The document provides an overview of using MapKit, a framework introduced in iPhone 3.x, which allows developers to embed maps in their applications using Google map tiles. It discusses key classes such as MKMapView and MKAnnotation, customization of map annotations and pins, handling geocoding, and managing map data effectively. Additionally, it highlights legal considerations, alternative mapping options, and resources for further learning.

- 2. Why Maps? • iPhone is a mobile / pocket computer • Where am I? • How do I get somewhere? • What’s near me? Julio Barros E-String.com
- 3. Dark ages (pre 3.0) • Static map images • Web view with Javascript shenanigans • Exit out to google maps Julio Barros E-String.com
- 4. MapKit • New in iPhone 3.x • Embed map in your app • Uses Google map tiles • Familiar map UI Julio Barros E-String.com
- 5. Important Classes MKMapView MKAnnotation (protocol) MKAnnotationView Julio Barros E-String.com
- 6. Important Classes MKMapView MKMapViewDelegate MKAnnotation (protocol) MKAnnotationView MKPinAnnotationView Julio Barros E-String.com
- 7. Simplest Example • MKMapView ... just a view • Or use Interface Builder • Don’t forget to add mapkit framework Julio Barros E-String.com
- 8. That was easy Julio Barros E-String.com
- 9. Show User Location Julio Barros E-String.com
- 10. Showing a particular area on the map Latitude Span Center “best fit” not exactly what you set Longitude Span Julio Barros E-String.com
- 11. Regions • MKCoordinateRegion Julio Barros E-String.com
- 12. Denver, Colorado Julio Barros E-String.com
- 13. Demo data plist of Brewery information: name, address, latitude, longitude Julio Barros E-String.com
- 14. Loading Demo Data Julio Barros E-String.com

- 16. MKAnnotation Julio Barros E-String.com
- 17. MyAnnotation Class Julio Barros E-String.com
- 18. Adding Annotations Julio Barros E-String.com
- 19. Default Pins at annotations Julio Barros E-String.com
- 20. Customizing pins • MKPinAnnotationView • MKMapViewDelegate - set a delegate Julio Barros E-String.com
- 21. Our purple pins Julio Barros E-String.com
- 22. Custom markers • MKAnnotationView Julio Barros E-String.com
- 23. Customizing the view Julio Barros E-String.com
- 24. Customizing the Callout Julio Barros E-String.com
- 25. Tapping the call out view Julio Barros E-String.com
- 26. Reverse Geocoding • Geocoding : address to coordinates • geocoder.us other services • Reverse geocoding : coordinates to address Julio Barros E-String.com
- 27. MKReverseGeocoder Julio Barros E-String.com
- 28. MKPlacemark • Address info including, country code, country, postal code, administrative area, sub administrative area, locality, sub locality, thoroughfare, sub thoroughfare • Conforms to MKAnnotation • Has address dictionary with Address Book keys Julio Barros E-String.com
- 29. Number of pins • Try to limit annotations to ~100(?) • Implement region change delegate methods • Create and manage your own clusters Julio Barros E-String.com
- 30. Challenges • Anchoring an object to a location on the map and having it scale. • Shapes - neighborhoods • Lines - routes / paths • View space to Geo Space - (CGPoint)convertCoordinate:(CLLocationCoordinate2D) coordinate toPointToView:(UIView *)view - (CLLocationCoordinate2D)convertPoint:(CGPoint)point toCoordinateFromView:(UIView *)view Julio Barros E-String.com
- 31. Legal limitations I’m not a lawyer but think carefully before using this for: vehicle/fleet tracking routing cacheing tiles geocoding / mass reverse geocoding Read the TOS http://code.google.com/apis/maps/iphone/ terms.html Julio Barros E-String.com
- 32. Possible Options • OpenStreetMap.org (OSM) - map/tile data • Route-Me - OSS map view • Cloudemade.com - services around OSM • geocoder.us (among others) Julio Barros E-String.com
- 33. Resources • MapKit Framework Reference - Apple • Using Map Kit with Bill Dudney - PragProg • Using Map Kit ... Bill Dudney - Wednesday Julio Barros E-String.com
