Show HN: I'm releasing a series of OS iOS/Mac apps to show how they're built

40 points by oscardelben ↗ HN
I'm a iOS and Mac developer and the thing that mostly bothered me when I first started learning Cocoa programming was the lack of full featured sample code.

Now things have changed and more projects have been released, but I still want to do my part.

I've already released Color Picker Pro for Mac:

https://raw.github.com/oscardelben/Color-Picker-Pro

This time I built a copy of the iPhone Calculator which (I hope) will be simple to follow for beginners:

I hope this will be useful to people who are learning Cocoa. Feedbacks are very appreciated.

That's a fantastic idea. Just one suggestion, maybe you want to include simple games like Tic-Tac-Toe or Guess the number. When I tried to learn Obj-C I started writing those games first.

Keep us posted.

Thanks for the feedback, I have a snake proof of concept on my github profule which was built with cocos2d, but I'll add more

Thanks a lot for open sourcing Color Picker Pro, I think it's an awesome utility.

As for the calculator, it nice to see a different approach to a simple problem. There is, however, a line of code missing from the :buttonPressed function. For the case of kButtonSubtract, it needs to set deleteInput to YES.

Thanks for the awesome Cocoa contributions. Please, keep it up.

pull request merged, I missed that in a refactoring! Should probably add tests in the next product.
