facebook api requestWithGraph doesnt work

i am work开发者_如何学Going with facebook API and next line is causing me problems:

[facebook requestWithGraphPath:(@"%@/friends",[tmpFriendID objectAtIndex:i]) andDelegate:self];

i need to access friends of certain contact so im passing in -ID of contact-/friends, but somehow it sends in just the ID and so in resoult im not getting friends, but contact profiles.

what am i doing wrong?

remove close paranthesis

change this

 [facebook requestWithGraphPath:@"%@/friends",[tmpFriendID objectAtIndex:i]) andDelegate:self];

to

 [facebook requestWithGraphPath:[NSString stringWithFormat:@"%@/friends",[tmpFriendID objectAtIndex:i]] andDelegate:self];

OR

 [facebook requestWithGraphPath:[NSString stringWithFormat:@"%i/friends",[tmpFriendID objectAtIndex:i]] andDelegate:self];

Moreover see my answer for get friendlist

Retrieve Facebook friends list
