In a much needed area of training for Xcode/Mac/iOS developers, iDeveloperTV and Graham Lee have put together a modestly-priced course on Unit Testing and TDD. Unit Testing with Xcode In this course Scotty and Graham Lee help you to not only understand the mechanics of unit testing in Xcode but also show you how you might design your code to be more testable. By working through a number of examples you will initially learn how to set up unit tests within Xcode 4 and perform basic unit testing before moving on to discover how you can test parts of your code that you previously might have thought were not possible to unit test such as code that uses singletons, networks,[…]

I was looking for a very straightforward and concise definition of static variables and how they can be used in Objective-C, since I had already been using them, but only considering their usage in the context of how they are used in other languages (like C# and Java) without really thinking about their purpose and usage in Objective-C. Thankfully, one needs only look as far as the Apple Developer Library and the official guide for the language (navigate to: Objects, Classes and Messaging > Classes > Class Objects): The Objective-C Programming Language: Objects, Classes, and Messaging Declaring a variable static limits its scope to just the class—and to just the part of the class that’s implemented in the file. (Thus[…]

Apple’s Results and Developers – David Smith Yesterday Apple announced their financial results for the fiscal quarter running from October to December, 2012. The short version is that they shocked the world with record breaking revenue, profits and volume. That is all well and good for Apple, but I thought it would be interesting to boil down the numbers into the parts that actually affect individual developers.

Good editorial article from Fraser Speirs regarding Apple’s recently announced products and tools for education, and, most importantly, the iPad. Apple’s announcements further iPad revolution in education | Macworld The iPad has begun a quiet revolution in education. All over the world, schools are putting ambitious plans in place to adopt Apple’s tablet at large scale. When parents, teachers and administrators are surveyed, converting textbooks into electronic publications is often one of the main purposes that respondents imagine an iPad in school could be used for. It’s usually the parents and school administrators who are most enthusiastic about this—students and teachers often have more imagination!

This looks interesting and useful… I was considering developing something similar to create Flipboard-like effects, but this might just do the trick. FlipTransform for iOS – Cocoa Controls Animation component for the effect of flipping as in a news/clock ticker, or a page turn. Structured around the idea of a data object (i.e. headline in news, number in a clock, page in a book) as an animation frame, comprised of multiple CALayers.

I haven’t been writing a bunch of topics lately about web design but this one caught my eye: Top Minimalist Website Designs: Trends and Examples » Color, Layout » Design Festival When you think of minimalism, you may conjure up images of black and white color schemes, overly-??simple layouts, maybe a splash of color here and there. The actual concept in context of web design is about stripping out anything unnecessary. While this can produce boring design, there is a LOT of creative freedom within this framework. Seems like the principles apply to other areas (read: “app design”) as well. Thanks to SitePoint for the referral, and thanks to Design Festival for the content…

Great article on the importance of design at this point in time, showing just how crucial a design focus is to succeed. A List Apart: Articles: An Important Time for Design Design is on a roll. Client services are experiencing a major uptick in demand, seasoned design professionals are abandoning client work in favor of entrepreneurship, and designer-co-founded startups such as Kickstarter and Airbnb are taking center stage. It’s becoming increasingly difficult to ignore the fact that design has a massive role to play in the evolution of the web and the next generation of web products. This has not gone unnoticed in the startup world. Nearly every CEO and VC I’ve met in the last six months is on[…]

iBooks 2 hands-on: Apple’s reinvented textbook | The Verge As for Life on Earth itself, it runs extremely well even on the original iPad we tested it on. Movies load quickly, page turns are smooth, and embedded animations work without a hitch. Images are particularly engaging, as most go full-screen with a tap, and also contain a number of other related images to swipe through as well. The download process was slightly painful, but that could be due to a large number of people hitting Apple’s servers all at once.
