I am a developer and I know how hard it is to solve difficult issues while programming in case you did not get any help. I have faced this so many times. That's why I started this blog so that I can share problems and solutions with developer community. In case if you face any issue in programming do check my blog once, it will surely save your time.
Please note that here we are using GCD (grand central dispatch) I will explain this in other blog post. We will get our JSON data in receivedData variable. iOS 5 gives native classes for JSON serialization. Following code will go in else loop.
