MapKit zoom to user current location

Question

I am trying to simply show user\'s location on the map, but I need to when app launches, the map should zoom to current location ,but I don\'t know why map doesn\'t zoom at all

Answer 1

Here's another approach for Swift 3, XCode 8.2. First, write out a helper function:

let homeLocation = CLLocation(latitude: 37.6213, longitude: -122.3790)
let regionRadius: CLLocationDistance = 200
func centerMapOnLocation(location: CLLocation)
{
    let coordinateRegion = MKCoordinateRegionMakeWithDistance(location.coordinate,
                                           regionRadius * 2.0, regionRadius * 2.0)
    mapView.setRegion(coordinateRegion, animated: true)
}

Then, call in in viewDidLoad()

mapView.showsUserLocation = true
centerMapOnLocation(location: homeLocation)

This will start the app with the location specified in the variable zoomed in.
