ios - iOS，为什么 iCloud 在第二台设备上同步对象但不同步对象的属性

Question

iOS iCloud 确实在第二台设备上同步对象，但不同步对象的属性

• NonSyncing 属性：类别

• 应用程序：通用 iOS，CoreData 库样式，使用 FRC 处理 tableViews，没有 GarbageCollection

• 设备：5.1.1 上的 iPhone 4、iPad 1 都运行相同的 iOS 应用程序。

• XCode 4.3.2

• 数据模型：

** 实体关系目标反向 **

   Recipe       categories      Category        recipes

   Category     recipes         Recipe          categories

• 相关对象：Recipe 和Category，第一个有可选的to-many 属性类别，第二个有成对的可选to-many 属性recipe。Recipe 的其他属性包括成分、NSString*

• 程序：在 iPad 应用程序上，在 MOC 中创建一个新配方，然后我将现有类别添加到配方 obj 中，然后添加一些成分文本。然后我保存：到MOC，--唯一保存：调用。新食谱在 iPhone 上与配料文本同步，但缺少在 iPad 上添加和保存的类别。此搜索类别在添加它的 iPad 上“有效”，但在 iPhone 上无效，也就是说，该类别未添加到第二台设备的新配方的类别属性中。iCloud 将两个 *.cdt 文件放在 iPhone 上。

下面是Recipe和Category的Class接口和实现文件，以及iPhone上出现的两个Log文件的内容plist

• 问题：我希望这些信息足以让您告诉我在哪里寻找修复？我不确定在这里提供什么信息。iCloud 不应该自己处理这个属性同步吗？

谢谢您阅读此篇！标记
