使用FQL我能得到查詢響應與參數is_app_use

NSMutableDictionary * params = [NSMutableDictionary dictionaryWithObjectsAndKeys: 
           @"select uid, name,pic_small, is_app_user from user where uid in (select uid2 from friend where uid1=me()) and is_app_user=1", @"query", 
           nil]; 
[[APPDELEGATE facebook ] requestWithMethodName: @"fql.query" 
             andParams: params 
            andHttpMethod: @"POST" 
            andDelegate: self];
