How to resume the downloading file in ios sdk
<p>I am developing one universal application. In that i did the downloading functionality using <code>NSURLConnection</code> class. But here my problem is i want to provide the resume functionality for that one. I am downloading the files from my server. After download complete, I am unzipping that zip file and stored to folder. So how can i provide resume functionality and how can I remember how much file is downloaded?</p>
