Do as follow may be work for you.
1) Create custom class for the Annotation Pin.
class CustomPointAnnotation: MKPointAnnotation {
var imageName: UIImage!
}
2)Define variable as below.
var locationManager = CLLocationManager()
3) Call below method in viewDidLoad()
func checkLocationAuthorizationStatus() {
if CLLocationManager.authorizationStatus() == .AuthorizedAlways {
map.showsUserLocation = false
} else {
locationManager.requestWhenInUseAuthorization()
}
}
4) Put below code in viewWillAppear()
self.map.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
locationManager.delegate = self
dispatch_async(dispatch_get_main_queue(),{
self.locationManager.startUpdatingLocation()
})
5) Most important implement below method.
func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {
if !(annotation is CustomPointAnnotation) {
return nil
}
let reuseId = "Location"
var anView = mapView.dequeueReusableAnnotationViewWithIdentifier(reuseId)
if anView == nil {
anView = MKAnnotationView(annotation: annotation, reuseIdentifier: reuseId)
anView!.canShowCallout = true
}
else {
anView!.annotation = annotation
}
let cpa = annotation as! CustomPointAnnotation
anView!.image = cpa.imageName
return anView
}
6) Execute below code where you you have received custom pin image
let strLat = "YOUR LATITUDE"
let strLon = "YOUR LONGITUDE"
let info = CustomPointAnnotation()
info.coordinate = CLLocationCoordinate2DMake(strLat.toDouble()!,strLon.toDouble()!)
info.imageName = resizedImage
info.title = dict!["locationName"]! as? String
self.map.addAnnotation(info)
