I do a app with MapKit and I want the user can select an annotation (clic on) and then open a new view controller.
I do it with the method :
func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) {
performSegue(withIdentifier: "showClic", sender: nil)
}
But this code open the VC when there a cluster of annotation.
And I want to do when there is a cluster of annotation a zoom with the camera and open the VC only when only one annotation is selected.
func fitMapViewToAnnotaionList(annotations: [MKPointAnnotation], userLocation: CLLocationCoordinate2D) -> Void {
let mapEdgePadding = UIEdgeInsets(top: 20, left: 20, bottom: 20, right: 20)
var zoomRect:MKMapRect = MKMapRectNull
for index in 0..<annotations.count {
let annotation = annotations[index]
let aPoint:MKMapPoint = MKMapPointForCoordinate(annotation.coordinate)
let rect:MKMapRect = MKMapRectMake(aPoint.x, aPoint.y, 0.1, 0.1)
if MKMapRectIsNull(zoomRect) {
zoomRect = rect
} else {
zoomRect = MKMapRectUnion(zoomRect, rect)
}
}
let aPoint:MKMapPoint = MKMapPointForCoordinate(userLocation)
let rect:MKMapRect = MKMapRectMake(aPoint.x, aPoint.y, 0.1, 0.1)
if MKMapRectIsNull(zoomRect) {
zoomRect = rect
} else {
zoomRect = MKMapRectUnion(zoomRect, rect)
}
mapView.setVisibleMapRect(zoomRect, edgePadding: mapEdgePadding, animated: true)
}

I'm trying to update some map components while dragging an annotations like highlighting a specific MGLPolygon and panning the map if the annotation is already dragged near the edge. I will use the later for this problem.
I tried the code https://docs.mapbox.com/ios/maps/examples/draggable-views/ and added some lines. Here's the exact copy with my changes.

Here is the code explaining the Adonis's solution. Essentially add a pan gesture to a custom annotation's view and update the coords as and when the annotation is panned.

)
let tapGesture = UITapGestureRecognizer(

self.isUserInteractionEnabled = true
self.addGestureRecognizer(panGesture)
self.addGestureRecognizer(tapGesture)
for recognizer in self.gestureRecognizers! where recognizer is UITapGestureRecognizer {
tapGesture.require(toFail: recognizer)
}
for recognizer in self.gestureRecognizers! where recognizer is UIPanGestureRecognizer {
panGesture.require(toFail: recognizer)
}
}
#objc func draggedView(_ sender: UIPanGestureRecognizer) {
annotationObject?.draggable!.isCurrentlyDragging = true
let point = sender.location(in: MapManager.shared.mapView)
let coordinates = MapManager.shared.mapView.convert(

toCoordinateFrom: MapManager.shared.mapView
)
annotationObject?.coordinate = coordinates
if sender.state == .ended {
// endDragging()
} else if sender.state == .began {

