Change GMSCameraPosition zoom (iOS)

Question

I want to change GMSCameraPosition' zoom programmatically (Google Maps iOS SDK).

I tried to change:

mapView.Camera.Zoom=11;

but it's a "read-only" property and "setZoom:" does not exist.

How can I do that?

Answer 1

There is different way to do that.

You can use -animateToZoom: on your GMSMapView, or you can create a GMSCameraPosition and set the coordinate and zoom level and then use -animateToCameraPosition: or create a GMSCameraUpdate and then use -animateWithCameraUpdate:

GMSCameraPosition *cameraPosition = [GMSCameraPosition cameraWithLatitude:latitude
                                                                longitude:longitude
                                                                     zoom:11.0];

[self.mapView animateToCameraPosition:cameraPosition];

or

GMSCameraUpdate *update = [GMSCameraUpdate zoomTo:11.0];
[self.mapView animateWithCameraUpdate:update];

or

[self.mapView animateToZoom:11.0];

Hope it helps.
