with small animation fix.

class MapViewZoomCenter: MKMapView {

    var originalRegion: MKCoordinateRegion!

    override func awakeFromNib() {
       self.configureView()
    }

    func configureView() {
        isZoomEnabled = false
        self.registerZoomGesture()
    }

    ///Register zoom gesture
    func registerZoomGesture() {
        let recognizer = UIPinchGestureRecognizer(target: self, action:#selector(MapViewZoomCenter.handleMapPinch(recognizer:)))
        self.addGestureRecognizer(recognizer)
    }

    ///Zoom in/out map
    func handleMapPinch(recognizer: UIPinchGestureRecognizer) {

        if (recognizer.state == .began) {
            self.originalRegion = self.region;
        }

        var latdelta: Double = originalRegion.span.latitudeDelta / Double(recognizer.scale)
        var londelta: Double = originalRegion.span.longitudeDelta / Double(recognizer.scale)

        //set these constants to appropriate values to set max/min zoomscale
        latdelta = max(min(latdelta, 80), 0.02);
        londelta = max(min(londelta, 80), 0.02);

        let span = MKCoordinateSpanMake(latdelta, londelta)

        self.setRegion(MKCoordinateRegionMake(originalRegion.center, span), animated: false)

    }
}
