I'm not using this for driving directions or similar. I have a few annotations and want a trigger when user is in the vicinity of one of those, so I can alert the user.
It seems didUpdateToLocation is called only once per startUpdatingLocation call? At least when I NSLog within that method, I only get one line in console. No, I'm not walking around with the iphone.
So: What is the correct way to set up a continuous monitoring of userLocation and get a "callback" (either when 3-4 seconds have passed or when user has moved say, 10 meters)?
