Question

I am using iOS sdk5.0. I am hitting a link using NSURLConnection and creating a request. But my control is not going into didReceiveAuthenticationChallenge method. Is didReceiveAuthenticationChallenge not called in iOS5.0?

Answer 1

According to Docs of NSURLConnectionDelegate

connection:canAuthenticateAgainstProtectionSpace:
connection:didReciveAuthenticationChallenge:
connection:didCancelAuthenticationChallenge:

are deprecated and new code should adopt

connection:willSendRequestForAuthenticationChallenge

The older delegates will still be called for compatibility, but incur more latency in dealing with the authentication challenge.
