Now that the NDA on the iPhone OS 3.0 SDK has been lifted (which happened much faster than what I thought it would take!) here’s my first contribution to the world of iPhone OS 3.0 open source code: sample code about how to use OpenGL ES 2.0 on the iPhone 3GS, something I announced in [...]

(Somehow this project seems to me so simple, that I’m sure someone has done this before. Anyway). This is my feeble attempt to bring an answer to the eternal dichotomy between those arguing about the relative benefits of creating user interfaces via Interface Builder or via pure Objective-C code: let me introduce nib2objc. Unbeknown to [...]

Finishing my series of copied flattered UIs, like that Facebook thingy or that Twitterriffic gadget, here’s Apple’s own iPhone keyboard, in a really sloppy implementation that has been blatantly and horribly copied, with awful sounds that pop when you tap the numbers and such. The Fring iPhone application uses a similar keyboard, but with a [...]

This is one of the most common scenarios for network- + UITableView-based applications; a UITableView instance whose contents come from the network; not only the text, but also the images! Somehow we all want to reproduce the behavior of the App Store (or of the iTunes) iPhone application, where the icons (or covers) of the [...]

They say imitation is the best form of flattery. Well, here’s another attempt at doing that, after my “attack” on the Facebook iPhone app (decidedly I’m on a somewhat copying mood lately). I use Twitterriffic a lot, both on the iPhone and on my Mac, and particularly in the iPhone version, I’ve always liked the [...]

No, not a comic strip nor anything else that uses the “strip” word. But rather this component which lately has appeared in many different iPhone applications (see below some screenshots from the Facebook, the LinkedIn and the TSRinfo ones), and which I simply reimplemented, and then posted the code to Github for everyone to enjoy [...]

This is something I’ve been looking forward to do for some time. After praising git back in 2007, now I’m moving many of my personal projects to Github, which has an absolutely brilliant service! For the moment I’m using the free account, but I will most probably switch to a paid account soon. The only [...]

If you haven’t tried git, you should. Git is a “distributed version control” system, that is, similar to Subversion with the big difference that… you do not need a server. There are only clients, any of them, and you can pull and push changes to and from other repositories from your project colleagues. The git [...]
