Custom Graph API request on iPhone SDK - ios4

Question

Is it possible to make a custom Graph API call using FBConnect?
For example,
[facebook requestWithGraphPath:#"me" andDelegate:self];
With this call, I can see my own details.
[facebook requestWithGraphPath:#"me/friends" andDelegate:self];
With this I can see my friends.
[facebook requestWithGraphPath:#"FRIEND_ID/picture" andDelegate:self];
With this I can see a picture from a friend with id=FRIEND_ID.
Is there a possibility to make a custom Graph API call, to take id, picture, name and for example email, of all my facebook friends, in just one call?
Problem that I have is, when I call:
[facebook requestWithGraphPath:#"me/friends" andDelegate:self];
In:
- (void)request:(FBRequest *)request didLoad:(id)result;
I take the IDs of my friends, and then, in a for loop I want to do this:
[[self appDelegate].facebook requestWithGraphPath:[NSString stringWithFormat:#"%#/picture",[[party.attendantsDictionary allKeys] objectAtIndex:i]] andDelegate:self];
Afterwards, in
- (void)request:(FBRequest *)request didLoad:(id)result;
I have:
if ([result isKindOfClass:[NSData class]]) {
[party.attendantsPictures addObject:[[UIImage alloc] initWithData:result]];
}
Problem is that pictures and names of my friends are all mixed up.
Anyone has a solution?

You could try NSRunLoop.
In my case, I wanna load user's name, status, profile picture at once. However, requestWithGraphPath and its delegate didload: result definitely only can handle each request at a time. So what I did is:
1/ Setup a tag number
2/ After each request, wait for the request to be completed, increase tag number by 1
So in my button action,
tagNo = 0;
[facebook requestWithGraphPath:graphPathZero // For user's name
andDelegate:detailVC];
while ( tagNo == 0) && [theRL runMode:NSDefaultRunLoopMode beforeDate:[NSDate distantFuture]]);
[facebook requestWithGraphPath:graphPathOne // For user's status
andDelegate:detailVC];
while ( tagNo == 1) && [theRL runMode:NSDefaultRunLoopMode beforeDate:[NSDate distantFuture]]);
[facebook requestWithGraphPath:graphPathTwo // For user's profile picture
andDelegate:detailVC];
while ( tagNo == 2) && [theRL runMode:NSDefaultRunLoopMode beforeDate:[NSDate distantFuture]]);
And in the delegate,
switch (tagNo) {
case 0:
// Do something with result
break;
case 1:
// Do something with result
break;
case 2:
// Do something with result
break;
default:
break;
}
++tagNo;
I may not cover "Do something with result" here since it's in somewhere else in stackoverflow. This might not be the solution, but I found it approachable. Look for more contributions from others ;)

Hmmm, I've never used NSRunLoop. Could you give me a hint what it is? (Apple's Docs are little confusing...).
In your case, I would do something like this:
NSString *fql = #"SELECT name, uid, pic_square, status FROM user WHERE uid = me() OR uid IN (SELECT uid2 FROM friend WHERE uid1 = me())";
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:fql, #"query", nil];
[facebook requestWithMethodName:#"fql.query" andParams:params andHttpMethod:#"POST" andDelegate:self];
This way, you would get everything from the users, that you want.
