如何知道Realm查询（RLMResults）操作何时完成？

I am using Realm to handle persisting data to disk in my app.

我正在使用Realm在我的应用程序中处理持久化数据到磁盘。

To return my objects saved in Realm, I use RLMResults which successfully returns objects saved in my database

要返回我在Realm中保存的对象，我使用RLMResults成功返回保存在我的数据库中的对象

RLMResults <Cat *> *cats = [Cat allObjectsInRealm:myRealm];

The problem is I have no way of knowing when this operation is completed. I need my network request to wait on the completion of this query before proceeding. The realm documentation is not very thorough and I can't see a way for me to know when this read operation is complete.

问题是我无法知道此操作何时完成。在继续之前，我需要我的网络请求等待完成此查询。领域文档不是很彻底，我无法看到一种方法让我知道这个读操作何时完成。

Is there some sort of completion block available?

是否有某种完井模块可供使用？

Realm's query APIs are synchronous, and the results they return are available to calling code immediately.

Realm的查询API是同步的，它们返回的结果可用于立即调用代码。
