objective-c - 即使请求明确表示没有错误，也执行 Fetch Result 返回错误

Question

永久存储顺便说一句是内存，我想知道它是否合理

这是3行代码：

PO(request);
fetchedObjects = [moc executeFetchRequest:request error:&error];
PO(fetchedObjects);

请求对象：

request: <NSFetchRequest: 0x8eba110> (entity: Business; predicate: (ID IN {"monumen-selamat-datang__-6.19_106.82"}); sortDescriptors: ((null)); type: NSManagedObjectResultType; returnsObjectsAsFaults: NO; relationshipKeyPathsForPrefetching: ((
        Aliases,
        Building,
        City,
        DistanceGrouping,
        Districts,
        Images,
        LatitudeLongitude,
        OpeningHour,
        Phones,
        Promotions,
        Rating,
        RatingGroup,
        Reviews,
        Tags,
        Tenants,
        URLs
    )); )

很明显，你可以看到它有returnsObjectsAsFaults: NO

返回值：

fetchedObjects: (
        "<Business: 0x8ebf3e0> (entity: Business; id: 0x8c4af70 <x-coredata://0111F3D9-6254-4037-AC80-5FEBECEB2343/Business/p332> ; data: <fault>)"
    )

它包含：data: <fault>
