Create native-looking iPhone/iPad applications from HTML, CSS and JavaScrip

Though it’s not widely known, you can write native-feeling iOS apps for the iPhone and iPad in JavaScript (+ HTML and CSS). If you want to put it in the app store, you can even package your web app as a “native” Objective-C app.
In this article, Matt will explain HOWTO: Create native-looking iPhone/iPad applications from HTML, CSS and JavaScript, which includes how to strip away the browser chrome (the url bar and button bar); prevent viewport scrolling and scaling; respond to multi-touch and gesture events; use webkit CSS to get the iPhone OS look and feel; cache the app so it runs without internet access; get a custom icon on the home screen; and have a splash screen load at the start.
