This is useful for things like a password field. However, you will notice that the keyboard icon that lets you choose languages is absent. This means that … [READ THE FULL ARTICLE]
Java has a very useful class called the BlockingQueue. With a blocking queue, the dequeue operation will block until there is something to be dequeued. A blocking queue is very handy and can be used to solve the classic producer-consumer problem. I needed a similar class in Objective-C, but I could not find one. The … [READ THE FULL ARTICLE]

Rigid Body and Soft Body Physics This is the first of a 4 part series which will show you how to simulate a simple soft body physics object in Box2d. We will be attempting to draw a fully texture mapped, squishy object. In part 1, I will be constructing the physics object. Box2d is a … [READ THE FULL ARTICLE]
Cocos2d and OpenGL Cocos2d hides most of the complexities of OpenGL, but every now and then you will be forced to write some custom OpenGL code. You can override the draw method of CCNode to perform your custom OpenGL drawing. You don’t have to write the code for scaling, rotating or translating inside the draw … [READ THE FULL ARTICLE]
