Hello,
I would like to store, save users data inside the app (Best option to store it in the cloud) with location the user reach. The loaction check in point on the map is within radius 100 meters. So the thing I would like to do is to show as a list in the second viewcontroller Zdobyte Szczyty, names of the locations sczyt.name from the first ViewController (the one with the map) that user reached (clicked with a button to check in). I thought about adding a button to the annotation view, which should do the check in if the user is in this radius - but it does not show me the button, just pin. Here is my code:
import UIKit
import MapKit
class ViewController: UIViewController, MKMapViewDelegate{
let locationManager = CLLocationManager()
struct Szczyt {
let name: String
let opis: String
let lattitude: CLLocationDegrees
let longtitude: CLLocationDegrees
var coordinate: CLLocationCoordinate2D {
.init(latitude: lattitude, longitude: longtitude)
}
}
@IBOutlet weak var mapView: MKMapView!
@IBAction func mapTypeSegmentSelected(_ sender: UISegmentedControl) {
switch sender.selectedSegmentIndex {
case 0:
mapView.mapType = .standard
case 1:
mapView.mapType = .satellite
default:
mapView.mapType = .hybrid
}
}
private(set) var circles: [MKCircle]!
let szczyty = [Szczyt(name: "one", opis: "describtion", lattitude: 53.865061725039226, longtitude: 17.708595782487315),
Szczyt(name: "two", opis: "describtion2", lattitude: 55.893874478583854, longtitude: 24.896341184611302),
Szczyt(name: "Skrzyczne", opis: "describtion3", lattitude: 49.685059170137386, longtitude: 19.030076144463138)]
override func viewDidLoad() {
super.viewDidLoad()
mapView.register(MKMarkerAnnotationView.self, forAnnotationViewWithReuseIdentifier: "identifier")
checkLocationServices()
znajdzSzczytyNaMapie(szczyty)
circles = szczyty.map {
MKCircle(center: $0.coordinate, radius: 100)
}
mapView.addOverlays(circles!)
mapView.delegate = self
}
func checkLocationServices() {
if CLLocationManager.locationServicesEnabled() {
checkLocationAuthorization()
} else {
// Show alert letting the user know they have to turn this on.
}
}
func checkLocationAuthorization() {
switch CLLocationManager.authorizationStatus() {
case .authorizedWhenInUse:
mapView.showsUserLocation = true
case .denied: // Show alert telling users how to turn on permissions
break
case .notDetermined:
locationManager.requestWhenInUseAuthorization()
mapView.showsUserLocation = true
case .restricted: // Show an alert letting them know what’s up
break
case .authorizedAlways:
break
}
}
func znajdzSzczytyNaMapie(_ szczyty: [Szczyt]) {
for szczyt in szczyty {
let annotations = MKPointAnnotation()
annotations.title = szczyt.name
annotations.subtitle = szczyt.opis
annotations.coordinate = CLLocationCoordinate2D(latitude:
szczyt.lattitude, longitude: szczyt.longtitude)
mapView.addAnnotation(annotations)
}
}
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
guard !(annotation is MKUserLocation) else { return nil }
//let annotationView = MKMarkerAnnotationView(annotation: annotation, reuseIdentifier: "MyMarker")
let identifier = "identifier"
//guard let annotationView = mapView.dequeueReusableAnnotationView(withIdentifier: identifier) as? MKMarkerAnnotationView else { return nil }
guard let annotationView = mapView.dequeueReusableAnnotationView(withIdentifier: identifier, for: annotation) as? MKMarkerAnnotationView else { return nil }
let btn = UIButton(type: .detailDisclosure)
annotationView.rightCalloutAccessoryView = btn
switch annotation.title!! {
case "one":
annotationView.markerTintColor = UIColor(red: 0.86, green: 0.99, blue: 0.79, alpha: 1.00)
annotationView.glyphImage = UIImage(named: "one_pic")
case "two":
annotationView.markerTintColor = UIColor(red: 0.80, green: 0.98, blue: 0.73, alpha: 1.00)
annotationView.glyphImage = UIImage(named: "two_pic"")
case "Skrzyczne":
annotationView.markerTintColor = UIColor(red: 0.02, green: 0.61, blue: 0.69, alpha: 1.00)
annotationView.glyphImage = UIImage(named: "three_pic"")
default:
annotationView.markerTintColor = UIColor.green
annotationView.glyphImage = UIImage(named: "default")
}
return annotationView
}
func mapView(_ mapView: MKMapView, rendererFor overlay: MKOverlay) -> MKOverlayRenderer {
let circleRenderer = MKCircleRenderer(overlay: overlay)
circleRenderer.strokeColor = UIColor.green
circleRenderer.fillColor = UIColor.green
circleRenderer.alpha = 0.3
circleRenderer.lineWidth = 1.0
return circleRenderer
}
}
This is my Zdobyte Szczyty viewcontroller:
import UIKit
import SwiftUI
class Zdobyte_ViewController: UIViewController {
struct ContentView: View {
var body: some View {
Text("Test viewcontroller gór")
}
}
override func viewDidLoad() {
super.viewDidLoad()
}
}
Here is the button view I would like to have with the pin image, but now it only shows the pin with the image:
This is how my viewcontrollers view looks like:
Here is how to add a button to annotation:

That seems close to what you've done, as MKPinAnnotationView is deprecated.
Or more recent:

Replace as well MKPinAnnotationView
