GMSMapView animateToCameraPosition zoom in - zoom out animation

Question

I am using Google maps services in iOS (Swift) and Android. In android, the map view has a method called animatreCamera that has an animation in which the movem

I think there is no direct way you can archive the same animation in the Google Maps iOS SDK.

A workaround can use iOS's dispatch_after method, first you can define a method to delay how many seconds you want:

func delay(#seconds: Double, completion:()->()) {
    let popTime = dispatch_time(DISPATCH_TIME_NOW, Int64( Double(NSEC_PER_SEC) * seconds ))

    dispatch_after(popTime, dispatch_get_main_queue()) {
        completion()
    }
}

Then you can zoom out your camera, move to a location, then zoom in with the delay method:

delay(seconds: 0.5) { () -> () in
    var zoomOut = GMSCameraUpdate.zoomTo(kGMSMinZoomLevel)
    mapView.animateWithCameraUpdate(zoomOut)

    delay(seconds: 0.5, { () -> () in
        var vancouver = CLLocationCoordinate2DMake(49.26,-123.11)
        var vancouverCam = GMSCameraUpdate.setTarget(vancouver)
        mapView.animateWithCameraUpdate(vancouverCam)

        delay(seconds: 0.5, { () -> () in
            var zoomIn = GMSCameraUpdate.zoomTo(kGMSMaxZoomLevel)
            mapView.animateWithCameraUpdate(zoomIn)

        })
    })
}

You use your own zoom value, I use kGMSMinZoomLevel and kGMSMaxZoomLevel here.
