iOS needs a block-based UIAlertView. So many currently-delegate based interfaces would be better served by block callbacks.
JCDHTTPConnection is a pretty simple class that takes a NSURLRequest object and (up to) three block callbacks: onSuccess, onFailure, and onDidSendData. It’s asyncronous, of course, and much more convenient than setting up a delegate. I’m pretty happy with it, and I hope it might help someone out.
