So I have been able to get the users location via the following code.
func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
if status != .authorizedWhenInUse {return}
print("test LOCATION BELOW")
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.startUpdatingLocation()
let locValue: CLLocationCoordinate2D = manager.location!.coordinate
print("UUID: \(String(describing: uuid)) locations = \(locValue.latitude) \(locValue.longitude)")
}
However I want to watch the users location and if they move update their location.
I am wondering how do I get this code to keep checking for the users location?
My
override func viewDidLoad(){
locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.requestWhenInUseAuthorization()
locationManager.requestAlwaysAuthorization()}
I get it popping up the request and I approve it but it does not run the code
Here is how you can get the location data. The code is similar to yours but with a bit of change and additions.
First check if you already have user's permission to get their location data.
func isLocationServicesEnabled() -> Bool {
if CLLocationManager.locationServicesEnabled() {
switch(CLLocationManager.authorizationStatus()) {
case .notDetermined, .restricted, .denied:
return false
case .authorizedAlways, .authorizedWhenInUse:
return true
#unknown default:
return false
}
}
return false
}
If this method returns false you can ask for authorization.
// Initialize manager in your viewDidLoad
override func viewDidLoad() {
super.viewDidLoad()
locationManager = CLLocationManager()
locationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters
locationManager.delegate = self
// Do other stuff
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
// Check for auth
if isLocationServicesEnabled() {
locationManager.startUpdatingLocation()
} else {
locationManager.requestWhenInUseAuthorization()
}
// Do other stuff
}
Finally in your CLLocationManagerDelegate implementation get the coordinates.
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
guard let location = locations.last?.coordinate else { return }
// Use location.latitude and location.longitude here
// If you don't want to receive any more location data then call
locationManager.stopUpdatingLocation()
}
First, you have to check that you have user's permission to get their location data
func checkLocationServicesAuthorization() -> Bool {
if CLLocationManager.locationServicesEnabled() {
switch CLLocationManager.authorizationStatus() {
case .notDetermined:
return false
case .restricted, .denied:
//code for open settings screen in user’s phone
return false
case .authorizedWhenInUse, .authorizedAlways:
return true
default:
return false
}
} else {
//code for open settings screen in user’s phone
}
return false
}
And
override func viewDidLoad() {
super.viewDidLoad()
locationManager = CLLocationManager()
locationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters
locationManager.delegate = self
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
if checkLocationServicesAuthorization() {
locationManager.startUpdatingLocation()
} else {
locationManager.requestWhenInUseAuthorization()
}
}
You can use delegate method didUpdateLocations of CLLocationManagerDelegate and don't forgot to connect delegate yourLocationManager.delegate = self
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let userLocation:CLLocation = locations[0] as CLLocation
// Call stopUpdatingLocation() to stop listening for location updates, other wise this function will be called every time when user location changes.
// yourLocationManager.stopUpdatingLocation()
guard let locValue: CLLocationCoordinate2D = manager.location?.coordinate else { return }
let latitude = String.init(userLocation.coordinate.latitude)
let longitude = String.init(userLocation.coordinate.longitude)
print("\(latitude), \(longitude)")
}
I am asking for requestWhenInUseAuthorization from CLLocationManager and the user prompt displays but then quickly disappears.
According to other posts on SO it says that you have to declare your CLLocationManager var at the class level to fix this.
Problem is that I am already doing this and this still happens.
Any help would be appreciated.
class myLocation: CLLocationManagerDelegate {
var locationManager:CLLocationManager?
// Have also tried it as: let locationManager = CLLocationManager()
func start() {
if CLLocationManager.locationServicesEnabled() {
self.locationManager = CLLocationManager()
guard let manager = self.locationManager else {
print("Error creating Location Manager")
return
}
manager.delegate = self
manager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
manager.requestWhenInUseAuthorization()
}
else {
print("Location Services Disabled")
}
}
//Delegate Methods
func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
switch status {
case .authorizedAlways, .authorizedWhenInUse:
manager.startUpdatingLocation()
default:
manager.requestWhenInUseAuthorization()
}
}
...
