DTXMLRPC for Posting to WordPress

Mar 22, 2013

On Fridays I like to do something fresh. Today I wrote an XML-RPC framework. The reason for doing that is that I love Amy Worrall’s QuickRadar.

Since I am trying my best to file good bug reports I spend much time on them. Being economically minded I like to reuse the same content I produce as much as possible. So when I file a Radar with QuickRadar I post to Apple’s bug report, to OpenRadar, share the link on App.net and on Twitter. What was missing in my opinion was to also get the text of the bug report into a new WordPress blog post.

Using Custom Fonts with DTCoreText

Mar 20, 2013

Friend of DTCoreText Holger was having problems getting DTCoreText to use the bold font face of his custom font.

I want to take this opportunity to explain what the root cause for Holger’s problem was and what you need to know if you’re using custom fonts with DTCoreText.

Localization Unit Test

Mar 19, 2013

It happens to the best: you add new features to an app localized in several languages. You are not the lazy type that names the NSLocalizedString key’s the same as the English-language strings. Instead you name the keys semantically, like DOWNLOAD_ALERT_MSG.

Then when it comes to shipping you send the client a note that there are some new strings and assume that he will be able to find out which are new and need to be translated. Which he would if he was using a tool like Linguan. Which he is not, because you might have forgotten to recommend it to him, or if he’s extremely unlucky then he’s a Windows user.

Apple’s ASN.1 OID Names

Mar 17, 2013

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

Mar 16, 2013

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.
