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:

Otherwise, the delegate class should implement the NSURLConnectionDataDelegate protocol.
