Thus, the radius MKCircle property is read-only, which requires that any resizing be done by removing the original MKCircle from the map view and adding a new one.
To make things smoother, I add a new circle to the map view before deleting the old one.
The scaling process is quite simple in the iOS simulator, but testing on a real device leads to intermittent animation and some temporary “blocking” MKCircle color artifacts when resizing.
What can I do to make it smoother?
