How to pause and resume downloading in iphone app?

Question

By using default NSURLConnection and its delegate methods we can easily download the files. while downloading if internet connection is not available the downloading process has to be paused & after connection established resume the downloading..

Can any one explain me how can I implement this, and If you have any sample code relating to the pause, resume downloading. If it is in Objective-c, or C is better.

Answer 1

Take a look to ASIHTTPRequest

As of v0.94, ASIHTTPRequest can resume partial downloads.

Edit:
