You are actually missing a key: ACFacebookAudienceKey. You can change it like that:

NSDictionary *options = [[NSDictionary alloc] initWithObjectsAndKeys:
                                 (NSString *)ACFacebookAppIdKey, @"##########",  
                                 (NSString *)ACFacebookPermissionsKey, [NSArray arrayWithObject:@"email"],
                                 (NSString *)ACFacebookAudienceKey, ACFacebookAudienceEveryone,
                                 nil];

By the way, when you are using Twitter, the options must be nil.
