FoodGarden – My First iOS Application

Monday, July 11th, 2011

My last post about iOS application development was based on my experiments of developing FoodGarden – a shopping list and recipe application. I will release FoodGarden via d-pointer in Apple’s AppStore, hopefully quite soon. This blog post is a short introduction for the application. Let’s watch the video first.

I wanted to keep the video short and present the most of the functionality what you can do with the app. I left the boring section out i.e. adding bunch of recipes, items and sections, which you can use when creating shopping lists and recipes.

I’ve been using FoodGarden as my shopping list application lately and it seems to work pretty well. At least I haven’t found any critical bugs or annoying features.

iOS Development from Qt Developer’s Point of View

Saturday, July 9th, 2011

I’ve been a lazy blogger lately, but it doesn’t mean that I haven’t been doing anything. Actually, I’ve done quite a lot lately. I’ve started to educate myself to iOS development. Don’t get me wrong. I haven’t changed the camp from Qt development to the iOS development, but I think it’s just a sane move to do something completely different to keep mind open and to learn new things.

As I’ve mentioned in my earlier posts, I also own Mac and iPhone, so I thought that I should try code something for iPhone. This blog post is about my thoughts what it takes to start coding on iOS operating system and what it requires if you are coming from Qt world.

DISCLAIMER: This blog post might contain errors related to iOS and Objective-C because I’m really newbie in that area. Please feel free to comment if you notice any errors in the text.

The First Challenge – Objective-C

Actually the first challenge is that if you don’t own Mac, you need to buy a new computer first because iOS development can only be done on  Mac. If you happen to own Mac, then you just need to install XCode with iOS SDK which can be downloaded from http://developer.apple.com.

The real first challenge is the Objective-C programming language. I’ve coded only using C, C++, QML, Java, Python, but never using Objective-C. The syntax looks really weird like [myObject doesSomething: parameter1 andDoesSomethingMore: parameter2]. I am also lazy in a sense that, if I need to learn new things, I get bored quite fast if I can’t try things in practice soon. Instead of starting to read Objective C manuals from Apple site, I googled a bit and found this useful document: From C++ to Objective-C written by Pierre Chatelier. That piece of paper was really useful to get fast into a Objective-C world and to understand that weird syntax.