I'm trying to create simple custom map annotations on Mapbox iOS (5.5.0) by implementing MGLMapViewDelegate protocol. Annotations are actually added to the map, but they are invisible. I can predict its coordinate and open its callout, so, I know it's there.
I have even tried copying the exact codes given on Mapbox examples to get the same result. Can it be a lack of some framework elements?
My code:
class MainViewController: UIViewController, MGLMapViewDelegate {
override func viewDidLoad() {
super.viewDidLoad()
// Set the map’s size, style, center coordinate, zoom level, and tint color.
let mapView = MGLMapView(frame: view.bounds)
let coordinates = CLLocationCoordinate2D(latitude: 40.4561, longitude: 49.7263)
mapView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
mapView.styleURL = MGLStyle.darkStyleURL(withVersion: 9)
mapView.setCenter(coordinates, zoomLevel: 15, animated: false)
//mapView.userTrackingMode = .followWithHeading
//mapView.showsUserHeadingIndicator = true
view.addSubview(mapView)
mapView.delegate = self
let marker = MGLPointAnnotation()
marker.coordinate = coordinates
marker.title = "Area 51"
marker.subtitle = "There is no way in!"
mapView.addAnnotation(marker)
}
// Use the default marker. See also: our view annotation or custom marker examples.
func mapView(_ mapView: MGLMapView, viewFor annotation: MGLAnnotation) -> MGLAnnotationView? {
guard annotation is MGLPointAnnotation else {
return nil
}
let annotationAvailable = isAnnotationAvailable(annotation)
let reuseIdentifier = "\(annotationAvailable)"
var annotationView = mapView.dequeueReusableAnnotationView(withIdentifier: reuseIdentifier)
if (annotationView == nil) {
annotationView = MGLAnnotationView()
annotationView = CustomAnnotationView(reuseIdentifier: reuseIdentifier)
annotationView!.bounds = CGRect(x: 0, y: 0, width: 40, height: 40)
if (!annotationAvailable) {
annotationView!.backgroundColor = UIColor(displayP3Red: 255, green: 0, blue: 0, alpha: 1)
}
else {
annotationView!.backgroundColor = UIColor(displayP3Red: 0, green: 255, blue: 0, alpha: 1)
}
}
return annotationView
}
// Allow callout view to appear when an annotation is tapped.
func mapView(_ mapView: MGLMapView, annotationCanShowCallout annotation: MGLAnnotation) -> Bool {
return true
}
func isAnnotationAvailable(_ annotation: MGLAnnotation) -> Bool {
return false
}
}
class CustomAnnotationView: MGLAnnotationView {
override func layoutSubviews() {
super.layoutSubviews()
// Use CALayer’s corner radius to turn this view into a circle.
layer.cornerRadius = bounds.width / 2
layer.borderWidth = 2
layer.borderColor = UIColor.white.cgColor
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Animate the border width in/out, creating an iris effect.
let animation = CABasicAnimation(keyPath: "borderWidth")
animation.duration = 0.1
layer.borderWidth = selected ? bounds.width / 4 : 2
layer.add(animation, forKey: "borderWidth")
}
}
The result:
Mapbox Screenshot
When the animation is executing , i try to click the moving annotationView ,but cannnot be selected, the mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) hasn't been called
func addMoveAnimation() {
guard let ano = annotation as? Annotation else {
return
}
animator = UIViewPropertyAnimator.init(duration: 10, curve: .linear, animations: {
ano.coordinate = CLLocationCoordinate2D(latitude: 32.449819, longitude: 112.292726)
})
animator?.startAnimation()
animator?.addCompletion({ (position) in
print(position.des,"coor:", ano.coordinate)
})
}
i try to add a UITapGestureRecognizer for the annotationView， and it really works, but then quickly changed to be deseleted, and the mapView(_ mapView: MKMapView, didDeselect view: MKAnnotationView) also be called
#objc func handleGes() {
print("tap ges click")
removeAnimation()
let currentFrame = (layer.presentation() as! CALayer).frame
layer.removeAllAnimations()
let point = CGPoint.init(x: currentFrame.midX, y: currentFrame.midY)
let coor = mapView?.convert(point, toCoordinateFrom: mapView)
guard let ano = annotation as? Annotation, let coordinate = coor else {
return
}
ano.coordinate = coordinate
print(ano.coordinate)
mapView?.selectAnnotation(ano, animated: false)
}
I want to do animation like "when scroll collection view cell the annotation pin goes Up/Down at the end of scrolling. But how to do animation like annotation pin goes Up when start scrolling and annotation pin goes Down when scrolling end in collection view
//code --> For Scrolling
func scrollViewDidEndDecelerating(scrollView: UIScrollView) {
if scrollView == collectionView {
NSLog("page collection %d",Int(scrollView.contentOffset.x/scrollView.frame.size.width))
self.UpdateMapAnotationPin(Int(scrollView.contentOffset.x/scrollView.frame.size.width))
}
}
// -->When Update Pin
