当管理对象模型更新时，其关系模型不会更新

[英]When a managed object model updates its relationship model is not getting updated

原文 2019-05-23 11:41:04 6 1 ios/ swift/ core-data/ nsmanagedobject

I have a feed model which is having one-many relationship with user model. 我有一个供稿模型，它与用户模型有很多关系。 When I am updating a parameter on user model on mainQueueContext, my feed model is pointing to that old user model. 当我在mainQueueContext上的用户模型上更新参数时，我的提要模型指向该旧用户模型。

Can someone help me where could be the problem? 有人可以帮我解决问题吗？

The issue issue is with both are in different context. 问题在于两者都处于不同的环境中。 When we use parent and child context we should make sure to save parent context also. 使用父级和子级上下文时，还应确保也保存父级上下文。
