Happy iPad day everyone.

News

Great interview by Mike Prigg for the London Evening Standard with Sir Jonathan Ive about the design process at Apple.

A new app released this week which saves directly to Core Graphics Objective-C code. I would imagine the bezier curve support alone will save you the entry fee.

Tools

Until recently there was no easy way to view offline Apple developer documentation on iOS but within the last couple of months we have two cracking solutions to that problem, aren’t we lucky.

Martin Pilkington has updated his Xcode 4.3 review with a new section on user defined runtime nib attributes in Xcode 4.3. I had no idea that this existed.

I guess we all knew this deep down but Chris Lattner makes it official with a post to the Objective-C language mailing list. No more version numbers for the Objective-C language.

Code

Great clarification on why you should never interrogate an error without a failed return value by Jonathan Rentzsch and Bill Bumgarner.

Mark Dalrymple with some potentially useful code for timing blocks of code in your apps.

I love Mike Ash’s “Let’s Build …” articles, such a great idea. This week he looks at building NSMutableArray.

Design

Lukas Mathis takes an in depth look at the new UI on iPhoto for iOS. There are some definite missteps here but as he states at the end of the article, this stuff is hard and we are only just starting to tackle these complex UIs on iOS.

Louie Mantia has released a useful icon template PSD including the new iPad retina resolutions.

More Photoshop goodness, this time a collection of tips, Photoshop actions and workflows for designing for iOS.

Business and Marketing

Rian van der Merwe with an article aimed at developers making apps targeted for children, although I would suggest that this list is mostly applicable to all iOS apps.
