私下协商协议

有没有办法隐藏来自最终用户的协议符合？我将尝试详细描述我想要的。我有类让我们称之为 EndUserClass ，它符合一些协议，让我们说 HiddenClassDelegate 和我想从最终用户隐藏的协议。代码如下所示：

Is there any way to hide protocol conforming from an end user? I'll try to describe in details what I want. I have class let's call it EndUserClass which conforms some protocol let's say HiddenClassDelegate and this protocol I'd like to hide from end user. The code looks like as it follows:

@interface EndUserClass : NSObject  <HiddenClassDelegate>
{
  // .....
}   

@end

并且我想使用以下声明保持相同的功能：

and I want to keep the same functionality with the following declaration:

@interface EndUserClass : NSObject  
{
  // .....
}   

@end

有没有办法私下符合协议？我知道我可以在类声明中跳过委托，但它给出了我不想要的编译器警告

Is there any way to conform the protocol privately? I know that I can skip delegate in class declaration but it gives compiler warning which I don't want to have
