Answer 1

The CoreLocation Framework provides the capability to work out the distance, in meters, between two points:

- (CLLocationDistance)getDistanceFrom:(const CLLocation *)location

You can initialize a CLLocation object with latitude and longitude:

- (id)initWithLatitude:(CLLocationDegrees)latitude longitude:(CLLocationDegrees)longitude
