Google Maps vergrößern Zum aktuellen Standort in ios

Question

Google Maps nicht den aktuellen Standort vergrößern könnte nach vielen Lösung über Stapel wie Zoom in to current location on map in Objekt c suchen, aber ich fand eine Lösung, mir helfen konnte, aber es war in swift geschrieben Current Location in Google Maps with swift

so könnte jemand mir helfen mit, dass ??

Answer 1

Sie können die Karte verschieben oder ihre Perspektive mit sehr geringer Latenz ändern. Peilung, Neigung, Position und zoom level der Karte können über das GMSCameraPosition-Objekt programmgesteuert gesteuert werden.

Sie können -animateToZoom: auf Ihrem GMSMapView verwenden, oder Sie können eine GMSCameraPosition erstellen und die und Zoom-Ebene koordinieren und dann -animateToCameraPosition: verwenden oder eine GMSCameraUpdate erstellen und verwenden Sie dann -animateWithCameraUpdate:

GMSCameraPosition *cameraPosition = [GMSCameraPosition cameraWithLatitude:latitude 
longitude:longitude 
zoom:11.0]; 

[self.mapView animateToCameraPosition:cameraPosition]; 

oder

GMSCameraUpdate *update = [GMSCameraUpdate zoomTo:11.0]; 
[self.mapView animateWithCameraUpdate:update]; 

oder

[self.mapView animateToZoom:11.0]; 

Answer 2

func Locationmanager (_ Manager: CLLocationManager, didUpdateLocations Orte: [CLLocation]) {

let locValue:CLLocationCoordinate2D = manager.location!.coordinate 
mapView.animate(toLocation: CLLocationCoordinate2D(latitude: locValue.latitude, longitude: locValue.longitude)) 

    mapView.setMinZoom(4.6, maxZoom: 20)
