  • get time for bytes uploaded in seconds.
  • estimate total time in seconds. This can be found by comparing the bytes
  • find remaining time by finding the difference.
  • use the below to get as hour ,min,sec.

`

- (NSDictionary*)createTimemapForSeconds:(int)seco                                   
  {
       int hours = floor(seco / (60 * 60) );

       float minute_divisor = seco % (60 * 60);
       int minut = floor(minute_divisor / 60);

       float seconds_divisor = seco % 60;
       seco = ceil(seconds_divisor);

       NSDictionary * timeMap = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:[NSNumber numberWithInt:hours], [NSNumber numberWithInt:minut], [NSNumber numberWithInt:seco], nil] forKeys:[NSArray arrayWithObjects:@"h", @"m", @"s", nil]];

       return timeMap;
    }

Using Reachability you can achieve this click here

Using reachability u can calculate the speed of network and then with that speed you can divide remaining bytes and can produce the result of how time remaining for upload,etc..

Hope this helps..

You can save the start date, and on every call of your progress function (or block), compute the elapsed time since start, and find the estimated remaining time amount with a simple cross multiplication, as you know how many bytes there's left :

elapsed_time * total_bytes = total_time * downloaded_bytes
remaining_time = total_time - elapsed_time

But yes, network condition might change anytime, so that's not really accurate.
