This week a new version of iCapital got released in the App Store. It was my guinea pig app to learn myself Objective-C this summer when I broke my foot. It was an excellent learning app, because it covered a lot of new concepts which I had to tackle:
Migrating data on updates
Now, 8 months later, I took a look at how I left my code behind in my repository and I thought it was a good thing to rewrite the whole app as I now have a much better understanding of the language. Since then I created a new game Boring Meeting OXO, an iPad app (in a private store, but you can take a look how it works here, this was still in a development phase), and a few personal apps. As I feel myself comfortable with the language now, I hope I can release many new apps soon (one is coming pretty soon :-)!
As with every update, I give away some promo codes you can redeem via the App Store. So for the quick readers, here are 10 promo codes:
When you release an app and add new features, there will be a time you need to update you persistent store. This is easy to do when you are in a development stage, because you can just delete your app and the persistent store will be re-generated. But when you are live and people have downloaded your app, you need to be careful. They won’t like it if suddenly their saved data has disappeared!
After finishing up iCapital, I was thinking about a new app to learn some extra API’s or frameworks. We were discussing about games during meetings, and that was my eureka moment. You probably know the feeling when you are in a boring meeting and you want to play OXO with a collegue … passing the paper and thinking ‘oh damn, it’s so obvious we aren’t paying any attention’.
Due to a broken foot this summer, I finally found the time to investigate the objective-c language.
As a result of this, I’ve just released my first app to the App Store … iCapital!
It’s a little app which let you search for any country in the world and it will tell you what the capital is. You can also do an inverse search (so if you know the capital and you want to know the country). If you want additional data, the app connects to Wikipedia!
