DTMorseKeyboard Tutorial

Apr 01, 2012

Inspired by the Gmail Tap April Fools joke by Google I felt inspired to program the same thing for iOS. There we have custom input views as well as the UIKeyInput protocol and so I figured it should be an easy undertaking.

The whole affair took slightly more than one hour and I was hoping to record it in 1 second intervals with ScreenNinja. Unfortunately it seems that this otherwise fabulous app crapped out on me. I later discovered that the MOV file had actually finished before the crash, so to my delight (and hopefully yours too) you can follow this tutorial on YouTube.

OMG! SocialGate!

Apr 01, 2012

I was already packing my suitcase for my vacation next week when I learned about the makings of the biggest scandal that is about to happen on the Apple campus. And I am not talking about AntennaGate or WarmGate, this is a REAL scandal! I just had to sit down and document the facts – as we know them so far.

A source close to the matter informed me (on condition of anonymity) that Apple CEO Tim Cook has set a plan in motion that will – so he fears – dramatically tarnish Apple’s reputation and throw them back to the technological stone age … at least when it comes to social media.

UDID … or Didn’t U?

Mar 30, 2012

Developers all around are struggling to update their ad network libraries as a reaction to rumored app rejections. It has been reported that apps which access the unique device identifier are getting semi-randomly singled out.

But, in light of recent revelations this apparently is not entirely true. Here’s a quick rundown of what is actually happening and what companies seem to be beginning to agree that the best solution is going forward.

Beware of NSString Optimizations

Mar 29, 2012

There are some scenarios where NSString acts as a class cluster internally to optimize handling of certain strings. One such case bit me today, and so I want to tell you about it.

Class clusters work such that you think you are always dealing with just instances of NSString, but in reality the runtime goes and chooses different subclasses for certain tasks. You might have already seen some effects of this behavior when debugging and the debugger actually showing you something other than NSString as the type of a variable.

DTCoreText Feedback

Mar 28, 2012

Always lovely to get Feedback for my work. Here’s a nice e-mail I got from Mustapha Ben Lechhab, a freelancer, who is successfully using DTCoreText to display arabic rich text and an embedded audio player.

DTCoreText lets you easily render HTML text (via NSAttributedString) in your apps without having to use UIWebView. The cool feature this guy used was that you can easily embed your own custom UIViews in the text, for playing an audio or video file.

In his own words …

iWoman 2.0.6

Mar 28, 2012

I thought I was smart when refactoring some code in DTAboutViewController to use block-based animations. Turns out that I had not considered backwards compatibility for 3.x when doing that simple change. This caused some unlucky users (still on iOS 3.1.3) to get the update pushed via iTunes, but then finding themselves unable to launch the app.

I do plan to cease supporting 3.x sooner or later, but not like this. The proper way is to raise the deployment target when implementing features that require 4.x. This way people unwilling (or unable) to update their devices just won’t be receiving those new updates but will still be able to continue using the old version.

Changes

Fixed: Incompatibility with 3.x causes app to crash
Added: Alert when user tries to send support e-mail but has no account configured
Fixed: Tapping on today button in cycle view would show the wrong day in cycle view.
Fixed: Tapping on the calendar button in Wheel View would lead to the wrong day in calendar view (in some time zones)

The update has been submitted to Apple and should be available soon.

Update April 4th: … the update is now available on the App Store.

NSConference 2012 Wrapup

Mar 24, 2012

I attended my first NSConference this year after grabbing the first ticket that became available to people on the waiting list. The conference had sold out in record time before I was able to make a decision. So I jumped at the chance when they gave me a second chance.

NSConference is held annually in Wokefield Park in the middle of a golf course. Scotty, the conference host, informed us that the reason for this is simply to force the 200 attendees to network amongst each other if only because you cannot easily drive to town.

After the conference we were asked to provide feedback via e-mail, but I am a firm believer doing so publicly because this enables the valued reader to form his own opinion and whether he should attend NSConference 2013.
