Zoom programmatically using MKUserTrackingModeFollowWithHeading

Question

I want to zoom out to include the coming annotations when the map view is in MKUserTrackingModeFollowWithHeading mode.

I tried to set the scope as follows:

MKCoordinateRegion currentRegion = self.mapView.region; currentRegion.span.latitudeDelta *= 4; currentRegion.span.longitudeDelta *= 4; [self.mapView setRegion:currentRegion]; 

This reduces the scale of the 4x map, but when iOS user tracking is turned on, it automatically zooms in using animations. I can’t make any region hold on. I assume MapRect will have the same behavior, but I have not tried it.

Does anyone know of another way to do this?

According to the documentation for setUserTrackingMode:

If the map is reduced, the map display will automatically increase at the location of users, effectively changing the current visible area.

So, I understand that this may not be possible. However, the user can pinch to reduce the scale, and the user’s tracking mode remains on without changing the time. Any creative ideas are greatly appreciated.

You cannot control the zoom behavior when using the built-in tracking modes. You might want to check out something like the MapBox iOS SDK , which has the same look and behavior as MapKit, but allows you to customize this behavior.
