Regarding “didFailWithError” and “connectionDidFinishLoading“
Can they both be called? Or its always one or the other?
No, they cannot be called at the same time.
After the delegate receives a message
connection:didFailWithError:, it receives no further delegate messages for the specified connection.If the connection succeeds in downloading the request, the delegate receives the
connectionDidFinishLoading:message. The delegate will receive no further messages for the connection and theNSURLConnectionobject can be released.http://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/URLLoadingSystem/Tasks/UsingNSURLConnection.html
