Framework mimics native apps using HTML, CSS
Further investigation uncovered an entire framework consisting of 4,300 lines of code, with each class and constant prefixed with the letters "AD" and contained in a file labeled AdLib-ug-ipad.js.
"The framework looks to be extremely well thought out and complete," Hoskins says. "Perhaps this will be a framework to support a future release of Dashcode, an application for writing dashboard widgets and Safari/iPhone web apps."
Apple has yet to disclose the framework or offer documentation. It is unclear if the code will be announced as part of the upcoming iPhone OS 4 event.
