What To Talk About?

My iOS-related Podcast started out as “Dr. Touch Podcast” and later we rebranded ourselves to the more unique “Cocoanetics Podcast”. Though the topics always revolved around iOS development, Apple in general ans the people involved in our profession.

After an extended hiatus planning has begun to revive the podcast. I like to invite your comments, wishes and ideas as to what you would like to see – or more precisely hear – in a podcast that focusses on your daily bread and butter.

My Terminal is Less Boring Than Yours

There’s a category of developers – probably coming from other Linux-based desktops – who are feeling at home in the console (aka terminal). Especially when working with SCM systems like Git or Subversion you’re often faster committing or updating doing that via short commands as compared to Xcode.

Unfortunately Apple did not think to make the console a nice thing to look at from the get go. Let me show you quickly how you can geek up your terminal as well. Your colleagues will be impressed.

GitHub Fork, Fix, Pull Request

In this post I will to demonstrate how you can contribute to an Open Source project hosted on GitHub. I previously blogged about how you can make and apply patches, which is certainly one way. But on GitHub there is an even cooler method, one that is also less work on the project maintainer.

iPhone User Interface Cookbook

A month ago I was contacted by PacktPub with a “Review Request” and was provided with a ePub copy of the book for this exact purpose. PacktPub – which I had never heard of before – apparently is trying to get traction on the iOS developer market with a dozen books on the subject matter. But this pales in comparison to the hundreds of books they published for non-iOS ecosystems (Microsoft, Web, Java, etc.)

Is it just me or does it seem like more and more iOS developer are hoping to supplement their living from getting book royalties?

At the end of my procrastination I sat down and forced myself to read the first half of the book, taking notes to give this book a fair and balanced review. A word of caution: this will be a tragic comedy of epic proportions.

In Austria we have a saying: “Nothing is useless, it can always serve as a bad example”. It is my hope that this bad example serves to improve the overall quality of literature on our favorite subject matter.

DTCoreText – New Formula!

I chose this article’s title to try and grab your attention. Well, the product is still the same and does the same. The only difference is one that is under the hood. And as such it is your job – should you choose to accept it – to marvel at the benefits that the new old parsing engine brings us.

Taming HTML Parsing with libxml (2)

The parsing of HTML necessary for my DTCoreText open source project is done entirely with the sophisticated use of NSScanner. But it has been long on my list to rewrite all of this parsing with a the industry standard libxml2 which comes preinstalled on all iOS devices. Not only is this potentially much faster in dealing with large chunks of HTML. It probably is also more intelligent in correcting structural errors of the HTML code you throw at it.

In part 1 of this series I showed you how to add the libxml2 library to your project and explained the basic concepts of using libxml2 for parsing any odd HTML snippet into a DOM. In this here part 2 we will create an Objective-C based wrapper around libml2 so that we can use it just like NSXMLParser, only for HTML.

Helping Xcode Find Library Headers

In my previous article about Sub-Projects in Xcode I showed you how you can have an Xcode project as a dependency. The advantage of this is that you can update your library from within the same project and debug into the sub-project’s code.

One thing that was not immediately obvious was how you deal with the problem that Xcode cannot find your sub-project’s library headers. Hence this writeup.

Linguan 1.0.3

Besides fixing several bugs reported by users this release focusses on implementing a new custom-built super-charged strings scanner.

Changes

  • FIXED: missing strings file no longer aborts import
  • FIXED: added – Button for deleting tokens
  • FIXED: deletion of wrong row
  • FIXED: over-escaping of \ on writing strings files
  • FIXED: wrong token name updated on enter key
  • FIXED: search filter not reset on adding a new token
  • FIXED: Previous/Next buttons in wizard cease to function
  • NEW: replaced genstrings with high-speed custom implementation (>20x speed improvement)
  • NEW: support custom localization macro prefix

This new version does no longer support 32-bit because the new strings scanner was implemented using ARC. We hope that this does not inconvenience any of our existing uses. But then again, serious developers are on a 64 bit machine anyway since Snow Leopard…

The new version has been submitted to Apple today.
