JyOS - Native iOS Apps written in JavaScript with Visual Studio on Windows

What is JyOS ?

JyOS is a JavaScript v 3 runtime for iOS (iPhone, iPod and iPad) with a specific limited API to write data-centric native app. The development platform is Windows and the preferred IDE is Visual Studio 2010 or Visual Web Developer Express (free). You can also develop with other text editors and any operating systems with a text editor and a ftp program. JyOS has nothing to do with HTML5 or PhoneGap. JyOS is JavaScript using the iOS API natively.

Current State Of JyOS

After feedbacks in october 2012, I concluded the following:

Titanium would always be a better solution on multiple platforms that everything I could build by myself on iOS only.
I would have to reduce greatly the app features to be able to published it to the App Store.

So I decided to put JyOS on hold and focus on a first app written in JyOS named jsonB which is avalaible on the app store.

Hello World

/*
    Hello World Sample
 */

JyOS.App.Name = "Hello World App 0";

var mainTableView = new JyOS.TableView("mainTableView", "Hello World");

mainTableView.init = function () {

	this.addSection("JyOS - JavaScript For iOS");
    this.addData({ Type: STRING, Id: 'HelloWorldControl', Value: 'Hello World' });

    this.click = function (control) {

        alert("Hi " + control.Id);
    }
}
function main() {

    JyOS.open(mainTableView);
}
