I am really excited about being apart of a great community Raywenderlich.com!
It is a web site that provides high quality programming tutorials for iOS, Android, Mac and many other technologies. I have written a tutorial about NSScanner for Mac OS X development. The tutorial is about creating automated parsers with NSScanner. It was a great learning experience as I have never done Mac OS X development before, but it is very similar to iOS development. By writing this tutorial I not only help others understand and make use of NSScanner, but also taught myself and it certaintly gave me a better understanding about NSScanner and parsing strings.
I look forward to writing more tutorials on Raywenderlich.com. Keep a look out for some more in the near future!
