Swift Error - 使用未解析的标识符'kGMSMarkerAnimationPop'

Question

我收到了这个错误

使用未解析的标识符'kGMSMarkerAnimationPop'

当我在Swift 3中使用以下代码时:

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()

我该如何解决？

Answer 1

在Swift 3/4和GoogleMaps 2.3.0中.新语法是:

marker.appearAnimation = GMSMarkerAnimation.pop

在Swift 2中模糊地使用'kGMSMarkerAnimationPop'错误
