Here’s a quick review of the most important iPhone and Mac OS X developer conferences I’ve found on the web (in no particular order). Definitely, there’s no shortage of conferences when you need information about the latest Cocoa, Mac OS X and iPhone technologies; check this out!

Apple’s Worldwide Developer Conference or WWDC, held every year [...]

… and WWDC 2009 is finally over.
This year’s event has been nothing short of amazing; maybe because not only the technologies presented blew my mind, but also because I met and spent some time with incredible guys, and getting in touch with the right people changes everything. So, to all of you, many thanks: @cigumo, [...]

(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 most [...]

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 [...]

Memory management in the iPhone is a hot topic. And since tonight I’m talking about it on tonight’s monthly meetup of the French-speaking Swiss iPhone Developers group, I might as well share some tips here from my own experience.
I won’t go dive through the basics; I think that Scott Stevenson did a great job in [...]

I’ve uploaded (yet another) update to the Objective-C REST client I’ve blogged about previously. This time I’ve scanned the code with the excellent LLVM/Clang Static Analyzer and fixed a couple of memory leaks here and there. I strongly recommend to scan your own projects with this tool, it’s extremely simple to use:

Install it somewhere in [...]

This is the talk I gave last Friday during the first edition of the iPhone Conference 2008! I hope you’ll enjoy it as much as I enjoyed giving it :)

I’ve just uploaded some code derived from the Objective-C wrapper I’ve shown in this post. You can find it in the “Projects” section, as usual and it’s simply a wrapper around the URL loading system of Cocoa, both for Macs and iPhones, providing a custom delegate protocol, so that you can handle the events raised [...]

(Highly geeky post ahead. You’ve been warned!)
I have found the very message that summarizes the beauty of Cocoa in a single word; see by yourselves, hereunder in line 47:

#import

// The interface of a person
@interface Person : NSObject {
NSString* firstName;
NSString* lastName;
int age;
}
@end

// The [...]

This is an evening project that turned out to be really cool. Let’s say that you’re a Macromedia Flash designer, and your clients ask you to bundle your nice Flash movie as a screen saver. What to do? For Windows there are free utilities to convert a SWF into a screen saver, but not for [...]
