Question

I want make some progress bar in my application with three20 library when sending data to server. Can someone help me with this?

I am using

- (void)requestDidStartLoad:(TTURLRequest*)request

and

- (void)requestDidFinishLoad:(TTURLRequest*)request

I have found solution.
You must call
[request send];
to call this delegate function:

- (void)requestDidUploadData:(TTURLRequest *)request
{
    float progress = request.totalBytesLoaded / (float)request.totalBytesExpected;

    HUD.progress = progress;
    HUD.labelText = [NSString stringWithFormat:@"Progress %d%%", (int)(progress*100)];
}

if you call sendSynchronously data will send but you can’t get totalBytesLoaded.
