Is there way to limit MKMapView maximum zoom level?

by

You could use the mapView:regionWillChangeAnimated: delegate method to listen for region change events, and if the region is wider than your maximum region, set it back to the max region with setRegion:animated: to indicate to your user that they can’t zoom out that far. Here’s the methods:

- (void)mapView:(MKMapView *)mapView regionWillChangeAnimated:(BOOL)animated
- (void)setRegion:(MKCoordinateRegion)region animated:(BOOL)animated
