The first 40 minutes of a longer iPhone or iPad video tutorial at CartoonSmart.com . Watch the first few minutes to find out what its about, but basically you'll learn how to add a map view into your app, show your current location define settings for it (zoom, user interactions, etc), and show your current compass heading.
In the full lesson we will then look at how to point them map at any location (a particular city), then automatically move through the city at a set speed, and the fun part will be touching areas to blow up. And areas you explode will have a crater that stays on the map and moves around as the map views (so its locked into that spot with the map). That lesson is available here...
