We’ve created a set of mobile user interface frameworks that will give you a jumpstart on creating professional, touch screen apps in Corona. In this article, I’ll show you how to add text, graphics, and custom behaviors to the List View. The List View accepts a variety of parameters. The following are the basic parameters you’ll need for this tutorial: data. A table containing elements that the list can iterate through to display in each row. default. An image for the row background. Defines the hit area for the touch. backgroundColor. Specify a table that contains R, G, B values. Example: {255, 255, 255}. callback. A function that defines how to display the data in each row. Each element in the data table will be

One of the big debates going around is whether a mobile developer should use HTML5 or go native.  Well, what if you didn’t have to make a choice? Even better, what if you could combine HTML inside a native app and still leverage the full power of OpenGL? Now you can! Just check out Corona’s web popup API which lets you embed a web view right inside your app. What this means is that you can create fluid OpenGL-based animations and combine them with HTML content, all in literally a couple of lines.  For example, here’s how you would animate an image moving diagonally across the screen, and make the bottom third of the screen open up a web page: [cc lang="lua"] local image = display.newImage(

This past Saturday, Ansca Mobile was invited to lead a Bay Area workshop on iOS and Android development with Corona. We were thrilled to show the packed house of developers (from beginners to seasoned vets) how to use the newest Corona features.  The entire Ansca Mobile team was on-hand to provide insight about the toolkit to the new class of Corona developers, and help them with their own specific coding questions afterward.  Those who stuck around until the end got to partake in some “show and tell” with their app creations — the best ones received App Store gift prizes! Thanks to everyone who came out, and special thanks to Michael P. Wang of the Silicon Valley iPhone/iPad Business Meetup group for organizing the event.

In this short video (shot and edited on an iPhone 4) we show multitouch support and physics in the form of collisions. All of this was written in Corona Game Edition by one of our developers in less than half an hour, using an upcoming library that makes any physics object draggable in one line via “touch joints”. We actually think this might be the only multitouch implementation of Box2D 2.1 — at the very least, it’s the easiest one to use! On a techie geeky note, this video was shot and edited entirely on an iPhone 4, Christopher Peri has a short write up on his blog. Download your own 30 day trial of Game Edition, and feel free to use any of our sample

We know many of you are using Corona SDK and Game Edition on both a laptop and a desktop, and having to deauthorize and reauthorize your machines manually. Now in the new release of Corona SDK at $249 and Game Edition at $349, you can authorize one primary and one secondary machine per license. You may have also noticed our new Welcome Screen that gets you started faster with documentation, sample code, and other workflow improvements. Plus we have a new icon designed by Jennifer P. Albrecht-Buehler; you can see it below or when you download the brand new Corona SDK.

Today, we remove the alpha and beta version numbers and bring you the new, cross-platform Corona SDK and a Corona Game Edition pre-release! Back in December, we released Corona for iPhone, which made iPhone app development quicker and easier than ever before without sacrificing any aspect of app performance.Using Lua, Corona took the months-long process of creating iPhone apps and shortened it into a matter of days! Almost immediately after launching that first incarnation of Corona, we set out to support multiple platforms and provide a truly versatile solution for the mobile development community. After being in the works for months, we now present to you the seamlessly cross-platform Corona SDK and Corona Game Edition: Corona SDK continues the original Corona’s tradition of straight-forward, time-efficient app

This week, not only are we launching new versions of Corona, but we’re also showing you how to use them! On Saturday, September 18, we’ll be leading a “Beginning iPhone/iPad App Development with Corona” workshop at Northwestern Polytechnic University in Fremont. Our very own CTO Walter Luh and senior engineer Evan Kirchhoff will be running the show, so rest assured you’ll be getting top-quality instruction! Be sure to check out the Meetup page for more details, including RSVP info and a list of software t0 have pre-installed before coming. Admission is $20, to cover the space rental. We only have a few more spots left, so don’t wait to reserve your spot. We look forward to seeing you this weekend!

Here at Ansca, we happily welcome the new Apple TOS relaxing the stance on third party developer tools for iOS. What does it mean to you, our current users, and for future users of the Corona SDK? It means that you can now use Corona as the development tool of choice for your cross-platform app development, for both games and non-game apps, on both iOS and Android devices. It also means that you no longer have to worry about our technology not being compliant with Apple, today or in the future. As we have done, we will continue to deliver the best development tool for app creation on iOS and Android devices. We truly believe we are delivering the fastest, easiest way to develop apps

We all woke up to an interesting announcement this morning: Apple has revised their iOS developer terms again (effective September 27), and they have now removed all the sections that previously seemed to limit development languages. In a new document called “App Store Review Guidelines”, Apple makes their intentions very clear: We are continually trying to make the App Store even better. We have listened to our developers and taken much of their feedback to heart. Based on their input, today we are making some important changes to our iOS Developer Program license in sections 3.3.1, 3.3.2 and 3.3.9 to relax some restrictions we put in place earlier this year. In particular, we are relaxing all restrictions on the development tools used to create iOS