func UpdateMapAnotationPin(vIndex : Int) {
if self.mapAnnotations.count != 0 {
let info = self.mapAnnotations[vIndex]
let aView = map.viewForAnnotation(info)
info.imageName = "ic_map_pin1"
info.tagPin = vIndex
aView?.image = UIImage(named: info.imageName)
if aView != nil {
self.animationWithView(aView!)
}
}
}
// --> For animation
func animationWithView(mkView : MKAnnotationView) {
let point:MKMapPoint = MKMapPointForCoordinate(mkView.annotation!.coordinate);
let endFrame:CGRect = mkView.frame;
mkView.frame = CGRectMake(mkView.frame.origin.x, mkView.frame.origin.y - 20, mkView.frame.size.width, mkView.frame.size.height);
let delay = 0.03
UIView.animateWithDuration(0.5, delay: delay, options: UIViewAnimationOptions.CurveLinear, animations:{() in
mkView.frame = endFrame
}, completion:{(Bool) in
UIView.animateWithDuration(0.05, delay: 0.0, options: UIViewAnimationOptions.CurveLinear, animations:{() in
mkView.transform = CGAffineTransformMakeScale(1.0, 1.0) }, completion: {(Bool) in
UIView.animateWithDuration(0.3, delay: 0.0, options: UIViewAnimationOptions.CurveLinear, animations:{() in
mkView.transform = CGAffineTransformIdentity
}, completion: nil)
})
})
}
I think you want to animated like AirBnb app annotations.
You have to select the pin by calling it's viewforAnimation method
Steps
1.Make annotation using by assigning the custom id like this
class GridAnnotation: NSObject ,MKAnnotation{
var title: String?
var coordinate: CLLocationCoordinate2D
var info: String
var index: String
init(title: String, coordinate: CLLocationCoordinate2D, info: String,index: String) {
self.title = title
self.coordinate = coordinate
self.info = info
self.index = index
}
}
override func viewDidLoad() {
super.viewDidLoad()
let annotationStart = GridAnnotationStart(title: "", coordinate: firstLocation.coordinate, info: "\(zoneCreateModal.id)",index: "\(0)")
self.mapVw.addAnnotation(annotationSta
rt)
}
2.Get all annotations
let arrAllAnnotations = self.mapVw.annotations.filter { $0 !== self.mapVw.userLocation }
for someAnnotation in annotationsToRemove {
let strId = "Your current id"
if someAnnotation.isKind(of: AnnotationModal.self) {
let annotaion = someAnnotation as! AnnotationModal
if annotaion.info == strId {
//Call view for animation
self.mapVw.selectAnnotation(someAnnotation, animated: true)
self.mapVw.view(for: someAnnotation)
}
}
}
5.Set type of new selected annoatation in viewForAnnotation
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
if (annotation.isKind(of: MKUserLocation.self)) {
return nil
}
if annotation.isKind(of: GridAnnotationZoomModal.self) {
let anView = MKAnnotationView(annotation: annotation, reuseIdentifier: "landingPoints")
let annotationInfo = annotation as! GridAnnotationZoomModal
imgView.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
if anView.isSelected == true {
imgView.image = UIImage(named: "Your selected image name")
}else{
imgView.image = UIImage(named: "Your image not selected name")
}
anView.isDraggable = false
anView.isEnabled = true
anView.isUserInteractionEnabled = true
anView.tag = Int(annotationInfo.index)!
anView.addSubview(imgView)
anView.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
anView.centerOffset = CGPoint(x: 0,y: -15)
return anView
}
return nil
}
I am learning Swift and want to create a subclass of MKMapKit to encapsulate some specific functionality, like checking distance between two points and creating custom annotations and separate all the map code into one class.
I have created a class:
class GameMapViewController: MKMapView, MKMapViewDelegate{...}
I initiate the class in code in the main view controller (and adding it as a subview to a view on the storyboard so I can control where it is more easily):
gameMap = GameMapViewController(container: mapViewHolder)
which sets everything up ok and all works EXCEPT for when I want to trigger a segue from a custom annotation:
func mapView(mapView: MKMapView!, didSelectAnnotationView view: MKAnnotationView!) {...}
The didSelectAnnotationView gets called when I tap on an annotation callout but nothing has the method performSegueWithIdentifier that I am looking for, that all the solutions to similar questions suggest I should be using....
(I have tried putting a MapKit View onto the storyboard and changing its class to use GameMapViewController but none of the init functions get fired)
I am guessing its something to with how I am initialising my custom class?

It's because you're confusing views and view controllers. You have a view (subclass of MKMapView, but you're naming it and trying to use it as a controller. It is also doings the job of a controller.
So, you should really have a view controller which owns and configures a map view (plain MKMapView), and then it can interact with segues.
