I call animateWithCameraUpdate on a GMSMapView expecting it to change the map view to show the new GMSCoordinateBounds but it has no effect.
My map loads in a UICollectionViewReusableView to initially display Western Europe:
@IBOutlet weak var mapView: GMSMapView!
var fetchedResultsController : NSFetchedResultsController!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
let camera = GMSCameraPosition.cameraWithLatitude(51.48, longitude: 0, zoom: 4)
mapView.camera = camera
}
I then call a function to query all my locations and update the GMSMapView to show all my locations:
func plotAll(){
let bounds = GMSCoordinateBounds.init()
for property in fetchedResultsController.fetchedObjects!
{
let capitalAsset : CapitalAsset = property as! CapitalAsset
let marker = GMSMarker.init()
marker.draggable = false
marker.snippet = capitalAsset.address
let location = CLLocationCoordinate2DMake(Double(capitalAsset.latitude!), Double(capitalAsset.longitude!))
marker.position = location
marker.map = mapView
// Update bounds to include marker
bounds.includingCoordinate(marker.position)
}
mapView.animateWithCameraUpdate(GMSCameraUpdate.fitBounds(bounds, withPadding: 50.0))
}
My plotAll function is successfully called and loops through a dozen global locations adding these to the GMSCoordinateBounds.
But the map is not being updated. I was expecting the map view to change when I called animateWithCameraUpdate but it has no effect.
Further information, for debugging I replaced the line
mapView.animateWithCameraUpdate(GMSCameraUpdate.fitBounds(bounds, withPadding: 50.0))
with :
let camera = GMSCameraPosition.cameraWithLatitude(51.48, longitude: 0, zoom: 10)
mapView.camera = camera
This does update my map view so there is no problem with calling my plotAll function, the issue is probably in my use of animateWithCameraUpdate.
