Having done the Apple developer tutorial Getting Started on iOS development, the next was to have a deeper dive in Objective-C. Looking around for online Objective-C tutorials, I came across a very good one, on Code School. The tutorial is called Try Objective-C.

I have been technical reviewer on this book. That was a very exciting experience. Click below to see details of the book.
This is my first encounter with iOS apps and Objective C. I followed the whole tutorial which is given here. I am a Ruby developer and I decided to take this trip to iOS development because it is necessary for my work. I am offering professional services to Book&Table, which is sponsoring me writing this blog post.
Following this tutorial, I had to keep some notes. Here are the most important ones. Maybe you will find them useful too. But most importantly, I am seeking feedback from experienced iOS developers.
When you have a Ruby on Rails end point, the client usually sends data in one of the following:
GETrequests, URL encoded in the URI
POSTrequests, in the body of the request encoded with

Many software engineers do not write tests for their UI because they have a good reason not to. Firstly, they believe that UI changes frequently, so any test would have been vulnerable to frequent changes. Secondly, they do not know about the Page Object Pattern.
I just wanted to have the United States, their Counties, the Cities in the Counties and the Zip codes in each City in CSV format. But I wanted that normalized. In different CSVs. So, here it is. You can also find here some Ruby on Rails sample code that loads these files. Primitive stuff, but sometimes useful.
Ruby on Rails migrations are used to create the necessary tables inside our database. One of the most frequently used column type is
Here is an example of an
ActiveRecord::Migration that uses this type:
I have recently finished the book “The Clean Coder – A Code of Conduct for Professional Programmers – R. Martin (Pearson, 2011) BBS”. Here is my short review:
Overall: Fantastic. Worth reading for every developer that wants to become professional.
My Notes and Highlights
Chapter 1 – Professionalism
- Professionalism is a marker of responsibility and accountability.
- It is better to make your manager unhappy rather than your manager customers.
