let camera = GMSCameraPosition.camera(withLatitude: 43.6532,
longitude: 79.3832,
zoom: zoomLevel)
mapView = GMSMapView.map(withFrame: view.bounds, camera: camera)
mapView.settings.myLocationButton = true
mapView.settings.compassButton = true
mapView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
mapView.isMyLocationEnabled = true
// Add the map to the view, hide it until we've got a location update.
view.addSubview(mapView)
mapView.isHidden = true
placesClient = GMSPlacesClient.shared()
}
In my CLLocationManagerDelegate I have:
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let location: CLLocation = locations.last!
print("Location: \(location)")
let camera = GMSCameraPosition.camera(withLatitude: location.coordinate.latitude,
longitude: location.coordinate.longitude,
zoom: zoomLevel)
mapView.camera = GMSCameraPosition.camera(withLatitude: location.coordinate.latitude,
longitude: location.coordinate.longitude,
zoom: zoomLevel)
if mapView.isHidden {
mapView.isHidden = false
mapView.camera = camera
} else {
mapView.animate(to: camera)
}
}
I am using google maps in ios with swift 4, i have to show a mapview in the screen, with a marker, the problem is that whenever i show the mapview i got this result:
and the result i want to get is this:
here is the code i am using:
func loadMap(location:CLLocation){
self.mapView.isMyLocationEnabled = true
self.mapView.isUserInteractionEnabled = true
self.view.layoutIfNeeded()
self.addLocationMarker()
}
func addLocationMarker(){
// Creates a marker in the center of the map.
let marker = GMSMarker()
print(self.startLocation)
marker.position = CLLocationCoordinate2D(latitude: self.startLocation.coordinate.latitude, longitude: self.startLocation.coordinate.longitude)
marker.map = self.mapView
let camera = GMSCameraPosition.camera(withLatitude: self.startLocation.coordinate.latitude, longitude: self.startLocation.coordinate.longitude, zoom: 12.0)
self.mapView.camera = camera
}
and the mapview is an outlet of a view in the storyboard
This Code works fine for me. Try this out (Swift 4)
func setupMapView() {
DispatchQueue.main.async {
let position = CLLocationCoordinate2D(latitude: 32.9483364, longitude: -96.8241543)
let marker = GMSMarker(position: position)
self.mapView.camera = GMSCameraPosition(target: position, zoom: 15, bearing: 0, viewingAngle: 0)
marker.title = "Enter marker title here"
marker.map = self.mapView
}
}
Note: I have used sample longitude and lattitude. You should insert your's.
import UIKit

// sets the info in the custom info window
func mapView(_ mapView: GMSMapView, didTap marker: GMSMarker) -> Bool {
if(currentMarker == marker && showing) {

showing = false
} else {
infoWindow.isHidden = false
self.view.addSubview(infoWindow)
self.view.bringSubview(toFront: infoWindow)

