ios - 仅 IOS 8 中的核心数据迁移问题，而不是 IOS 9

Question

我在 Core Data 迁移时遇到了奇怪的 IOS 应用程序问题。以下是您提到的日志 此问题仅在 IOS8 设备将应用程序从较低版本迁移到较新版本时发生。请注意，我已经在 IOS9 中使用该模型通过了此测试版本光数据迁移升级。

任何快速帮助在生产中都非常感谢。

在 iOS 8 及以下版本中，您需要在项目中显式创建新版本的架构，以便 iOS 可以比较应用程序包中的两个架构并执行轻量级迁移。

在 iOS 9 中，核心数据存储将当前模式与 (sqlite) 数据文件一起存储，这样如果/当您更改应用程序包中的模式时，它可以在捕获的模式之间执行轻量级迁移磁盘和应用程序包中的新模式。
