Using old style access token with SSO FBDialog?

I've an application, that has old style facebook access_tokens (something like "APPID|xyeahsfa-123465683821.---..." ) and an iOS App using the current facebook SDK (with SSO). Using

 Facebook *facebook = [[Facebook alloc] initWithAppId:appId];
 facebook.accessToken = accessToken;
 facebook.expirationDate = [NSDate distantFuture];
 [facebook dialog:@"feed开发者_开发技巧" 
       andDelegate:self]; 

i'm trying to show the User a dialog to post something to facebook. However, this fails with an "An eroor occured with application XY" error. The Error URL I saw said something about "no session cookie to validate against" with errno 110.

With a "new" access token, one that I got from the Single Sign On DemoApp, works just fine.

Has anybody expierenced this or any clue how to work around it?

From your source it looks like you are missing the auth step:

Facebook* facebook = [[Facebook alloc] initWithAppId:appId];
[facebook authorize:permissions delegate:self];
