You just have to send your friend's Facebook ID as a parameter under the key "target_id".

OLD SDK: set the FBStream dialog's targetId property.

NEW SDK: set a parameter under the key @"target_id" on the parameters dictionary (when invoking dialog:andParams:andDelegate: on the Facebook object).

Here you have a sample post using the new sdk (the one that uses graph api):

NSMutableDictionary* params = [NSMutableDictionary dictionary];
[params setObject:@"Some text" forKey:@"user_message_prompt"];
[params setObject:@"another text" forKey:@"action_links"];
[params setObject:@"Yet another text" forKey:@"attachment"];
[params setObject:@"SOME FACEBOOK ID" forKey:@"target_id"];

//At some point you need to create the following Facebook instance

[facebook dialog: @"stream.publish"
    andParams: params
    andDelegate: self];

I haven't actually tested this code, but this is a pretty straight-forward thing to once you have already posted a message to your wall.

Hope this helps. Cheers!
