Useful UIImage category for handling sprite sheets. This add-on smoothes the way of extracting images from a sprite sheet (texture atlas).
This can be useful in UIImageView animations where animationImages array has to be filled with a set of images representing frames. UIImage-Sprite category makes this process trivial…

The basic trick is to get a CGImageRef with CGImageCreateWithImageInRect you then ...]]> http://www.alexcurylo.com/blog/2012/02/03/uiimagesprite/ Cocos2d for iPhone 1 Game Development Cookbook

…So how do we achieve loose coupling in our own code? Well, at first, we need to get a better idea on the current coupling. Let us define class dependancy: class A depends on B iff class A imports class B header. With such a definition, we can draw a graph of dependancies between classes by considering the Objective-C #import directives in ...]]> http://www.alexcurylo.com/blog/2012/01/10/dependency-graphing/ rsebbe / CeedMath

We’d particularly like to draw your attention to this bit, what happened after he decided to implement them:

… So I sucked it up and submitted 4.0 with the auto-renewing subscription and the complex server-side code to support it.
It was rejected. I was told via phone about an apparently unwritten rule that I was violating: auto-renewing subscriptions can only be used ...]]> http://www.alexcurylo.com/blog/2012/01/08/autorenewable-warning/
