How can I find tutorials for building an application that gets updates from an online website?

Question

I want to build an application that gets updates from online websites like Twitter or Facebook. Currently, I haven't even got a clue on how to do this.

Also, in certain applications, like Doodle Jump, I have seen updates that pop up. Some other applications have a news section that gets updated often. How is it done? Any tutorial or working code will be very helpful.

Answer 1

There is a good tutorial I used to do this with ASP.NET.

Answer 2

I'm going to guess that you are interested in building an iPhone app. I don't know if you have any experience working with objective-c or the iPhone SDK, but here is a nice tutorial that touches on some of the concepts you will need.
