I am rendering a building's indoor map into MKMapView
using overlays. The building is quite small in top view. I set the desired span using
[mapView setRegion:region animated:NO];
so that building can be seen in detail.
I want to let the user zoom out and then zoom in back using pinch,
but when the user scales the map with a pinch gesture, it zooms out and cannot be zoomed in back. So I only can zoom in back programmatically calling mapView setRegion:animated:
again.
Is it possible to achieve what I want? Thanks.
