I need to add an Id for each annotation in map to open new view controller by clicking on info button in annotation , my problem is in prepare and perform segue, I created it, but I don't know how to pass the id to the segue.
I created sub class for annotation to store the ID that comes from JSON
Thats parts of my code :
Getting all data from JSON :
for location in self.locations {
let annotation:MyAnnotation = MyAnnotation()
annotation.title = location["truck_name"] as? String
annotation.customTruckId = location["truck_id"] as? String
annotation.coordinate = CLLocationCoordinate2D(latitude: (location["coor_x"] as! NSString).doubleValue, longitude: (location["coor_y"] as! NSString).doubleValue)
self.AllMapView.addAnnotation(annotation)
}
Sub class I created:
class MyAnnotation : MKPointAnnotation {
var customTruckId : String?
}
Problem is here in segue :
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if (segue.identifier == "ShowTruckFromMap") {
let des_VC = segue.destination as! TruckDetailsVC
des_VC.truck_id = "How to get Id here !"
}
}
func mapView(_ mapView: MKMapView, annotationView view: MKAnnotationView, calloutAccessoryControlTapped control: UIControl) {
if control == view.rightCalloutAccessoryView {
performSegue(withIdentifier: "ShowTruckFromMap", sender: self)
}
}
Thanks
You can show your UIViewController without using Segue.
You must at first put an identifier to your UIViewController in :
identity Inspector -> Identity -> storyboard ID = TruckDetailsVCIdentifier
func mapView(_ mapView: MKMapView, annotationView view: MKAnnotationView, calloutAccessoryControlTapped control: UIControl) {
if control == view.rightCalloutAccessoryView {
let mainStoryboard:UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let desController = mainStoryboard.instantiateViewController(withIdentifier: "TruckDetailsVCIdentifier") as! TruckDetailsVC
let TruckAnnotation = view.annotation as? MyAnnotation
desController.truck_id = (TruckAnnotation?.customTruckId!)!
show(desController, sender: self)
}
}
I found Answer:
func mapView(_ mapView: MKMapView, annotationView view: MKAnnotationView, calloutAccessoryControlTapped control: UIControl) {
if control == view.rightCalloutAccessoryView {
let mainStoryboard:UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let desController = mainStoryboard.instantiateViewController(withIdentifier: "TruckDetailsVC") as! TruckDetailsVC
let TruckAnnotation = view.annotation as? MyAnnotation
desController.truck_id = (TruckAnnotation?.customTruckId!)!
show(desController, sender: self)
}
}
Thanks for all

I managed to make my annotations with a personalized image by annotation and the title in the popup.
My question: Is it possible to also add the title below the annotation?
Thank you in advance for your feedback.
The view controller
func mapView(_ mapView: MKMapView, annotationView view: MKAnnotationView, calloutAccessoryControlTapped control: UIControl) {
let pageDecouverte = listeDesPoints[view.tag]
selectedLieuDecouverte = pageDecouverte
self.performSegue(withIdentifier: "showPageDecouverte", sender: nil)
}
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView?
{
if !(annotation is MKPointAnnotation) {
return nil
}
let annotationIdentifier = "location"
var annotationView = carteRegion.dequeueReusableAnnotationView(withIdentifier: (annotationIdentifier))
if annotationView == nil {
annotationView = MKAnnotationView(annotation: annotation, reuseIdentifier: annotationIdentifier)
annotationView!.canShowCallout = true
}
else {
annotationView!.annotation = annotation
}
if annotation is MyAnnotation {
let imageName = (annotation as! MyAnnotation).imageName
annotationView?.tag = (annotation as! MyAnnotation).tag
if imageName != nil{
let interetImage = UIImage(named: imageName!)
annotationView!.image = interetImage
}
}
annotationView?.clusteringIdentifier = annotationIdentifier
annotationView?.canShowCallout = true
annotationView?.rightCalloutAccessoryView = UIButton(type:.detailDisclosure)
return annotationView
}
}
For my MyAnnotation
import UIKit
import MapKit
import Parse
class MyAnnotation: MKPointAnnotation {
var imageName: String?
var annotationTitle: String?
var tag : Int = 0
var pageDecouverte:PFPageDecouverte?
}
Instead of MKAnnotationView use the subclass MKMarkerAnnotationView to render the title below the marker.
Also in MyAnnotation rename annotationTitle to title, then MKMarkerAnnotationView automatically knows what to render.
See the definition of protocol MKAnnotation to see why.
In my application, I have stored coordinates in FireBase and am displaying those coordinates on a Map View in the code below. The current location of the user is also being harnessed. I would like the locations I have stored in FireBase to be represented by the generic Apple Maps pins, but I do not know how to get the app to work unless I use custom images as pins instead. Also, the generic "blue dot" of the user displayed on the map to represent the current location will not appear for me. In different projects in which the locations are stored in-app rather than in FireBase, the generic pins and blue dot appear just as I would like them to. How can I fix this?
I have tried changing bits and pieces of the code, but I am rather new to Swift and the programming world in general, and cannot find a solution.

