Question

I got to draw a circle on my map, it has to be about 1,8 miles centered on a point.. How can I do it?

Answer 1

Basically you need to do 2 steps:

1. Create MKCircle object using circleWithCenterCoordinate:radius: method and add it to your mapView (using addOverlay: method)
2. In mapView delegate implement mapView:viewForOverlay: method, create and setup MKCircleView instance there and return it

If you have different overlay types you may need to perform some type-checks in delegate method to create overlay views appropriate for each type of overlay.
