How can I read current zoom level of Mapbox?

Question

I have a back to home function

function panToHome(){
    latLng = [current.lat, current.lng];
    map.setView(latLng, 8);
}

I want to save the current view as history, so user can switch back as they might click mistakely. So the question is how can I know the current latlng on Mapbox?!

Answer 1

Use the getZoom method on your L.mapbox.map instance:

Returns the current zoom of the map view.

http://leafletjs.com/reference.html#map-getzoom

var mapbox = new L.mapbox.map('mapbox', 'mapbox.streets', {
    'center': [0, 0],
    'zoom': 9
});

var zoom = mapbox.getZoom();

Here zoom holds 9

Answer 2

In Android you can use

int currentZoomLevel = mapboxMap.getCameraPosition().zoom;

Answer 3

On iOS with Mapbox SDK 4.0, there's a .zoomLevel property on the MGLMapView object.
