6.5. What You’ve Learned

In this chapter, you’ve learned how to give users access to a web app, even when they have no connection to the Internet. This offline mode applies whether the app is loaded in Mobile Safari, or launched in full screen mode from a Web Clip icon on the desktop. With this new addition to your programming toolbox, you now have the ability to create a full-screen, offline app that is virtually indistinguishable from a native application downloaded from the App Store.

Of course, a pure web app such as this is still limited by the security constraints that exist for all web apps. For example, a web app can’t access the Address Book, the camera, the accelerometer, or vibration on the iPhone. In the next chapter, I’ll address these issues and more with the assistance of an open source project called PhoneGap.
