核心数据 NSFetchedResultController 未在对象更改时更新？
我有一个带有此谓词集的 NSFetchedResultController：
NSPredicate* pred = [NSPredicate predicateWithFormat:@"author != %@ && deleted != %@", [NSNumber numberWithLongLong:0],[NSNumber numberWithBool:YES]];
它在启动时过滤得很好，如果添加或删除对象，我会得到一个委托回调并列表更新。
但是，如果我更改“已删除”字段，则 NSFetchedResultController 集不会更新，也不会收到回调。
虽然 NSFetchedResultController 中的实际对象已更新，但如果我在表上执行“reloadData”并检查“deleted”的值，它实际上设置为 YES。
为什么它没有从 NSFetchedResultController 中消失？
这是预期的行为吗？ 或者我可能做错了什么？
I have a NSFetchedResultController with this predicate set:
NSPredicate* pred = [NSPredicate predicateWithFormat:@"author != %@ && deleted != %@", [NSNumber numberWithLongLong:0],[NSNumber numberWithBool:YES]];
It filters fine on startup, and I get a delegate callback and list updates fine if objects are added or deleted.
But if I change the "deleted" field, the NSFetchedResultController set is NOT updated, nor do I get the callback.
Though, the actual object in the NSFetchedResultController is updated, if I do a "reloadData" on my table and check the value of "deleted", it is actually set to YES.
Why is it not disappearing from the NSFetchedResultController?
Is this expected behavior?
Or what could I be doing wrong?

我想我解决了它......
事实证明我确实得到了回调（“didChangeObject”），现在我在这里检查“deleted”的值，如果该值为 YES，则手动将其从 NSFetchedResultController 中删除。
似乎有效，但我仍然希望它是自动的。
I guess I solved it...
Turns out I actually do get the callback ("didChangeObject") and I now check the value of "deleted" here and manually remove it from the NSFetchedResultController if the value is YES.
Seems to work, but I still did expect it to be automatic.