}
The key to fixing this was that the var I instantiated this class too was a local var. I moved that to a class var and it no longer disappears.
So for example:
class ViewController: UIViewController {
let location = myLocation.init()
override func viewDidLoad() {
super.viewDidLoad()
location.start()
}
}
I am building a location-based app that lists nearby coffee houses. App keeps crashing on first build on device because location keeps returning as nil.
This is because the Privacy - Location prompt isn't happening soon enough, even though though the request is earlier in the code. After I close the app after it crashes, that's when I'm prompted to allow my location.
I have three onboarding screens, and when I get to this tableviewcontroller, that's when it crashes.
If I go into Settings > Privacy > Location and manually enable location services, the app works great.
Here's my code (I removed a ton of unnecessary stuff):
import UIKit
import MapKit
import CoreLocation
class ShopTableViewController: UITableViewController, CLLocationManagerDelegate {
#IBAction func filterBack(_ sender: Any) {
getLocale()
shops.sort() { $0.distance < $1.distance }
shops.removeAll()
loadShops()
sortList()
}
//MARK: Properties
var shops = [CoffeeShop]()
var filteredShops = [CoffeeShop]()
var objects: [CoffeeShop] = []
var locationManager = CLLocationManager()
func checkLocationAuthorizationStatus() {
if CLLocationManager.authorizationStatus() == .authorizedWhenInUse {
locationManager.requestWhenInUseAuthorization()
}
}
var currentLocation = CLLocation!.self
var userLatitude:CLLocationDegrees! = 0
var userLongitude:CLLocationDegrees! = 0
var locValue:CLLocationCoordinate2D = CLLocationCoordinate2D(latitude: 1.0, longitude: 1.0)
var refresher: UIRefreshControl! = UIRefreshControl()
func getLocale() {
self.locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
self.locationManager.startMonitoringSignificantLocationChanges()
userLatitude = self.locationManager.location?.coordinate.latitude
userLongitude = self.locationManager.location?.coordinate.longitude
print("\(userLatitude), \(userLongitude)")
}
override func viewDidLoad() {
super.viewDidLoad()
self.locationManager = CLLocationManager()
/// self.locationManager.requestWhenInUseAuthorization()
checkLocationAuthorizationStatus()
self.locationManager.delegate = self
self.locationManager.startUpdatingLocation()
if CLLocationManager.locationServicesEnabled()
{
getLocale()
}
let locValue = self.locationManager.location?.coordinate
noHeight()
loadShops()
sortList()
print("\(locValue?.latitude), \(locValue?.longitude)")
refresher = UIRefreshControl()
refresher.addTarget(self, action: #selector(ShopTableViewController.handleRefresh), for: UIControlEvents.valueChanged)
if #available(iOS 10, *) {
shopTable.refreshControl = refresher
} else {
shopTable.addSubview(refresher)
}
}
}
What am I doing wrong?
requestWhenInUseAuthorization() is an asynchronous method, so your method that wraps it checkLocationAuthorizationStatus() is also async.
However, in your viewDidLoad, you call
checkLocationAuthorizationStatus()
self.locationManager.delegate = self
self.locationManager.startUpdatingLocation()
This is triggering the locationManager to start before it is authorized. Take a look here at this (somewhat old) link http://nshipster.com/core-location-in-ios-8/
Example
Be sure to conform to CLLocationManagerDelegate
override func viewDidLoad() {
super.viewDidLoad()
self.locationManager = CLLocationManager()
self.locationManager.delegate = self
if CLLocationManager.authorizationStatus() == .notDetermined {
locationManager.requestWhenInUseAuthorization()
} else if CLLocationManager.authorizationStatus() == . authorizedWhenInUse {
startTrackingLocation()
}
}
func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
if status == .authorizedAlways || status == .authorizedWhenInUse {
startTrackingLocation()
// ...
