iOS上的Firebase参考 [英] Firebase reference on iOS

问题描述

我是iOS上使用Firebase的新手.我有多个需要访问Firebase ref对象的视图控制器.我可以为每个视图控制器创建一个新的引用实例吗?Firebase是否在内部仅保留1个参考?

I am new to using Firebase on iOS. I have multiple view controllers that need access to the Firebase ref object. Is it okay for me to create a new ref instance for every view controllers? Does Firebase internally keep only 1 ref?

对我来说，另一种选择是创建一个具有Firebase实例作为成员的单例类，然后在每个VC中重用.

Another alternative is for me to create a singleton class with a Firebase instance as a member, then reuse in every VC.

推荐答案

Firebase引用是轻量级的对象.Firebase SDK保持与服务器的单一连接，所有引用都可以重复使用.因此，您可以保留许多参考，而不会引起网络问题.

Firebase references are lightweight objects. The Firebase SDK keeps a single connection to the server that all references re-use. So you can keep many references without introducing network problems.
