This document summarizes a presentation about building native mobile apps using JavaScript with Titanium. The presentation covers Appcelerator and how it allows JavaScript code to be compiled to native iOS and Android apps rather than web views. It also discusses Titanium's SDK and cross-platform APIs, Alloy's MVC framework for Titanium, and Hyperloop which allows accessing any third party APIs from JavaScript. The slides from the presentation will be shared on Twitter the next morning.

16. Hello World
var window = Ti.UI.createWindow({
backgroundColor: “white"
});
var label = Ti.UI.createLabel({
text: “Hello World”
});
label.addEventListener(“click”,
function open() {
alert(“Hello World”);
}
);
window.add(label);
window.open();
Ti API

17. Ti.createMyFartApp()
Ti.UI.createX() // Cross-platform UI View factories
Ti.UI.X // The UI View proxy the factory creates
Ti.UI.iOS.X // Platform specific UI View factories
Ti.X // Cross-platform device APIs
Ti.Android.X // Platform specific device APIs
require(“ti.map”).X // CommonJS & Titanium Modules

25. What happens to your XML and TSS?
<Foo>
<Foo ns=“Ti.bar”>
<Foo module=“bar”>
<Require src=“foo”>
<Widget src=“foo”>
<Foo id=“bar”>
<Foo bar=“zoo”>
“#bar”: {
color: “white”
}
Ti.UI.createFoo();
Ti.bar.createFoo();
require(“bar”).createFoo();
Alloy.createController(“foo”)
.getView();
Alloy.createWidget(“foo”)
.getView();
$.bar = Ti.UI.createFoo();
Ti.UI.createFoo({
bar: “zoo”
});
$.bar = Ti.UI.createFoo({
color: “white”
});

26. A lote more..
• Platform specific code blocks and assets
• Platform/Environment specific config file
• Underscore + Moment.js: built-in libraries
• Backbone.js: events, models and data-binding
• Alloy Themes: Ideal for white label apps
• Alloy Widgets: Re-use code across apps
• …

var blur =
require('bencoding.blur');
var view =
blur.createBasicBlurView({
blurRadius: 5,
image: '/images/background.png'
});
var window = Ti.UI.createWindow();
window.add(view);
window.open();
How you used to extend Titanium

30. Hyperloop for Windows
var Window = require('Windows.UI.Xaml.Window'),
TextBlock = require('Windows.UI.Xaml.Controls.TextBlock'),
Colors = require('Windows.UI.Colors'),
SolidColorBrush =
require('Windows.UI.Xaml.Media.SolidColorBrush');
var text = new TextBlock();
text.Text = 'Hello, world!';
text.FontSize = 50;
text.Foreground = new SolidColorBrush(Colors.Red);
var window = Window.Current,
window.Content = text;
window.Activate();

31. 
var Hyperloop = require("hyperloop");
var TiApp = require("TiApp");
var UIViewController = require("UIViewController");
var UILabel = require("UILabel");
var UIColor = require("UIColor");
var UIScreen = require("UIScreen");
var CGRect = require("CGRect");
var NSTextAlignment = require("NSTextAlignment");
var label = UILabel.initWithFrame(CGRect.Make(0, 0,
UIScreen.mainScreen().bounds.width,
UIScreen.mainScreen().bounds.height
));
label.setText('Hello World!');
label.setTextColor(UIColor.redColor());
var viewController = UIViewController.init();
viewController.view.setBackgroundColor(UIColor.whiteColor());
viewController.view.addSubview(label);
TiApp.app().showModalController(viewController, false);
Hyperloop for iOS

32. 
var Hyperloop = require("hyperloop");
var TiApp = require("TiApp");
var UIViewController = require("UIViewController");
var UILabel = require("UILabel");
var UIColor = require("UIColor");
var UIScreen = require("UIScreen");
var CGRect = require("CGRect");
var NSTextAlignment = require("NSTextAlignment");
var label = UILabel.initWithFrame(CGRect.Make(0, 0,
UIScreen.mainScreen().bounds.width,
UIScreen.mainScreen().bounds.height
));
label.setText('Hello World!');
label.setTextColor(UIColor.redColor());
var viewController = UIViewController.init();
viewController.view.setBackgroundColor(UIColor.whiteColor());
viewController.view.addSubview(label);
TiApp.app().showModalController(viewController, false);
Hyperloop for iOS

33. Hyperloop for Android
var TextView = require('android.widget.TextView'),
Activity = require('android.app.Activity'),
Color = require('android.graphics.Color'),
RelativeLayout = require('android.widget.RelativeLayout'),
Gravity = require('android.view.Gravity'),
TypedValue = require('android.util.TypedValue');
var text = new TextView(activity);
text.setText("Hello World!");
text.setTextColor(Color.RED);
text.setTextSize(TypedValue.COMPLEX_UNIT_PX, 60);
var layout = new RelativeLayout(activity);
layout.setGravity(Gravity.CENTER);
layout.setBackgroundColor(Color.BLACK);
layout.addView(text);
var activity = new Activity(Ti.Android.currentActivity);
activity.setContentView(layout);

34. var text = Ti.UI.createLabel({
text: "Hello, world!",
font: {
fontSize: 60
},
color: 'red'
});
var window =
Ti.UI.createWindow();
window.add(text);
window.open();
Abstraction can be good
