libanim: animated textures and images for iPhone/iOS

Thursday, August 12th, 2010

I recently started a new project called libanim (home page)¬†which aims at providing support for animated file formats on the iOS and perhaps Android at a later stage. The problem doesn’t seem to be limited to any one platform, support for animated file formats is usually limited to gif files but on some places (e.g. […]


Disabling multitasking on iOS 4 apps

Tuesday, July 27th, 2010

If you’re using the iOS 4 SDK then by default your app will be assumed to support multitasking even though you actually need to add support for it and you might not have done that (e.g. updating an old application). While multitasking seems nice it isn’t always the best scenario for your app, specially when […]


The little evilness of @property

Wednesday, April 21st, 2010

One of the special enhancements Objective C adds to basic C/C++ is the ability to declare and use properties with a simple and straightforward usage.

I think, as a publisher and occasional AdMob advertiser, that […]


An introduction to game physics with Chipmunk

Wednesday, May 6th, 2009

During the past week I’ve been writing a tutorial about Chipmunk, a physics engine very popular among 2D games. The article’s focus is mainly for the iPhone but the Chipmunk code itself is portable to any platform because it’s pure C. I’m thinking about giving the new preview of Monodevelop for OS X release a […]


Calling Code In A Different Controller With Objective-C

Thursday, November 27th, 2008

I’m fairly new to the Objective-C and it might not come as a surprise that I’m only learning it because it’s the default iPhone programming language. What geek owns an iPhone and didn’t at some point want to create its own application? Well for me it’s not just for the personal pleasure, it also my […]