}
}
func startTrackingLocation() {
locationManager.startUpdatingLocation()
getLocale()
//not clear which of these methods require location
let locValue = self.locationManager.location?.coordinate
noHeight()
loadShops()
sortList()
print("\(locValue?.latitude), \(locValue?.longitude)")
}
You need to wait for the authorization response before using location services.
What you are doing now is requesting the authorization and the immediately starting location services. You need to be sure, the app is authorized before getting location.
I'm writing an app and I have an embedded mapview to show user's his location. This is my code so far:
class YourCurrentLocation: UIViewController, CLLocationManagerDelegate {
#IBOutlet weak var mapView: MKMapView!
var locationManager = CLLocationManager()
let regionRadius: CLLocationDistance = 1000
func checkLocationAuthorizationStatus() {
if CLLocationManager.authorizationStatus() == .AuthorizedWhenInUse {
mapView.showsUserLocation = true
centerMapOnLocation(locationManager.location!, map: mapView, radius: regionRadius)
} else {
locationManager.requestAlwaysAuthorization() //requestWhenInUseAuthorization()
}
}
func centerMapOnLocation(location: CLLocation, map: MKMapView, radius: CLLocationDistance) {
let coordinateRegion = MKCoordinateRegionMakeWithDistance(location.coordinate,
radius * 2.0, radius * 2.0)
map.setRegion(coordinateRegion, animated: true)
}
override func viewDidLoad() {
super.viewDidLoad()
// mapView.delegate = self
if CLLocationManager.locationServicesEnabled()
{
//locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.requestAlwaysAuthorization()
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.startUpdatingLocation()
print("location enabled")
checkLocationAuthorizationStatus()
}
else
{
print("Location service disabled");
}
// Do any additional setup after loading the view.
}
}
I also added the two entries to my plist:
NSLocationAlwaysUsageDescription
NSLocationWhenInUseUsageDescription
and also in my xcode I have set to emulate the GPS data on london, UK.
When I run the app - I see the map, but london is not marked. What am I doing wrong?
Btw, I had to comment out this line:
//mapView.delegate = self
in viewDidLoad(), otherwise I had the error:
Cannot assign value of type YourCurrentLocation to type MKMapViewDelegate
and I'm not sure if that's a part of the problem here.
I want to achieve the effect when I display to the user map and a point marked on that map with his location. Can you help me with that?
The problem with your code is that you're trying to point the map to the user's location when the user gives location permission, you're not waiting for the CoreLocation to give you the actual user location.
You need to use the CLLocationManagerDelegate method locationManager(_:didUpdateLocations:) to be notified of when you get the user's actual location, and there you can set the map to point to the user's location.
class ViewController: UIViewController, CLLocationManagerDelegate {
#IBOutlet var mapView: MKMapView!
var locationManager: CLLocationManager?
override func viewDidLoad() {
super.viewDidLoad()
locationManager = CLLocationManager()
locationManager!.delegate = self
if CLLocationManager.authorizationStatus() == .AuthorizedWhenInUse {
locationManager!.startUpdatingLocation()
} else {
locationManager!.requestWhenInUseAuthorization()
}
}
func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
switch status {
case .NotDetermined:
print("NotDetermined")
case .Restricted:
print("Restricted")
case .Denied:
print("Denied")
case .AuthorizedAlways:
print("AuthorizedAlways")
case .AuthorizedWhenInUse:
print("AuthorizedWhenInUse")
locationManager!.startUpdatingLocation()
}
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let location = locations.first!
let coordinateRegion = MKCoordinateRegionMakeWithDistance(location.coordinate, 500, 500)
mapView.setRegion(coordinateRegion, animated: true)
locationManager?.stopUpdatingLocation()
locationManager = nil
}
func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
print("Failed to initialize GPS: ", error.description)
}
}
I am trying to convert an old app in ObjC to Swift as a practice exercise and have ran in to some issues. The way I had it in the old app, it was establishing the CLLocation Manager and then I would use:
manager = [[CLLocationManager alloc]init];
manager.delegate = self;
manager.desiredAccuracy = kCLLocationAccuracyBest;
[manager startUpdatingLocation]
which would call automatically:
-(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation{
}
and from there I could extract all the information I needed. But in swift, there is no autocompletion of this method and I cannot figure out how to reproduce it. The documentation says that
startUpdatingLocation()
will still be called by the delegate, but it isn't happening.
