Further Exploration

You’ve now learned most of what there is to know about picking images and sending email, but we haven’t even scratched the surface of the Address Book and Address Book UI frameworks. In fact, the Address Book UI framework contains three additional modal view controllers. You can use the lower-level Address Book framework to create new contacts, set properties, and edit and delete contacts. Anything the Contacts application can do, you can do with the Address Book framework. For more detailed information about the use of these APIs, refer to the excellent guide from Apple iPhone OS Dev Center called the Address Book Programming Guide for iPhone OS.

In addition, review the Apple guides for Core Location and Map Kit. Using these complementary tools, you can create annotations, each with its own view, or use simple pushpin views to represent locations. On the 3G iPad, these features can be employed in full-featured GPS applications, giving your users pinpoint accuracy on a large touchable map.
