Facebook FQL multiquery in iOS SDK - iphone

Question

I am looking for some documentation or sample code on how to send multiquery fql requests to Facebook via iOS SDK.
I found some older samples but they doesnt work for me.
I have populated an NSDictionary with the queries and I try to send the request via
[[FBRequest requestWithDelegate:self] call:#"facebook.fql.multiquery" params:params];, as stated in the samples I have read, but I get an "unrecognized selector sent to class" error and I cant find the "requestWithDelegate" method in FBRequest.h either. Is it deprecated?
Some help on this would be very appreciated!

// Construct your FQL Query
NSString* fql = [NSString stringWithFormat:#"SELECT uid, name, hometown_location from user where uid IN (SELECT uid2 FROM friend WHERE uid1=%lld) and hometown_location != '' ORDER BY rand() limit 4", facebookId];
// Create a params dictionary
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObject:fql forKey:#"query"];
// Make the request
[facebook requestWithMethodName:#"fql.query" andParams:params andHttpMethod:#"GET" andDelegate:self];
The the delegate FBRequestDelegate will be call with the response. Depending on your needs, you'll do something like:
- (void)request:(FBRequest*)request didLoad:(id)result {
NSLog(#"didLoad() received result: %#", result);
}
The facebook object is created like:
Facebook * facebook = [[Facebook alloc] initWithAppId:kAppID];
More info on how to set this up can be found here:
https://developers.facebook.com/docs/guides/mobile/
And depending on your FQL query, you will need permissions from the user. See the list of permissions here:
https://developers.facebook.com/docs/authentication/permissions/
There is also a test console for FQL queries here:
https://developers.facebook.com/docs/reference/rest/fql.query/
And if you want to do an Multiquery instead of a single query, it would look like:
NSString* fql1 = [NSString stringWithFormat:
#"select uid2 from friend where uid1 == %lld order by rand() limit 10", facebookId];
NSString* fql2 = [NSString stringWithFormat:
#"select uid, name from user where uid in (select uid2 from #queryID)"];
NSString* fql3 = [NSString stringWithFormat:
#"select uid, status_id, message from status where uid in (select uid from #queryName) limit 1"];
NSString* fql = [NSString stringWithFormat:
#"{\"queryID\":\"%#\",\"queryName\":\"%#\",\"queryStatus\":\"%#\"}",fql1,fql2,fql3];
NSDictionary* params = [NSDictionary dictionaryWithObject:fql forKey:#"queries"];
[facebook call:#"fql.multiquery" params:params];
