I've implemented an FTPHelper class, that does the FTP communication for me using BlackRaccoon, however, all the delegate/required methods are not called.
I'm trying to download a database file from my FTP server, it's not storing though, it did download it, since the data isn't communicated back requestCompleted.
I'm sure that my FTP server is working, and that the data is being transferred because I placed print statements in BRStreamInfo.m. In my understanding, when the stream is complete it should call requestCompleted according to the following snippet
- (void)streamComplete:(BRRequest *)request
{
NSLog(@"Stream Complete");
[request.delegate requestCompleted: request];
NSLog(@"Data tranferred back to FTP helper requestCompleted");
[request.streamInfo close: request];
}

#import "Utility.h"

//----- for anonymous login just leave the username and password nil
