Asynchronous NSURLConnection with NSOperation

Question

I want to do NSURLConnection in background mode,because it response is having much data.Forums are telling to use Apple\'s finite length coding to use in

Answer 1

This kind of question was asked a zillion time. Delegates are not getting called because as of iOS 4 operations are started on a secondary thread. The thread probably exits before the delegates are called that's all.

Keep the connection on the main thread and handle the data in a background thread using GCD.
