The Sample App
The sample app for this chapter is called FavoritePlaces. It allows users to collect favorite places and view them on a map, along with the device’s current location. Users can use Core Location to geocode, or find the latitude and longitude, for an address. In addition, it can notify users when they go within a radius that they set around a favorite location. The app also provides a special location (signified with a green arrow) that can be dragged around the map to pinpoint a desired next destination; when that arrow is dropped at a location it will automatically reverse-geocode the location to display the name and address of the location.
