How to revoke access_premission in Facebook graph api to give user ability to relogin.

With the latest Facebook SDK it's quite easy:

FBRequest *request = [FBRequest requestForDeleteObject:@"me/permissions"];
[request startWithCompletionHandler: ^(FBRequestConnection *connection, NSDictionary* result, NSError *error) {}
