How can I add a radius to a CLLocation coordinate? What I want is to see what clients are near a specific coordinate.
What I need is to add 2000 meters, or 2km to a coordinate.
How do I do that?
You can’t “add a radius” to a coordinate. What you can do if you have
CLLocationobjects (say loc1 and loc2), is calculate the distance between them:and see if dist (which is in meters) is more or less than 2000.0.
Converting between coordinate latitudes/longitudes (which are polar coordinates) and distances is complicated, which is why the SDK provides you with this functionality.