Use MKPinAnnotationView instead of MKAnnotationView
Set mapView.showsUserLocation = true to show user location (blue dot)
I have two pin annotations on my map. I created a info button to perform the segue. But the button appears only on one annotation. Can anyone help me please? For the annotations I created a function that I put into the viewdidload method.
Here`s the code:

#IBOutlet weak var mapView: MKMapView!
var locManager: CLLocationManager!
override func viewDidLoad() {
super.viewDidLoad()

meinkartenPunkt2()
locManager = CLLocationManager()
locManager.requestWhenInUseAuthorization()
// Do any additional setup after loading the view.
mapView.delegate = self
}

super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.

}
*/
func mapView(_ mapView: MKMapView,didUpdate userLocation: MKUserLocation){
mapView.region.center=userLocation.coordinate
mapView.showAnnotations(mapView.annotations, animated: true)
}
func meinkartenPunkt1() {
let breite: CLLocationDegrees = 8.737653
let länge: CLLocationDegrees = 47.504333
let Koordinaten = CLLocationCoordinate2DMake(länge, breite)
let Span = MKCoordinateSpanMake(0.01, 0.01)
let Region = MKCoordinateRegionMake(Koordinaten, Span)
mapView.setRegion(Region, animated: true)
let Stecknadel = MKPointAnnotation()
Stecknadel.coordinate = Koordinaten
Stecknadel.title = "Heiligberg"
mapView.addAnnotation(Stecknadel)
}

let Region = MKCoordinateRegionMake(Koordinaten, Span)
mapView.setRegion(Region, animated: true)
let Stecknadel = MKPointAnnotation()
Stecknadel.coordinate = Koordinaten
Stecknadel.title = "Kanti Rychenberg"
mapView.addAnnotation(Stecknadel)
}
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView?{
if annotation is MKUserLocation {return nil}
let reuseId = "pin"
var pinView = mapView.dequeueReusableAnnotationView(withIdentifier: reuseId) as? MKPinAnnotationView
if pinView == nil {
pinView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: reuseId)
pinView!.canShowCallout = true
pinView!.animatesDrop = true
let calloutButton = UIButton(type: .detailDisclosure)
pinView!.rightCalloutAccessoryView = calloutButton
pinView!.sizeToFit()
}
else {
pinView!.annotation = annotation
}
return pinView
}
func mapView(_ mapView: MKMapView, annotationView view: MKAnnotationView,
calloutAccessoryControlTapped control: UIControl) {
if control == view.rightCalloutAccessoryView {
performSegue(withIdentifier: "bookDetails", sender: self)
}
}
}
When looking at your source code, I cannot directly see an answer, however I see an immediate problem. You do some important setup on the pinView, while it is nil. To be honest, this code certainly crashes, if it is ever reached:
if pinView == nil {
pinView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: reuseId)
pinView!.canShowCallout = true
Luckily for you, pinView never is nil however, as the mapView creates the pinView successfully. What you probably want to do, is to set the calloutButton, if it is not set. So instead of if pinView == nil you write:
if pinView?.rightCalloutAccessoryView == nil {
// Initialize the rightCalloutAccessoryView here
}
Tip: In general you should avoid force unwraps with ! as it leads to crashes. Try to use optional chaining with ? instead.
I'm doing the app for viewing IP cameras and want to add cameras to the map so you can click on the desired marker and go to see the desired camera. I have a map and PlayerViewController which reproduce a webcam.
Now each marker only transmits the first stream of the webcam. Help me. How to make different webcam worked?

