NSURLCredential is permanent?

Question

We have a problem with our iPhone-simulator that was caused by using this line:

    Foo = [NSURLCredential CredentialWithUser:foo 
    password:bar persistance:NSURLCredentialPersistencePermanent];

The problem was created when the credential was given to the challenge over at

        -(NSURLConnection *)connection
        didReceiveAuthenticationChallenge(NSURLAuthenticationChallenge *)challenge
    {

        [[challenge sender]useCredential:Foo forAuthenticationChallenge:challenge]      
    }

So now when we run the application, we dont ever ever again run into the authenticationchallenge again, which is quite odd, even if we change the credential to

    Foo = [NSURLCredential CredentialWithUser:foo 
    password:bar persistance:NSURLCredentialPersistenceForSession];

or even

    Foo = [NSURLCredential CredentialWithUser:foo
    password:bar persistance:NSURLCredentialPersistenceNone];

To summarize:

By using credentialpersistencepermanent the credential is somehow saved somewhere and used automagically to access wherever we need to autenticate ourselves.

So for testing-purposes, we would really like to remove this persistent... credential.

Any ideas anyone? :)

If someone answers this question by stating that i should only have to reset the iPhone-simulator i'll mark that answer as correct. It actually solved the problem, we just didnt ever think about it. — Jens Bergvall, Jun 03 '11 at 11:48

Have you tried just resetting the simulator? It's in the Simulator menu.

It's saved in the keychain. To go from NSURLCredentialPersistencePermanent to a less permanent state like NSURLCredentialPersistenceForSession, you have to remove it and recreate it.

Note that in some versions of the tools resetting the simulator does NOT clear the keychain.
