iOS Programming 101: Intro to MapKit API and Add an Annotation on Map

A month ago, we covered how to use Core Location framework to retrieve the user’s location. We also showed you how to convert the GPS coordinate into an address. However, the best way to show a location is to pin it on map. Thanks to the MapKit API. It lets programmers easily work with the built-in Maps and pin a location.

The Map Kit framework provides an interface for embedding maps directly into your own windows and views. This framework also provides support for annotating the map, adding overlays, and performing reverse-geocoding lookups to determine placemark information for a given map coordinate.

As usual, rather than going through the theory, we’ll work on a simple app. Through the practice, we hope you’ll get a better idea about MapKit.

Let’s get started.