This is what I have so far:
import UIKit
import corelocation
class ViewController: UIViewController,CLLocationManagerDelegate{
#IBOutlet var gpsResult : UILabel
var manager:CLLocationManager!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
manager = CLLocationManager()
manager.delegate = self
manager.desiredAccuracy = kCLLocationAccuracyBest
manager.startUpdatingLocation()
}
func locationManager(manager:CLLocationManager, didUpdateLocations locations:AnyObject[]) {
println("locations = \(locations)")
gpsResult.text = "success"
}
}
Any help or pointers on where to look would be appreciated. Thanks.
EDIT: Updated from Suggestions, but still not working
EDIT2: Seems to be some bug not allowing the method to work properly in the ViewController
You are missing two things. First, you have to ask for permission using requestAlwaysAuthorization or requestWhenInUseAuthorization(). So your viewDidLoad() should be like this:
var locationManager = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()
}
Second, edit your Info.plist as indicated here.
First add this two line in plist file
NSLocationWhenInUseUsageDescription
NSLocationAlwaysUsageDescription
Then this is class working complete implement this
import UIKit
import CoreLocation
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, CLLocationManagerDelegate {
var window: UIWindow?
var locationManager: CLLocationManager!
var seenError : Bool = false
var locationFixAchieved : Bool = false
var locationStatus : NSString = "Not Started"
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
initLocationManager();
return true
}
// Location Manager helper stuff
func initLocationManager() {
seenError = false
locationFixAchieved = false
locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.locationServicesEnabled
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
}
// Location Manager Delegate stuff
// If failed
func locationManager(manager: CLLocationManager!, didFailWithError error: NSError!) {
locationManager.stopUpdatingLocation()
if (error) {
if (seenError == false) {
seenError = true
print(error)
}
}
}
func locationManager(manager: CLLocationManager!, didUpdateLocations locations: AnyObject[]!) {
if (locationFixAchieved == false) {
locationFixAchieved = true
var locationArray = locations as NSArray
var locationObj = locationArray.lastObject as CLLocation
var coord = locationObj.coordinate
println(coord.latitude)
println(coord.longitude)
}
}
// authorization status
func locationManager(manager: CLLocationManager!,
didChangeAuthorizationStatus status: CLAuthorizationStatus) {
var shouldIAllow = false
switch status {
case CLAuthorizationStatus.Restricted:
locationStatus = "Restricted Access to location"
case CLAuthorizationStatus.Denied:
locationStatus = "User denied access to location"
case CLAuthorizationStatus.NotDetermined:
locationStatus = "Status not determined"
default:
locationStatus = "Allowed to location Access"
shouldIAllow = true
}
NSNotificationCenter.defaultCenter().postNotificationName("LabelHasbeenUpdated", object: nil)
if (shouldIAllow == true) {
NSLog("Location to Allowed")
// Start location services
locationManager.startUpdatingLocation()
} else {
NSLog("Denied access: \(locationStatus)")
}
}
}
I'm not sure why, but it seems like startUpdatingLocation isn't presenting the user prompt on the iOS 7 simulator, but when I enabled it manually it worked as expected if I used the newer form of the delegate method:
var manager:CLLocationManager!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
manager = CLLocationManager()
manager.delegate = self
manager.desiredAccuracy = kCLLocationAccuracyBest
manager.startUpdatingLocation()
}
func locationManager(manager:CLLocationManager, didUpdateLocations locations:[AnyObject]) { // Updated to current array syntax [AnyObject] rather than AnyObject[]
println("locations = \(locations)")
}
The format you're using has been deprecated since iOS 5 or 6, so apparently it's not supported at all by the swift bridging layers.
had the same issue. didUpdateLocations - was not working. Run your app. Go to the Settings page -> Privacy -> Location and turn off Location Services. didFailWithError will catch the error about absent Location Services. Then turn it on. Since that moment didUpdateLocations will catch locations.
