I tried to add an annotation in my map when I click the button. I have written some codes but I am not getting any annotation based on my current location.
#IBAction func addPressed(_ sender: Any) {
guard let location = self.locationManager.location else {
return
}
let annotation = MKPointAnnotation()
annotation.title = "Flooded"
annotation.subtitle = "Reported on 12/10/2018 8:50 AM"
annotation.coordinate = location.coordinate
self.mapView.addAnnotation(annotation)
}
Add this to your view controller and also make sure to assign delegate to self for mapView in viewDidLoad()
Update: As dicsussed in comments, replace your complete view controller code with the code below.
import UIKit
import MapKit
import CoreLocation
class ViewController: UIViewController {
#IBOutlet weak var mapView: MKMapView!
#IBOutlet weak var add: UIButton!
let locationManager = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
mapView.delegate = self
locationManager.delegate = self
checkLocationServices()
}
func setupLocationManager () {
locationManager.desiredAccuracy = kCLLocationAccuracyBest
}
func checkLocationServices() {
if CLLocationManager.locationServicesEnabled() {
setupLocationManager()
checkLocationAuthorization()
} else {
}
}
func checkLocationAuthorization () {
switch CLLocationManager.authorizationStatus() {
case .notDetermined:
locationManager.requestWhenInUseAuthorization()
case .restricted:
let alert = UIAlertController(title: "Location Services disabled", message: "Please enable Location Services in Settings", preferredStyle: .alert)
let okAction = UIAlertAction(title: "OK", style: .default, handler: nil)
alert.addAction(okAction)
present(alert, animated: true, completion: nil)
return
case .denied:
let alert = UIAlertController(title: "Location Services disabled", message: "Please enable Location Services in Settings", preferredStyle: .alert)
let okAction = UIAlertAction(title: "OK", style: .default, handler: nil)
alert.addAction(okAction)
present(alert, animated: true, completion: nil)
return
case .authorizedAlways:
break
case .authorizedWhenInUse:
mapView.showsUserLocation = true // this will bring the blue dot on map
centreZoomviewUserLocation()
locationManager.startUpdatingLocation()
#unknown default:
break
}
}
func centreZoomviewUserLocation () {
if let location = locationManager.location?.coordinate {
let region = MKCoordinateRegion.init(center: location, latitudinalMeters: 10000, longitudinalMeters: 10000)
mapView.setRegion(region, animated: true)
}
}
//MARK:- Button pressed
#IBAction func addPressed(_ sender: Any) {
guard let location = self.locationManager.location else {
return
}
let annotation = MKPointAnnotation()
annotation.title = "Flooded"
annotation.subtitle = "Reported on 12/10/2018 8:50 AM"
annotation.coordinate = location.coordinate
DispatchQueue.main.async {
self.mapView.addAnnotation(annotation)
}
}
}
extension ViewController: CLLocationManagerDelegate {
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let newPin = MKPointAnnotation()
guard let location = locations.last else { return }
let center = CLLocationCoordinate2D(latitude: location.coordinate.latitude, longitude: location.coordinate.longitude)
let region = MKCoordinateRegion.init(center: center, latitudinalMeters: 10000, longitudinalMeters: 10000)
mapView.setRegion(region, animated: true)
newPin.coordinate = location.coordinate
mapView.addAnnotation(newPin)
}
func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
checkLocationAuthorization()
}
}
extension ViewController : MKMapViewDelegate {
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
guard annotation is MKPointAnnotation else { return nil }
let identifier = "Annotation"
var annotationView = mapView.dequeueReusableAnnotationView(withIdentifier: identifier)
if annotationView == nil {
annotationView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: identifier)
annotationView!.canShowCallout = true
} else {
annotationView!.annotation = annotation
}
return annotationView
}
}
So, at the moment I can't seem to figure out how the user can enter a title on the Annotation pins. In my code a pin will appear after a long press on the map, but the title shown of the pin is "Pin".
The only thing I would like to be able to do is for the user of the app to be able to create unique titles of the pins on creation.
import Foundation
import UIKit
import MapKit
class MapsViewController: UIViewController, CLLocationManagerDelegate {
let locationManager:CLLocationManager = CLLocationManager()
#IBOutlet weak var mapView: MKMapView!
override func viewDidLoad() {
super.viewDidLoad()
locationManager.delegate = self
locationManager.requestWhenInUseAuthorization()
locationManager.startUpdatingLocation()
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
for currentLocation in locations{
print("\(index) : \(currentLocation)")
}
}
#IBAction func addPin(_ sender: UILongPressGestureRecognizer) {
let alert = UIAlertController(title: "Title", message: "Please enter location name", preferredStyle: .alert)
//2. Add the text field. You can configure it however you need.
alert.addTextField { (textField) in
textField.text = "Location name"
}
// 3. Grab the value from the text field, and print it when the user clicks OK.
alert.addAction(UIAlertAction(title: "OK", style: .default, handler: { [weak alert] (_) in
let textField = alert?.textFields![0] // Force unwrapping because we know it exists.
print("Text field: \(String(describing: textField?.text))")
DispatchQueue.main.async { self.addPinWithTitle (sender , title : textField?.text ?? "") }
}))
self.present(alert, animated: true, completion: nil)}
func addPinWithTitle(_ sender: UILongPressGestureRecognizer , title : String) {
let location = sender.location(in: self.mapView)
let locCoordinates = self.mapView.convert(location, toCoordinateFrom: self.mapView)
let annotation = MKPointAnnotation()
annotation.coordinate = locCoordinates
annotation.title = title
self.mapView.addAnnotation(annotation)}
}
Please follow the final code
#IBAction func addPin(_ sender: UILongPressGestureRecognizer) {
let alert = UIAlertController(title: "Title", message: "Please enter location name", preferredStyle: .alert)
//2. Add the text field. You can configure it however you need.

