Hi, I loved the material available here and in articles section at RW, i tried something very beginner level and was able to achieve some success with it , but what i need is to be able to zoom in on location if i keep pressing the zoom button, like when we pinch , below is my code section wise Start of file , ``` import UIKit import MapKit class MapViewController: UIViewController, MKMapViewDelegate, CLLocationManagerDelegate { var mapView: MKMapView! override func loadView() { mapView = MKMapView() view = mapView ``` **Then i add a button to zoom in on the location** ``` let zoomButton = UIButton() zoomButton.setTitle("ZOOM", for: .normal) zoomButton.setTitleColor(.blue, for: .normal) zoomButton.frame = CGRect(x: 0, y: 0, width: 100, height: 50) ``` **Then i add the segmentedView** ``` let segmentedView = UISegmentedControl(items: ["standard", "hybrid","satellite"]) segmentedView.backgroundColor = UIColor.white.withAlphaComponent(0.5) segmentedView.selectedSegmentIndex = 0 ``` **Then i set the default constraint to false and add zoom button and segmentedview** ``` segmentedView.translatesAutoresizingMaskIntoConstraints = false zoomButton.translatesAutoresizingMaskIntoConstraints = false view.addSubview(segmentedView) view.addSubview(zoomButton) ``` **Then i add the constraints to both button and segmentedview** ``` let topViewConstraint = segmentedView.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor, constant: 8) let margin = view.layoutMarginsGuide let leadingConstraint = segmentedView.leadingAnchor.constraint(equalTo: margin.leadingAnchor) let trailingConstraint = segmentedView.trailingAnchor.constraint(equalTo: margin.trailingAnchor) let topZoom = zoomButton.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor, constant: 35) let leadingZoom = zoomButton.leadingAnchor.constraint(equalTo: margin.leadingAnchor) let trailingZoom = zoomButton.trailingAnchor.constraint(equalTo: margin.trailingAnchor) topViewConstraint.isActive = true leadingConstraint.isActive = true trailingConstraint.isActive = true topZoom.isActive = true leadingZoom.isActive = true trailingZoom.isActive = true ``` **Then i add target to segmentedView** `segmentedView.addTarget( **self** , action: **#selector** (updateViewPatch), for: .valueChanged)` **Then i add target to zoombutton** zo`omButton.addTarget( **self** , action: **#selector** (MapViewController.pressedAction(sender:)), for: .touchUpInside)` **Now i come out side the loadView and add the func for button and segmentedView** **Out side of viewload method now, for segmentedView** ``` @objc func updateViewPatch(_ sender: UISegmentedControl) { switch sender.selectedSegmentIndex { case 0: mapView.mapType = .standard case 1: mapView.mapType = .hybrid case 2: mapView.mapType = .satellite default: break } } ``` **Now before i add the func for zoom button inside of viewdidload method** ``` manager.delegate = self manager.desiredAccuracy = kCLLocationAccuracyBest manager.requestWhenInUseAuthorization() manager.startUpdatingLocation() ``` **Also add this line out side of viewdidload** `let manager = CLLocationManager()` **Now the function for button pressed** ``` @objc func pressedAction(sender: UIButton!) { let locationManager = CLLocationManager() locationManager.requestWhenInUseAuthorization() let location = manager.location let span:MKCoordinateSpan = MKCoordinateSpan(latitudeDelta: 0.1, longitudeDelta: 0.1) let myLocation: CLLocationCoordinate2D = CLLocationCoordinate2DMake((location?.coordinate.latitude)!, (location?.coordinate.longitude)!) var region: MKCoordinateRegion = MKCoordinateRegion(center: myLocation, span: span) mapView.setRegion(region, animated: true) self.mapView.showsUserLocation = true } ``` Now with all this i am able to see a location on my real iphone device , but when i press the zoom button again and again it does not zoom in like when we pinch and stretch the map , how can i keep zooming in … **i tried adding** ``` region.span.longitudeDelta = region.span.longitudeDelta + 0.01 region.span.latitudeDelta = region.span.latitudeDelta + 0.01 ``` By converting the let to var , but it remains zoomed at predefined coordinates and do not get closer to location , can any one please guide how i can zoom in by press of a button Thanks ---
