问题描述

我的 iOS 应用的 Firestore 缓存似乎与 Firestore 不同步.结果我不得不禁用持久性.有没有办法重置缓存?有没有办法确保它始终保持同步?我所做的只是从数据库中删除文档！

My iOS app's firestore cache seems to have got out of sync with Firestore. As a result I've had to disable persistence. Is there anyway to reset the cache? And is there a way to make sure it's constantly in sync? All I did was delete documents from the database!

推荐答案

API 中现在有一个用于清除持久性的功能.除了测试，不推荐用于任何其他用途，但您可以使用

There is now a feature in the API for clearing persistence. It is not recommended for anything but tests, but you can use

firebase.firestore().clearPersistence().catch(error => {
  console.error('Could not enable persistence:', error.code);
})

它必须在使用 Firestore 数据库之前运行.

It must run before the Firestore database is used.
