addPersistentStoreWithType 的 iOS 核心数据 + iCloud 错误 : You don’t have permission to save the file “store” in the folder

Question

我从头开始创建了一个核心数据项目，我所做的唯一改变是在持久协调器添加存储的地方，我提供了一个 NSPersistentStoreUbiquitousContentNameKey 选项:

coordinator.addPersistentStoreWithType(NSSQLiteStoreType, configuration: nil, URL: url, options: [NSPersistentStoreUbiquitousContentNameKey : "coreDataiCloudTestStore"])

我在启动时插入并保存一个新的托管对象。

启动时没有 iCloud 帐户登录，没有问题。当应用程序运行时，我正在登录 iCloud 并返回到应用程序。我收到此错误:您无权在文件夹中保存文件“store”，不允许操作:

CoreData: error: -addPersistentStoreWithType:SQLite configuration:PF_DEFAULT_CONFIGURATION_NAME URL:file:///var/mobile/Containers/Data/Application/9032B2BC-BE8B-42C9-A9CC-EF3E01AA6F2B/Documents/SingleViewCoreData.sqlite options:{ NSPersistentStoreUbiquitousContentNameKey = coreDataiCloudTestStore; PFUbiquitySetupSynchronousSideLoadKey = 1; }

... returned error Error Domain=NSCocoaErrorDomain Code=513 "You don’t have permission to save the file “store” in the folder “380E290C-97F9-4DC3-9B3C-43322FCA455D”."

为什么会这样？

Answer 1

• 这可能是由于您在添加持久存储时传入的选项所致，
• 当您不让核心数据处理重建支持 icloud 的持久存储时，就会发生这种情况，

• 您必须在选项中启用 NSPersistentStoreRebuildFromUbiquitousContentOption 标志

  看苹果文档 https://developer.apple.com/library/ios/documentation/DataManagement/Conceptual/UsingCoreDataWithiCloudPG/UsingSQLiteStoragewithiCloud/UsingSQLiteStoragewithiCloud.html

从 iCloud 重建

To remove local data and start fresh with the existing records in iCloud, pass the NSPersistentStoreRebuildFromUbiquitousContentOption option with a value of @YES when you add your iCloud-enabled persistent store to the persistent store coordinator. Include any iCloud options you usually include.
