iPhone facebook connect FQL Query to get user's friends

I'm trying to get a list of user's friends using fb connect for t开发者_如何学运维he iphone.

I've tried both of the following FQL Queries, but they don't seem to be returning anything.

which one is correct if any ?

NSString* fql = [NSString stringWithFormat:@"select flid,name from friendlist where owner=%lld",[self fbSession].uid]; 

or

NSString* fql = [NSString stringWithFormat:@"SELECT flid,uid FROM friendlist_member WHERE flid IN (SELECT flid FROM friendlist WHERE owner=%lld)",[self fbSession].uid];

Ah.. figured it out...

NSString* fql = [NSString stringWithFormat:@"SELECT name,uid FROM user WHERE uid IN ( SELECT uid2 FROM friend WHERE uid1=%lld )",[self fbSession].uid];
