No surprises here but Apple have confirmed their annual iTunes Connect shutdown at the end of December. All the usual rules apply and you shouldn't be scheduling updates or price changes during that time unless you want your app to disappear for a few days.

Blake's iOS Device Specification Grid
iOS is over 5 years old now and as more devices get released it can be hard to keep track of the hardware inside them. Blake Patterson has put together a handy table of all the (known) hardware for all currently released iOS devices. As someone who has had search for these kind of facts and figures before some of this information is surprisingly hard to find so this is going on my permanent list.

iOS Support Matrix v2.0 - Winter 2012
On almost the same subject, Richard Stelling takes a more iOS version focused look at the same problem with an update to his iOS version support matrix PDF. I wouldn't usually link to two things which are so similar in the same issue but both of these tools contain super useful information.

Caching Drawing Code
Interesting idea from David Keegan to use a tool like PaintCode to generate drawing code which is then cached to bitmaps at runtime in an attempt to try and reduce the ever increasing size of our app bundles (amongst other things) while retaining efficient rendering.

A New Mobile UX Design Material
Not being involved in much animation before coming to iOS development I hadn't heard of Disney's 12 principles of animation before reading this wonderful article by Rachel Hinman for Smashing Magazine. The article goes through all of the relevant principles with examples from mobile apps. If you read one post from this week's issue, make it this one.

Bringing Responsiveness to the App World
Still my favourite text editor for writing, iA Writer for Mac had a new release this week. Oliver Reichenstein talks about resisting the temptation of taking every feature request and adding it to a to-do list and it is rare to see this level of thought over a feature like this. This article is not spceific to iOS development but the techniques and discussion should still be interesting.
