Small, simple examples of asynchronous transmission in iPhone

Question

I am trying to work on application in which images should be loaded asynchronously.

Are there any examples related this?

I tried pokeb-asi to understand asynchronous transmission, and it works within that application fine.

But I want to know how to do it from scratch

I am facing following problems.

• I don't know the exact way to do it?

• what kind of files / frameworks should be added?

Plz. Go through following link.

Answer 2

The ASIHTTPRequest class is a subclass of NSOperation, so it's typically used by adding the request to either an NSOperationQueue or an ASINetworkQueue. Each request is pulled off the queue, run in a background thread, and then the delegate for that request is notified via a callback method on the main thread.

You could wrap NSURLConnection in an NSOperation and achieve the same thing, however NSURLConnection has an asynchronous API which may suit your needs a bit better.
