To translate or not

June 4th, 2012 posted in Objective-C

Creating a lot of apps have taught me some important lessons.

One being also keep in mind that you may have to translate your app.
I tent to use NSLocalizedString for every string I write in code just so that when its needed I can easily translate the app. Which has been a time saver many times.

I don’t really use the multilingual NIB (adding localised versions of NIB files). Because, especially in early stage if development, you have to maintain two or more files. I just do it in code and adjust the UI if needed.
Getting the size of a string is fast en easy.

Well this isn’t always the case, especial if you want to keep support for those device that can run iOS 4.*. Luckily there is an easy solutions for this.

JSON parsing

August 23rd, 2011 posted in Web technology

Many people have written about parsing JSON data on the iPhone, but why use JSON and not XML.
Well this has to do with overhead, JSON is smaller in it’s mark-up then XML thus it will take less traffic on the cellular network.

But there are some drawback in using JSON, since there is no real strict way of checking the model. Like DTD is for XML.
