Here’s another one in our dribble of occasional mentions of the offline HTML5 alternative to building iPhone applications, just in case we ever have a problem with App Store restrictions or the need for a cross-mobile-platform deliverable enough to actually get into it:
… I’ll show you how to create an offline HTML5 iPhone application. More specifically, I’ll walk you through the process of building a Tetris game.
What am I talking about when I say “offline”? Well, it means that we have a custom icon, a custom startup screen, a native look-and-feel, and you can use the app even when the phone isn’t connected to the Internet.
The app should be as functional as it can when it is offline, just like normal native mobile apps.
This is a tutorial specifically for iPhones but most of these techniques apply to all phones that have HTML5-capable browsers…
Thorough walkthrough, easy to follow, covers offline data storage even. Good stuff, good stuff!
