I have taken up studying Objective-C for iPhone development. More as a hobby then a business need at this point. For studying I’ve been using the iPhone Developers cookbook. Very easy to follow and well worth reading!
As part of the learning process I normally do up small samples and create write ups of my steps (meta-cognition trick). So I will have a few mini-tutorial/walk through posted as I go. If your already a experienced Objective-C developer you are probably going to find it very noobish. Likewise for Domino developers (for the Domino part). But it is how I learn, and it might help someone else.
Tutorial 1: Connecting to a Domino view.
This creates a very simple Domino application containing 10 records. Then in your iPhone application you connect to the view reading the JSON and using the NSString class to pull just the related information out and display on the apps table. I could of gone with JSON library (not core foundation though) or XML but I wanted to keep it as simple as possible.
Next tutorial will deal with selecting one of those items and reading the documents data. Then continue to build on that.
