針對addPersistentStoreWithType的iOS Core Data + iCloud錯誤：您無權將文件「store」保存在文件夾中

Question

我從零開始創建了一個Core Data項目，我所做的唯一更改是，持久協調器是增加一個店，我提供了一個NSPersistentStoreUbiquitousContentNameKey選項：

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

，我將和保存推出一個新的管理對象。

在啓動時沒有iCloud帳戶登錄，沒有問題。在應用程序運行時，我正在登錄到iCloud並回到應用程序。我得到這個錯誤：您沒有權限來保存文件「存儲」文件夾中，操作不允許：

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」."

這究竟是爲什麼？

Answer 1

• 這大概是由於你添加持久性存儲時傳遞的選項，
• 它發生時，你不要讓核心數據處理重建啓用iCloud中的持久存儲，

• 你必須啓用NSPersistentStoreRebuildFromUbiquitousContentOption標誌的選項

  看看蘋果文檔 https://developer.apple.com/library/ios/documentation/DataManagement/Conceptual/UsingCoreDataWithiCloudPG/UsingSQLiteStoragewithiCloud/UsingSQLiteStoragewithiCloud.html

從iCloud中

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.
