FQL查询iOS中的事件不工作

Question

所以，这里是我的FQL查询检索地点为用户事件：

NSString* fql1 = [NSString stringWithFormat: 
         @"SELECT venue from event WHERE eid in (SELECT eid FROM event_member WHERE uid = me())"]; 
    NSString* fql2 = [NSString stringWithFormat: 
         @"SELECT name FROM page WHERE page_id IN (SELECT venue.id FROM #event_info)"]; 
    NSString* fqlStr = [NSString stringWithFormat: 
        @"{\"event_info\":\"%@\",\"event_venue\":\"%@\"}",fql1,fql2]; 
    NSDictionary* params = [NSDictionary dictionaryWithObject:fqlStr forKey:@"queries"]; 

    FBRequest *fql = [FBRequest requestWithGraphPath:@"fql.query" parameters:params HTTPMethod:@"POST"]; 

    [fql startWithCompletionHandler:^(FBRequestConnection *connection, 
             id result, 
             NSError *error) { 
     if (result) { 
      NSLog(@"result:%@", result); 
     } 
     if (error) { 
      NSLog(@"error:%@", error); 
     } 
    }]; 

查询本身是好的，我试图在图形API浏览器。但我得到这个错误：

error:Error Domain=com.facebook.sdk Code=5 "The operation couldn’t be completed. (com.facebook.sdk error 5.)" UserInfo=0x1f01da20 {com.facebook.sdk:HTTPStatusCode=403, com.facebook.sdk:ParsedJSONResponseKey={ 
    body =  { 
     error =   { 
      code = 240; 
      message = "(#240) Requires a valid user to be specified (either via the session or via the API parameter for specifying the user."; 
      type = OAuthException; 
     }; 
    }; 
    code = 403; 
}, com.facebook.sdk:ErrorSessionKey=<PFReceptionist: 0xb2426b0>} 

我做错了什么？这不是我对会话的第一个查询，我要求提供user_events权限和事件工作正常的简单非FQL查询。

下面是它的样子。纠正我错误的情况下。

NSString *query = 
@"{" 
@"'event_info':'SELECT eid, venue, name, start_time, end_time, creator, host, attending_count from event WHERE eid in (SELECT eid FROM event_member WHERE uid = me())'," 
@"'event_venue':'SELECT name, location, page_id FROM page WHERE page_id IN (SELECT venue.id FROM #event_info)'," 
@"}"; 
NSDictionary *queryParam = [NSDictionary dictionaryWithObjectsAndKeys: 
          query, @"q", nil]; 

[FBRequestConnection startWithGraphPath:@"/fql" parameters:queryParam 
        HTTPMethod:@"GET" completionHandler:^(FBRequestConnection *connection, 
        id result, NSError *error) { 
    if (error) { 
     NSLog(@"Error: %@", [error localizedDescription]); 
    } else { 

     NSArray* data = [result objectForKey:@"data"]; 
     NSArray* events = [((NSDictionary*) data[0]) objectForKey:@"fql_result_set"]; 
     NSArray* venues = [((NSDictionary*) data[1]) objectForKey:@"fql_result_set"]; 

     NSLog(@"Result: %@", result); 
    }   
}
