Interface NSURLConnectionDelegate

All Known Subinterfaces:

NSURLConnectionDataDelegate, NSURLConnectionDownloadDelegate

public interface NSURLConnectionDelegate

[@protocol] NSURLConnectionDelegate Delegate methods that are common to all forms of NSURLConnection. These are all optional. This protocol should be considered a base class for the NSURLConnectionDataDelegate and NSURLConnectionDownloadDelegate protocols. connection:didFailWithError: will be called at most once, if an error occurs during a resource load. No other callbacks will be made after.

connectionShouldUseCredentialStorage: will be called at most once, before a resource load begins (which means it may be called during construction of the connection.) The delegate should return TRUE if the connection should consult the shared NSURLCredentialStorage in response to authentication challenges. Regardless of the result, the authentication challenge methods may still be called. connection:willSendRequestForAuthenticationChallenge: is the preferred (Mac OS X 10.7 and iOS 5.0 or later) mechanism for responding to authentication challenges. See for more information on dealing with the various types of authentication challenges. connection:canAuthenticateAgainstProtectionSpace: connection:didReciveAuthenticationChallenge: connection:didCancelAuthenticationChallenge: are deprected and new code should adopt connection:willSendRequestForAuthenticationChallenge. The older delegates will still be called for compatability, but incur more latency in dealing with the authentication challenge.
