MKMapView center and zoom in

Question

I am using MKMapView on a project and would like to center the map on a coordinate and zoom in. Just like Google maps has:

GMSCameraPosition.camera(withLatitude: -33.8683,
                                  longitude: 151.2086,
                                  zoom: 6)

Is there any Mapkit method for this?

Answer 1

Here is a method I use to center your map on a pre-defined CLLocation using MKCoordinateRegion.

func centerMapOnLocation(_ location: CLLocation, mapView: MKMapView) {
    let regionRadius: CLLocationDistance = 1000
    let coordinateRegion = MKCoordinateRegionMakeWithDistance(location.coordinate,
        regionRadius * 2.0, regionRadius * 2.0)
    mapView.setRegion(coordinateRegion, animated: true)
}

Answer 2

You'd create a MKCoordinateRegion object and set that as the region on your MKMapView object.

MKCoordinateRegion mapRegion;   
CLLocationCoordinate2D coordinate;
coordinate.latitude = 0;
coordinate.longitude = 0;    
mapRegion.center = coordinate;
mapRegion.span.latitudeDelta = 0.2;
mapRegion.span.longitudeDelta = 0.2;

[mapView setRegion:mapRegion animated: YES];

Answer 3

Put the below code in your CustomMapView subclass of MKMapView Call is from init

class CustomMapView: MKMapView {
private func zoom() {
            let dortmundLocation = CLLocation(latitude: 51.516667, longitude: 7.466667)
            let dortmunRegion = MKCoordinateRegion(center: CLLocationCoordinate2D(latitude: dortmundLocation.coordinate.latitude, longitude: dortmundLocation.coordinate.longitude), span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01))
            self.setRegion(dortmunRegion, animated: true)
        }
}
