核心数据 + iCloud：从同步中排除某些属性？

Question

I am trying to implement core data sync using iCloud. However, there is one attribute that I don't want to sync. Is there a proper way to tell iCloud to sync most managed objects and attributes, but not others?

Answer 1

Right now, Core Data + iCloud does not support this kind of configuration. You may have to split your Data into two Persistent Stores (lokal, cloud).

Answer 2

One workaround would be to add the things you do not wish to sync to an entity that includes a unique device identifier.

In this way, they still get synced, but you can use just the data pertinent to the specific device and ignore the data from other devices.
