The NSURLConnectionDelegate protocol defines methods common to the NSURLConnectionDataDelegate and NSURLConnectionDownloadDelegate protocols.

The NSURLConnectionDelegate protocol defines methods common to the NSURLConnectionDataDelegate and NSURLConnectionDownloadDelegate protocols.

Delegates of NSURLConnection objects should implement either the data or download delegate protocol (including the methods described in this protocol). Specifically:

If you are using NSURLConnection in conjunction with Newsstand Kit’s downloadWithDelegate: method, the delegate class should implement the NSURLConnectionDownloadDelegate protocol.

Otherwise, the delegate class should implement the NSURLConnectionDataDelegate protocol.
