title: How to know which request a FB Graph's response respond to?
body: <p>I make a call to FB graph api using FB IOS and handle the response in a delegate object which conforms to FBRequestDelegate. The handle functions is</p>
  
  <pre><code>- (void)request:(FBRequest *)request didLoad:(id)result;
  </code></pre>
  
  <p>My question is that how do I know which request this response respond to if two requests with same graph path are made?</p>
  
  <p>Look into FBRequest </p>
  
  <pre><code>@interface FBRequest : NSObject {
      id&lt;FBRequestDelegate&gt; _delegate;
      NSString*             _url;
      NSString*             _httpMethod;
      NSMutableDictionary*  _params;
      NSURLConnection*      _connection;
      NSMutableData*        _responseText;
      FBRequestState        _state;
      NSError*              _error;
      BOOL                  _sessionDidExpire;
  }
  </code></pre>
  
  <p>is there any of these instance variable can be used to distinguish between requests with same graph path?</p>
  
  <p>Thanks </p>
