You can get expected total file size in following callback method of NSURLconnection,

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
   expectedTotalSize = response.expectedContentLength;
}

then in the following callback method you can calculate how much data has been recieved,

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
   recievedData += data.length;
}

And you can use UIProgressView to show current downloading status on the screen.

    Just a guess, but he tagged his question with afnetworking-2 so I'm assuming he wants to use that library. – Lance Sep 27 '13 at 19:17
