Increase maximum zoom level on MKMapView

问题

I have an image overlay on a mkmapview.

I can't seem to zoom in the image once i reach the max zoom in values of the map. I still have a lot of zooming in to the image to do.

Any ideas? Like how can i change the max zoom in value of the map?

1. you can set the zoom level from latitudeDelta and latitudeDelta.

MKCoordinateRegion region;

region.center.latitude = appDelegate.latitudeString.floatValue;
region.center.longitude = appDelegate.longitudeString.floatValue;
region.span.latitudeDelta = 0.10;
region.span.longitudeDelta = 0.10;

[self.mapLocation setRegion:region animated:YES];
