Apple’s ASN.1 OID Names

For the DTCertificateViewer component that I am presently working on I needed to have a list of all known OIDs. Those are the tags (Object Identifiers) that identify the meaning of information encoded in CER/DER/ASN.1 files.

For example OID 2.5.4.6 means “Country Name”. I was able to glean a few dozen such identifiers from looking at a variety of certificates, but I couldn’t find a complete – and localized – list of those names anywhere online. Also Apple has registered a boatload of their own OIDs like “1.2.840.113635.100.6.1.2” = “Apple Developer Certificate (Development)”.

Since I’m building this component for use on iOS and Mac it became clear that I needed to go straight to the horse’s mouth to get my strings. In this article I am going to explain how I got my list of OIDs, in all 30 languages that OS X is localized in.

Radar: Provide Warnings if App Might Crash on Devices with Previous iOS Version

On more than one occasion I’ve been stumped by some new functionality from a newer iOS version crashing when used on an older iOS device. You know, the kind of problem that you’re supposed to catch yourself with a NSStringFromClass or respondsToSelector.

The recently released Deploymate app scans your Xcode projects for such problems and flags them. This proves that such an analysis is possible and can be implemented. The developer of Deploymate confided that he hesitated to release for a long while since he feared that Apple might put exactly this functionality into Xcode. But they never did, so he created the app.

This Radar is my documented suggestion to Apple to finally add such functionality into Xcode. Worst case they should acquire the technology employed by Deploymate and add that. But I am quite certain that LLVM’s analysis capabilities should be able to put to this use as well.

Dynamic Unit Test Cases

You probably now how to add static test cases to a SenTestingKit-based unit test. You create a subclass of SenTestCase and add instance methods with their names prefixed with “test”.

When the unit test runs it builds the test classes and then introspects each one to dynamically find all such named instance methods. Those are then executed one after the other.

Usually you get by with this technique but there might be scenarios where you would want to be able to dynamically add test methods based on some external information, like a property list. Let me show you how.

Today’s Hero: CHEN Xian’an

I was having a problem in DTCoreText where the multi-byte sequence making up an Emoji would not get properly encoded by DTHTMLWriter. A quick peeking into NSHTMLWriter didn’t bring relief either, Apple is not encoding these characters, but leaves them unencoded.

Urban Airship Commander 1.1.1

Ah yes, the famous 1.1.1 version of a new app… You know, version 1.0 is always the minimally viable product. Version 1.1 lets you add new stuff that didn’t make it 1.0. And version 1.1.1 then is another layer of polish and tweaks.

Urban Airship Commander is dear to our heart and so it also deserves the benefit of a 1.1.1 version.
