Answer 1

I'm quite sure this is not possible, you'ld need data access privs of the friends to get their friends data. this has to do with the access rights on fb and this is good for some reasons it is like it is. even if this data protection mechanism disturbs your business idea ;)

Answer 2

If you want catch friend informations you must :

• Alloc and Init a Facebook object

Facebook *facebookObject = [[Facebook alloc] init];

• Check permissions

NSArray *permissions = [NSArray arrayWithObjects:@"publish_stream", @"offline_access",nil];

• Authorize facebook

[facebookObject authorize:APP_ID permissions:permissions delegate:self];

• After that you can used

[facebookObject requestWithGraphPath:@"me/friend" andDelegate:self];

• In delegate methods

- (void)request:(FBRequest *)request didLoad:(id)result

You catch the result who must be a NSDictionnary.
