Modal Info View – CommonJS Titanium Mobile Development

coding school Modal View

Hey guys!
After a long long time that I haven’t written any article I decided to start sharing little samples of code and videos from the latest technology I have learned: Appcelerator’s Titanium.
As a quick and simple review, Titanium is a framework to make native cross platform mobile and desktop applications based on JavaScript. Cool right? You can find all the necessary information to start creating iPhone/iPad/Android/MobileWeb Apps here:http://www.appcelerator.com/ and don’t forget to read the docs to have a better comprehension of what Titanium can do at: http://docs.appcelerator.com/

So let’s start with this little module based on Appcelerator KitchenSink app that what it really does is create a modal information popup, that you can use to show the user any kind of “alert” messages. This code has been tested on iPhone, iPad and Android with Ti SDK 2.0.1+.
At the moment I’m only including the chances to add some text. I’m going to add a couple of options to display and image and an native activity indicator.
Here is the modelview.js file:

/**
 * Modal Info View module - Titanium JS
 * @author César Cavazos - @cesarcvz
 * Based on:<a href="https://github.com/appcelerator/KitchenSink"> https://github.com/appcelerator/KitchenSink</a>
 */
/**
 * Open an infomation modal anywhere in hour app
 * @param {String} text
 * @param {Object} params
 */
exports.showInfo = function(text, params) {
        //TODO: Add params like images/icons
        params = (params) ? params : {};
    var infoWindow = Titanium.UI.createWindow({
        height:80,
        width:200,
        touchEnabled:false
    });
    var background = Titanium.UI.createView({
        height:80,
        width:200,
        backgroundColor:'#000',
        borderRadius:10,
        opacity:0.8,
        touchEnabled:false
    });
    infoWindow.add(background);
    var message = Titanium.UI.createLabel({
        text:text,
        color:'#fff',
        textAlign:'center',
        font:{fontSize:18,fontWeight:'bold'},
        height:Ti.UI.SIZE,
        width:Ti.UI.SIZE
    });
    infoWindow.add(message);
    infoWindow.open();
    var animationProperties = {delay: 1500, duration: 300, opacity: 0.1};
    if (Ti.Platform.osname == "iPhone OS") {
        animationProperties.transform = Ti.UI.create2DMatrix()
                                                     .translate(-200,200).scale(0);
    }
    infoWindow.animate(animationProperties, function(){ infoWindow.close(); });
};

To use this you only need to add these two lines to your code:

1
2
var Modal = require('modalview');
Modal.showInfo("This is an information modal view", { duration : 500 });

The first one can be added at the beginning of your file and the second one you should use it every time you need to send a modal information message. By default the duration of the modal is 300 ms but you can change it to whatever you need.

Here are some images:

What do you think that can be added to this little module to make it better?
