This repository contains some code that can be used on iOS for some basic stuff not currently available in Apple's CoreLocation framework.
This category on CLHeading can convert a heading to its textual equivalent, e.g. 0 degrees -> 'N', 90 degrees -> 'E', etc. There are 4 levels which you can use to indicate the desired precision (N vs. NNE).
This category on CLLocation adds method to do distance calculations, as well as calculations to determine the direction (bearing) to follow to go from A to B. The methods are based on the info found at www.movable-type.co.uk/scripts/latlong.html.
