依靠NSUbiquitousKeyValueStore存储基本数据是否安全？ [英] Is it safe to rely on NSUbiquitousKeyValueStore for storing essential data?

问题描述

我了解到 NSUbiquitousKeyValueStore 始终可用，当没有iCloud帐户<时/ a>已设置。这让我相信我可以安全地存储基本数据，而无需在 NSUserDefaults 中保留副本。

I learned that NSUbiquitousKeyValueStore is always available, also when no iCloud account is set up. This makes me believe I can safely store essential data in it, without keeping a copy in NSUserDefaults.

但是， Apple的文档中说明如下：

However, in their documentation, Apple says the following:

避免将此类用于离线时应用程序行为必不可少的数据;相反，将这些数据直接存储到本地用户默认数据库中。

Avoid using this class for data that is essential to your app’s behavior when offline; instead, store such data directly into the local user defaults database.

我是否忽略了不使用<$ c $时可能出现的问题c> NSUserDefaults （或其他离线商店）作为备份？或者Apple是否过度保护，依赖 NSUbiquitousKeyValueStore ？

Do I overlook issues that might arise when not using NSUserDefaults (or another offline store) as back-up? Or is Apple being overprotective and is it safe to rely on NSUbiquitousKeyValueStore?

What this means is that you should not rely on this store to be your local truth but more of a simple sync communication channel between your devices.
