GMSMapView - how to get callback when map did end moving from scrolling

Question

I need to get a callback from GMSMapView when it stopped moving.

I have read the documentation and i have found "mapView:idleAtCameraPosition:" method, but it's not quite what i'm looking for. This method gets called too often, not just when the mapView did end moving.

Any idea?

Add a boolean to track whether the map has started being dragged. Then on mapView:willMove: set it to true. In idleAtCameraPosition, only update if this variable is true:

func mapView(mapView: GMSMapView!, idleAtCameraPosition position: GMSCameraPosition!) {
    if locationDragged == true {
        locationDragged = false
        println("changed position: \(mapView.camera.target)")
        // do stuff
    }
}
