How can I show & scroll particular bound of view for google map? other part of map we can't see and scroll

Question

I found a method for android called setLatLngBoundsForCameraTarget. But could not find for ios. Has any one idea about it? I want to scroll into particular bound. User can't scroll out of the bound which is already defined

Answer 1

I used cameraTargetBounds but not useful for me. Then I used

    func mapView(mapView: GMSMapView, didChangeCameraPosition position: GMSCameraPosition) {

    var latitude  = position.target.latitude;
    var longitude = position.target.longitude;

    if (position.target.latitude > bounds.northEast.latitude) {
        latitude = bounds.northEast.latitude;
    }

    if (position.target.latitude < bounds.southWest.latitude) {
        latitude = bounds.southWest.latitude;
    }

    if (position.target.longitude > bounds.northEast.longitude) {
        longitude = bounds.northEast.longitude;
    }

    if (position.target.longitude < bounds.southWest.longitude) {
        longitude = bounds.southWest.longitude;
    }

    if (latitude != position.target.latitude || longitude != position.target.longitude) {

        var l = CLLocationCoordinate2D();
        l.latitude  = latitude;
        l.longitude = longitude;

        mapView.animateToLocation(l);

    }
} 

And it works.
