How do I determine if the current user location is inside of my MKCoordinateRegion?

Question

I have a coordinate region that I have determined contains the limits of what I want to show for my app. I have set this up as an MKCoordinateRegion with center point lat, longitude and a span. How do I determine if the current userLocation is inside of my coordinate region?

Use map rects. Here's an example using the map's current visible rect. With regards to your question, you could use convertRegion:toRectToView: to first convert your region to a MKMapRect beforehand.

MKMapPoint userPoint = MKMapPointForCoordinate(mapView.userLocation.location.coordinate);
MKMapRect mapRect = mapView.visibleMapRect;
BOOL inside = MKMapRectContainsPoint(mapRect, userPoint);
