NSURLSession delegate

I can't seem to get the NSURLSession delegate to fire. What all do i need to do? I have all 4 of the delegate protocols implemented but they never seem to fire. For a UITextField delegate, you would assign the delegate by saying textField.delegate = self; but i'm lost on the NSURLSession. Basically my goal is to have a UIProgressView show the progress of a NSURLSessonDownloadTask, i know what to do but just need help with the delegate. Thanks

Never mind, I was using...

 - (NSURLSessionDownloadTask *)downloadTaskWithRequest:(NSURLRequest *)request completionHandler:(void (^)(NSURL *location, NSURLResponse *response, NSError *error));

and apparently you can't use the completion block or the delegate will not fire, instead this worked for me.

- (NSURLSessionDownloadTask *)downloadTaskWithRequest:(NSURLRequest *)request;

Now the delegate gets fired.
