问题描述

我的CoreData驱动的应用程序有来自同一商店的数据的多个视图。所有使用NSFetchedResultsController。目前，它们都有相同的名称为NSFetchedResultsController缓存，根。我的应用程式的使用者可以大概会，在观点之间不分青红皂白地跳跃。如果我给每个NSFetchedResultsController的缓存一个唯一的名称，对用户体验会更好吗？

My CoreData driven app has a number of views of data from the same store & all using an NSFetchedResultsController. Currently they all have the same name for the NSFetchedResultsController cache, "Root". Users of my app can, & probably will, jump indiscriminately between views. Would it be better for user experience if I gave the cache for each NSFetchedResultsController a unique name?

TIA，Pedro：）

推荐答案

为不同的抓取提供不同的缓存名称是可取的并且有助于提高性能。

Providing a different cache name for different fetches is advisable and will help with performance.

如果你有多个获取的结果
控制器与不同的
配置（不同的排序
描述符等），你必须给
每个都有不同的快取名称。

If you have multiple fetched results controllers with different configurations (different sort descriptors and so on), you must give each a different cache name.
