Hello swift newbie was here. I working on map application and I have problem with region span. I change it to 0.05,0.05 and I want it to be zoom in and out. Then find out when I move around latitude&longitude will change. That make my map keep bounce back to 0.05 span here my code.
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let latispan = 0.05
let longspan = 0.05
let location = locations.last
let center = CLLocationCoordinate2D(latitude: location!.coordinate.latitude, longitude: location!.coordinate.longitude)
let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: latispan, longitudeDelta: longspan))
self.mapView.setRegion(region, animated: true)
//labelText.text = "\(location!.coordinate.latitude) , \(location!.coordinate.longitude)"
labelText.text = "\(region.span.latitudeDelta), \(region.span.longitudeDelta)"
//self.locationManager.stopUpdatingLocation()
}
func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
print("Errors:" + error.localizedDescription)
}
I try to get current span so I might change my latispan, longspan later, but I just can't find a way.

Try Following this may help you :)
func loadMapData() {
if let location = AppDelegate.getInstance().newlocation {
let center = CLLocationCoordinate2D(latitude: location.coordinate.latitude, longitude: location.coordinate.longitude)
let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.05, longitudeDelta: 0.05))
self.map.setRegion(region, animated: true)
}
self.map.removeAnnotations(self.map.annotations)
self.map.showsUserLocation = true
for retailer in self.liststores {
let information = MKPointAnnotation()
information.coordinate = CLLocationCoordinate2D(latitude: retailer.retailer_lat!.doubleValue, longitude: retailer.retailer_lon!.doubleValue)
information.title = retailer.retailer_name
information.subtitle = retailer.retailer_addr1! + retailer.retailer_addr2!
self.map.addAnnotation(information)
}
}
