iOS sample canAuthenticateAgainstProtectionSpace always returns NO

[Dmitry-Me]

In iOS sample canAuthenticateAgainstProtectionSpace always return NO because authenticationDelegate is never set and so is nil at all times. The most likely resolution is to just remove canAuthenticateAgainstProtectionSpace - the default behavior should be okay.

iOS sample was updated - now it uses AFNetworking, so this issue should be closed.