First of All MKAnnotation is a Protocol so you can implement this protocol in your model class, lets say "Camera"
import UIKit
import MapKit
class Camera: NSObject, MKAnnotation {
var name: String = ""
var urlString :String = ""
var coordinate: CLLocationCoordinate2D = CLLocationCoordinate2D(latitude: 0, longitude: 0)
var imageName : String = ""
init(name:String,camUrl:String,imageNamed:String,latitude:CLLocationDegrees,longitude:CLLocationDegrees) {
super.init()
self.name = name
self.urlString = camUrl
self.imageName = imageNamed
guard latitude != 0 && longitude != 0 else
{
return
}
guard latitude.isNaN || longitude.isNaN else
{
return
}
self.coordinate = CLLocationCoordinate2D(latitude: latitude, longitude: longitude)
}
// Title and subtitle for use by selection UI.
public var title: String? {
get{
return self.name
}
}
}
Then you can reduce your ViewController code like this
import UIKit
import MapKit
class ViewController: UIViewController {
#IBOutlet weak var mapView: MKMapView!
var moscow: [Camera] = []
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
self.moscow = [Camera(name: "cam1", camUrl: "http://example/1.m3u8", imageNamed: "1.jpg", latitude: 55.753989, longitude: 37.620235),
Camera(name: "cam2", camUrl: "http://example/2.m3u8", imageNamed: "2.jpg", latitude: 55.741308, longitude: 37.653914),
Camera(name: "cam3", camUrl: "http://example/3.m3u8", imageNamed: "3.jpg", latitude: 55.742468, longitude: 37.629292)]
self.mapView.addAnnotations(self.moscow)
self.mapView.delegate = self
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
extension ViewController : MKMapViewDelegate
{
func mapView(_ mapView: MKMapView, regionWillChangeAnimated animated: Bool) {
print(#function)
}
// Called when the annotation was added
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
if annotation is MKUserLocation {
return nil
}
let reuseId = "pin"
var pinView = mapView.dequeueReusableAnnotationView(withIdentifier: reuseId) as? MKPinAnnotationView
if pinView == nil {
pinView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: reuseId)
pinView?.animatesDrop = true
pinView?.canShowCallout = true
pinView?.isDraggable = true
pinView?.pinColor = .purple
let rightButton: AnyObject! = UIButton(type: UIButtonType.detailDisclosure)
pinView?.rightCalloutAccessoryView = rightButton as? UIView
} else {
pinView?.annotation = annotation
}
return pinView
}
func mapView(_ mapView: MKMapView, annotationView view: MKAnnotationView, calloutAccessoryControlTapped control: UIControl) {
print(#function)
let camera = view.annotation as! Camera
if control == view.rightCalloutAccessoryView {
performSegue(withIdentifier: "toTheMoon", sender: camera)
}
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "toTheMoon" {
let controller = segue.destination as! PlayerViewController
controller.webcamURL = (sender as! Camera).urlString
controller.webcamTitle = (sender as! Camera).name
}
}
func mapView(_ mapView: MKMapView, annotationView view: MKAnnotationView, didChange newState: MKAnnotationViewDragState, fromOldState oldState: MKAnnotationViewDragState) {
if newState == MKAnnotationViewDragState.ending {
let droppedAt = view.annotation?.coordinate
print(droppedAt)
}
}
}
Hope this helps
I want to pass the data (quelmonument) from a pinpoint on a Mapkit to another viewcontroller. With this code just below, i could get the good value but i don't know i could do to pass the data.
func mapView(mapView: MKMapView!, annotationView: MKAnnotationView, calloutAccessoryControlTapped control: UIControl) {
if control == annotationView.rightCalloutAccessoryView {
if let pinannotation = annotationView.annotation as? Artwork{
println("status was = \(pinannotation.quelmonument)")
var indexmonument = pinannotation.quelmonument
performSegueWithIdentifier("hugo", sender: self)
}
}
}
I have tried to send the value 2, and it's working, but instead of 2 i would like send "quelmonument" variable. Could you give me pls an hint ?
func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "hugo"
{
if let destinationVC = segue.destinationViewController as? MonumentViewController{
destinationVC.numberToDisplay = 2
}
}
}
