Answer 1

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.

Answer 2

You have inverted objects and keys in your options dictionary :

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