return true
}
#IBAction func myLocationTapped(_ sender: Any) {
print("tapped")
let cameraPosition = GMSCameraPosition.camera(withLatitude: place.latitude, longitude: place.longitude, zoom: 15.0)
mapView.animate(to: cameraPosition)
}
I have the following code set up, designed to place a button on the google maps map that when tapped, animates the google maps camera to that location. However, my code doesn't work. The "tapped" prints in the console but the camera doesn't budge. I haven't been able to find an answer anywhere for this, so any help would be appreciated.
EDIT: Added full code for the Map View Controller
In my case the map wasn't updating because I was not calling the method on the main queue. The following code solved the issue:
DispatchQueue.main.async {
self.mapView.animate(to: camera)
}
Anything action related to the user interface should be called in the main queue
Try this way
let cameraPosition = GMSCameraPosition.camera(withLatitude: place.latitude, longitude: place.longitude, zoom: 15.0)
mapView.animate(to: cameraPosition)
Edit: Issue is you aren't having the reference of your map with your mapView object, change your viewDidLoad's line:
view = mapView
TO:
// sets up the map view (camera, location tracker etc.)
let camera = GMSCameraPosition.camera(withLatitude: place.latitude, longitude: place.longitude, zoom: 17.0)
let mapView = GMSMapView.map(withFrame: view.bounds, camera: camera)
mapView.isMyLocationEnabled = true
mapView.delegate = self
self.mapView = mapView
view.addSubview(self.mapView)
This is the current code, after making the edits suggested, it no longer shows a marker on the map for Sydney Australia
class LocateVC: UIViewController {
#IBOutlet weak var mapView: GMSMapView!
override func viewDidLoad() {
super.viewDidLoad()
//override func loadView() {
// Create a GMSCameraPosition that tells the map to display the
// coordinate -33.86,151.20 at zoom level 6.
let camera = GMSCameraPosition.camera(withLatitude: -33.86 , longitude: 151.20, zoom: 6.0)
let mapView = GMSMapView.map(withFrame: self.mapView.bounds, camera: camera)
self.mapView = mapView
// Creates a marker in the center of the map.
let marker = GMSMarker()
marker.position = CLLocationCoordinate2D(latitude: -33.86, longitude: 151.20)
marker.title = "Sydney"
marker.snippet = "Australia"
marker.map = mapView
}
}
Output
This is the screen that loads
And no marker on Sydney Australia
Your are setting mapview to main view of ViewController
So Change your these two lines
let mapView = GMSMapView.map(withFrame: CGRect.zero, camera: camera)
view = mapView
With:
let mapView = GMSMapView.map(withFrame: self.mapView.bounds, camera: camera)
self.mapView = mapView
The answer from #Nirav is almost there
here what I did:
import UIKit
import GoogleMaps
class AddressMapController: UIViewController {
#IBOutlet weak var map123: GMSMapView! // this is linked to a UIView in storyboard
var currentLocation: CLLocation! //this is passed from the main controller
override func viewDidLoad() {
super.viewDidLoad()
let lat = currentLocation.coordinate.latitude
let long = currentLocation.coordinate.longitude
let camera = GMSCameraPosition.camera(withLatitude: lat , longitude: long, zoom: 12)
// Creates a marker in the center of the map.
let currentLocation_Marker = GMSMarker()
currentLocation_Marker.position = CLLocationCoordinate2D(latitude: lat, longitude: long)
currentLocation_Marker.title = "My Current Location"
currentLocation_Marker.snippet = "I am here now"
currentLocation_Marker.map = map123
self.map123.camera = camera
}
}
hope it will help somebody in the future
Hello i was trying to put map in subview but when i put google map in sub view it doesn't work marker and GPS Coordinates don't work
-With Sub View
-Without Sub View
-SWIFT CODE
import UIKit
import GoogleMaps
class HomeViewController: UIViewController, CLLocationManagerDelegate {
#IBOutlet weak var mapView: GMSMapView!
let locationManager = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
locationManager.delegate = self
locationManager.requestAlwaysAuthorization()
let camera = GMSCameraPosition.cameraWithLatitude(15.4989, longitude: 73.8278, zoom: 6)
let mapView = GMSMapView.mapWithFrame(CGRectZero, camera: camera)
mapView.myLocationEnabled = true
// self.view = mapView
self.view.addSubview(mapView)
let marker = GMSMarker()
marker.position = CLLocationCoordinate2DMake(15.4989, 73.8278)
marker.title = "Panjim"
marker.snippet = "Near Don Bosco,Alphran Plaza"
marker.map?.addSubview(mapView)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
Thanks in advance
I found the solution. The problem was : i was creating a new map, then was adding a marker to that new map. Then with the new map i was doing nothing.
So here is my Solution :
#IBOutlet weak var subviewMap: GMSMapView!
func loadMap() {
let camera = GMSCameraPosition.camera(withLatitude: -33.86, longitude: 151.20, zoom: 10.0)
subviewMap.camera = camera
let marker = GMSMarker()
marker.position = CLLocationCoordinate2D(latitude: -33.86, longitude: 151.20)
marker.title = "Sydney"
marker.snippet = "Australia"
marker.map = subviewMap
}
And it works.
NOTE : Do not forget to Mention your subview as GMSMapView class in IB
Thanks #O-mkar and #mixth for efforts.
Happy Coding :]
Here is the solution to add marker
let marker = GMSMarker()
marker.position = CLLocationCoordinate2DMake(lat, long)
marker.appearAnimation = kGMSMarkerAnimationPop
marker.title = "Marker" // Marker title here
marker.snippet = "Tap the ↱ Navigate button to start navigating."
marker.infoWindowAnchor = CGPoint(x: 0.5, y: 0)
marker.icon = UIImage(named: "marker") //Set marker icon here
marker.map = self.mapView // Mapview here
Animate Camera to position
let camera = GMSCameraPosition.camera(withLatitude: 15.4989, longitude: 73.8278, zoom: 17)
mapView.animate(to: camera)
I have my GMSMapView inside another UIView and everything just works fine. The only different line is:
marker.map = mapView
after adding marker you should add some delay with this approach i have added 2 marker with bounds
DispatchQueue.main.async {
if self.markerArray.count > 1 {
var bounds = GMSCoordinateBounds()
for marker in self.markerArray {
marker.map = self.mapView
bounds = bounds.includingCoordinate(marker.position)
}
self.isMovedTheMap = false
DispatchQueue.main.asyncAfter(deadline: .now() + 0.9, execute: {
self.superTopView.fadeOut()
let update = GMSCameraUpdate.fit(bounds, withPadding: 80)
self.mapView.animate(with: update)
})
}
}
