A really short post today that gathers Dan’s presentation at TiConf 2013 where he talked about optimizing the code in order to speed up Titanium Appcelerator apps.

This will probably be the last blog post for 2012 and I don’t want to end this year and begin another one without sending an invitation to all Titanium Appcelerators DeveLovers out there to come and meet each other at TiConf 2013.

Let’s meet next February 23th in Valencia (Spain), have a drink and chat about Titanium, NodeJs, SQL Lite, your latest Android phone, the latest SDK available or the last night’s tapas tour. Whatever makes you happy, just come – spring in Valencia is awesome and there will also be plenty of time to tour the city and its bars too.

The presentation is in Spanish and I am also attaching the slides, just in case.

The slides of the presentation

Today I will try to talk about my experience as a freelancer that uses Titanium for all his mobile projects and how to build your career around the community.

After Appcelerator launched the Marketplace I managed to create and post an iOs only module that is able to create QR codes directly on the device without using an online service.

It can generate all types of codes (from 1 to 40) and with any level of correction (L, M, Q, H). You can also customize the size of the resulting QR code and it will try to adapt itself to this size to remain perfectly sharp and fully visible.

Most of the devices nowadays are equipped with an accelerometer that detect the orientation of the device or the movements the user is doing with it.

Titanium exposes this functionality through its APIs so let’s take advantage of that

Dan Tamas was invited to talk about Titanium Appcelerator at TheEvnt 2011 in Cáceres, Spain, May 14th and the purpose of this talk was to present the advantages of using this framework to develop applications for iPhone, iPad and Android devices.

It was an introductory talk in order to present to the Spanish developers an alternative to ObjectiveC and the very popular Java.

Titanium Appcelerator Mobile has implemented for iOs the Bonjour (or ZeroConf if you want) network protocol that allows you to connect to another device found in the same network.

Before starting with the boring part – I mean the code – let’s watch a video with a small demo showing 3 devices playing together

Networking with Titanium Mobile on iOs

Almost any UI element can be animated and transformed, allowing you to add to your application some eye candy or simply take advantage of predefined elements to give them a new role. For those familiar with CSS3 animations this will come very easy as the concept it’s pretty the same.

Animations

Pointless to say, an animation will change one or more properties of an element form the current stage to another (set by us) in a period of time.

This doesn’t need any kind of introduction. You can use the location on the devices to find the user’s place and act accordingly. One thing good to know is that this needs the approval of the user, and for iOs > 3.2 you need to set a purpose property to let Apple know what you need it for.

Titanium.Geolocation.purpose = "GPS user coordinates";

How geolocation works?
