But , i have made a solution to you folks ...

获取动作和控制器

像Weclome / Home，users / login，sell / sell，sell / index，sell /'，'/'

   //get the current URL
    $controller= $this->uri->segment(1); // controller
    $action = $this->uri->segment(2); // action
    $url = $controller . '/' . $action; 
    //'this returns / sometimes and  also  like sell/ returned'


 if(  ($this->ion_auth->logged_in()== false )&& (in_array($url,$public_allowed_urls) ) )
 {                  
  redirect('users/login');
  }

done men！

已编辑：

$ this-> uri-> segment（1）; 不能是控制器名称所有时间。获取控制器名称使用 $ this-> router-> class 和方法 $ this-> router->

$this->uri->segment(1); cannot be controller name all time.To get controller name use $this->router->class and for method $this->router->method