textField.placeholder = "Location name"
}
// 3. Grab the value from the text field, and print it when the user clicks OK.
alert.addAction(UIAlertAction(title: "OK", style: .default, handler: { [weak alert] (_) in
let textField = alert?.textFields![0] // Force unwrapping because we know it exists.
print("Text field: \(textField?.text)")
DispatchQueue.main.async {
self.addPinWithTitle (sender , title : textField?.text ?? "")
}

I'm trying to set up an alert that once a user enters a specific location the alert pops up and allows users to "Check-in". After the user checks in the app then notifies an api endpoint that the user successfully checked in. This is my first time working with geofencing and corelocation. I get the basic idea of how to set it up but am not entirely sure how the check-in alert and geofence tie together. Here is my code:
import UIKit
import CoreLocation
class ViewController: UIViewController, CLLocationManagerDelegate{
var manager = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
// Core Location
manager.delegate = self
manager.desiredAccuracy = kCLLocationAccuracyBest
manager.requestWhenInUseAuthorization()
manager.startUpdatingLocation()
var latitude: CLLocationDegrees = 43.039278
var longitude: CLLocationDegrees = -87.932479
var center: CLLocationCoordinate2D = CLLocationCoordinate2DMake(latitude, longitude)
var radius: CLLocationDistance = CLLocationDistance(10.0)
var identifier: String = "storeID"
var geoRegion: CLCircularRegion = CLCircularRegion(center: center, radius: radius, identifier: identifier)
}
func showSimpleAlertWithTitle(title: String!, message: String!, viewController: UIViewController) {
let alert = UIAlertController(title: title, message: message, preferredStyle: .Alert)
let action = UIAlertAction(title: "Check-In", style: .Cancel , handler: nil)
alert.addAction(action)
viewController.presentViewController(alert, animated: true, completion: nil)
}
}
Set notifyOnEntry = true on the CLCircularRegion to be notified when entering or exiting the region.
Implement locationManager:didEnterRegion: delegate method to handle the event.
Example:
override func viewDidLoad() {
super.viewDidLoad()
manager.delegate = self
manager.desiredAccuracy = kCLLocationAccuracyBest
manager.requestWhenInUseAuthorization()
manager.startUpdatingLocation()
var latitude: CLLocationDegrees = 43.039278
var longitude: CLLocationDegrees = -87.932479
var center: CLLocationCoordinate2D = CLLocationCoordinate2DMake(latitude, longitude)
var radius: CLLocationDistance = CLLocationDistance(10.0)
var identifier: String = "storeID"
var geoRegion: CLCircularRegion = CLCircularRegion(center: center, radius: radius, identifier: identifier)
geoRegion.notifyOnEntry = true
manager.startMonitoringForRegion(geoRegion)
}
func locationManager(_ manager: CLLocationManager, didEnterRegion region: CLRegion) {
showSimpleAlertWithTitle("Entered region \(region.identifier)", message: nil)
}
func showSimpleAlertWithTitle(title: String!, message: String!) {
let alert = UIAlertController(title: title, message: message, preferredStyle: .Alert)
let action = UIAlertAction(title: "Check-In", style: .Cancel , handler: nil)
alert.addAction(action)
presentViewController(alert, animated: true, completion: nil)
}

I am trying to run just a simple print function when the user moves the map around using gesture or search (moves the map in general) I've followed the apple ref guides and i get errors.

Make sure you set yourself as your map view's delegate in IB. Also, I'd try moving regionDidChangeAnimated out of viewDidLoad.
