The more advanced programmers among you might know the concept already: technically they are called closures, and were first introduced in the Scheme language in the early 1970′s. Many languages since then have had support for them in one form or another, including Smalltalk, Objective-C’s ...

In this tutorial you get to take a look at how to create multiple views and make the touched view follow the users touch. We also take a look at the simple affair of creating a view in code (programmatically).

Beautiful collection of iPhone wallpapers
In the search of a nice iPhone wallpaper I’ve always been frustrated by the fact that, while looking great, they were mostly designed neglecting the lock screen UI boundaries, and the main subjects ended up being covered by the time and unlock areas. One day, after weeks sketching on a notepad simple minimalist objects with no specific purpose (and in portrait oriented rectangles!!) I realized the two things were matching and started designing the first one, Raindrop. It looked pretty ...

Create your first iPhone ‘Hello World’ application
I’ve recently taken it upon myself to get into iOS development.

iPhone 4 GUI PSD (Retina Display)
Thanks for you patience on this one. It took a good deal longer to complete given the sheer size and level of detail the retina display has. It wasn’t a simple scale-up from the last file. It was clear as we created it that Apple has spent a lot of time considering how each element should be translated to such a dense resolution.