Here is my very simple code that works:
first add Core Location framework in General/Linked Frameworks and Libraries
then add following into Info.plist:
<key>NSLocationWhenInUseUsageDescription</key>
<string>blablabla</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>blablabla</string>
this is my ViewController.swift file:
import UIKit
import CoreLocation
class ViewController: UIViewController, CLLocationManagerDelegate {
var locationManager:CLLocationManager!
override func viewDidLoad() {
super.viewDidLoad()
locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()
}
func locationManager(manager:CLLocationManager, didUpdateLocations locations: [CLLocation]) {
print("locations = \(locations)")
}
}
For Swift 3
import UIKit
import CoreLocation
class ViewController: UIViewController,CLLocationManagerDelegate {
var locationManager:CLLocationManager!
override func viewDidLoad() {
super.viewDidLoad()
locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func locationManager(_ manager:CLLocationManager, didUpdateLocations locations: [CLLocation]) {
print("locations = \(locations)")
}
}
I hope there are two ways.
var locationManager: CLLocationManager = CLLocationManager()
var initialLocation :CLLocation?
var updatedUserLocation :CLLocation?
override func viewDidLoad() {
super.viewDidLoad() {
//MapView Location
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
locationManager.requestWhenInUseAuthorization()
locationManager.startUpdatingLocation()
locationManager.startUpdatingHeading()
}
Implementing CLLocationManagerDelegate :
//CLLocationManager Delegate
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
// This only works when user location is updated.
gpsProviderStatusLabel.changeStatusToOn(gpsProviderStatusLabel)
}
func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
//Error indicates GPS permission restricted
gpsProviderStatusLabel.changeStatusToOff(gpsProviderStatusLabel)
//Initial Location
initialLocation = locations.first
//Getting Updated Location
updatedUserLocation = locations.last
}
Checking CLLocationDelegate Authorization:
func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
//This method does real time status monitoring.
switch status {
case .NotDetermined:
print(".NotDetermined")
break
case .AuthorizedAlways:
print(".AuthorizedAlways")
gpsProviderStatusLabel.changeStatusToOn(gpsProviderStatusLabel)
break
case .Denied:
print(".Denied")
gpsProviderStatusLabel.changeStatusToOff(gpsProviderStatusLabel)
break
case .AuthorizedWhenInUse:
print(".AuthorizedWhenInUse")
gpsProviderStatusLabel.changeStatusToOn(gpsProviderStatusLabel)
break
case .Restricted:
print(".Restricted")
break
default:
print("Unhandled authorization status")
break
}
}
Note: changeStatusToOn or changeStatusToOff is a UILabel Extenion method which makes the Label text On/Off with Green/Red Colors.
don't forget to add
NSLocationWhenInUseUsageDescription or
NSLocationAlwaysUsageDescription
in your configuration file (target/Info/custom iOS target properties
Add bellow 2 property in info.plist
NSLocationWhenInUseUsageDescription : Location information is used for fraud prevention
Privacy - Location Usage Description : Location information is used for fraud prevention
If you want to get the user location updated by default, without clicking 'Simulate location' everytime, go to
YourProject-->Build Phases-->Link Binary with libraries-->Add corelocation.framework
The location gets updated automatically/by default when you run the app in the simulator. Tested and works in Swift 2 !
This will ask for permission and track if given permission else quit with an alert. Stops tracking on back button press.
