在多个视图之间保持同步活动的最佳实践或设计模式是什么? [英] What is the best practice or design pattern to maintain sync activity across multiple views?

问题描述

场景:共享/同步领域.具有多个视图的iOS/Swift应用.

Scenario : Shared/Sync'd Realm. iOS/Swift App with multiple views.

为了在后台保持同步，并为多个视图提供自动(实时)更新，我应该使用哪种最佳实践设计模式?

What is the best practice design pattern I should use to in order to maintain synchronisation in the background - and - provide automatic (real time) updates to multiple views?

查看额外的任务应用程序-这很有意义，但是该应用程序实际上只有一个活动视图.如果我有多个视图怎么办?

Looking at the extra task app - this makes sense but the app really only has one active view. What if I have multiple views?

是否应该销毁Realm的数据更改通知并为每个视图重建?

Should I destroy the Realm notification of data change and rebuild for each view?

推荐答案

推荐的方法与单个视图控制器的方法相同.为每个视图控制器获取一个Results对象，并将其直接用作数据源.您可以使用Realm的通知机制来观察Results对象.当更改影响结果时，从后台线程提交任何更改，都会触发通知.结果对象已自动更新为最新状态，您只需要更新用户界面即可.

The recommended way is the same as for a single view controller. Get a Results object for each view controller and use it directly as a data source. You can observe that Results object using Realm's notification mechanism. A notification fires when changes affecting Results any changes are committed from a background thread. The Results object has been updated to the latest state automatically, what you should do is just updating the UI.
