    Very interesting. First you need to have a UIView covering up your Map, You need to use CLLocationManager for location updates, now translate location coordinate to the UIView pixels which will give you position of current location according to coordinates, when you get the point you need to erase the view with a radius around point just like a paint brush works. This problem has very long answer I just gave an idea you can start by this idea. – iphonic Feb 15 '17 at 11:27
