Swift Fehler - Verwendung von ungelösten Bezeichner 'kGMSMarkerAnimationPop'

Question

Ich erhalte diese Störung

Verwendung von ungelösten Kennung 'kGMSMarkerAnimationPop'

wenn ich den folgenden Code in Swift 3:

let camera = GMSCameraPosition.camera(withLatitude: location.coordinate.latitude, longitude: location.coordinate.longitude, zoom: 14) 
mapView = GMSMapView.map(withFrame: CGRect.zero, camera: camera) 
mapView?.isMyLocationEnabled = true 
mapView?.settings.myLocationButton = true 
view = mapView 
let marker = GMSMarker() 
marker.position = CLLocationCoordinate2D(latitude: location.coordinate.latitude, longitude: location.coordinate.longitude) 
marker.title = "Sydney" 
marker.snippet = "Australia" 
marker.appearAnimation = kGMSMarkerAnimationPop // the error is occurring in this line 
marker.map = mapView 
locationManager.stopUpdatingLocation() 

Wie kann ich es beheben?

Answer 1

versuchen marker.appearAnimation = .pop

Answer 2

In Swift 3/4 und Googlemaps 2.3.0. Die neue Syntax ist:

marker.appearAnimation = GMSMarkerAnimation.pop
