title: Facebook FQL multiquery in iOS SDK
body: <p>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 <code>NSDictionary</code> with the queries and I try to send the request via
  <code>[[FBRequest requestWithDelegate:self] call:@"facebook.fql.multiquery" params:params];</code>, 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!</p>
