iCloud核心数据IOS8路径不在任何CloudDocs容器中

Question

我的iCloud核心数据应用程序在iOS7上运行良好并准备启动.当我在iOS 8上测试时,我收到以下错误,并且在尝试将数据上传到iCloud时似乎无法修复它.

我怀疑我的问题与我如何获取文档目录以及iOS8中的doc目录中的更改有关,但我无法弄清楚这一点.

我创建持久存储的应用程序委托扩展代码如下所示.我有第一次安装的种子数据库.

- (NSPersistentStoreCoordinator *)createPersistentStoreCoordinator{
   NSPersistentStoreCoordinator *persistentStoreCoordinator = nil;
   NSManagedObjectModel *managedObjectModel = [self createManagedObjectModel];
   persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc]initWithManagedObjectModel:managedObjectModel];
   NSURL *storeURL = [[self applicationDocumentsDirectory] URLByAppendingPathComponent:@
   "CoreData.sqlite"];    

   if (![[NSFileManager defaultManager]fileExistsAtPath:[storeURL path]]){
       NSURL *preloadURL=[NSURL fileURLWithPath:[[NSBundle mainBundle]pathForResource:@"SeedDatabase" ofType:@
       "sqlite"]];
       NSError *error=nil;
       if (![[NSFileManager defaultManager] copyItemAtURL:preloadURL toURL:storeURL error:&error]){
           NSLog(@
           "File couldnt save");
       }
   }


   NSUbiquitousKeyValueStore *kvStore=[NSUbiquitousKeyValueStore defaultStore];
   if (![kvStore boolForKey:@"SEEDED_DATA"]){
       NSLog (@
       "In the new database");
       NSURL *seedStoreURL=[NSURL fileURLWithPath:[[NSBundle mainBundle]pathForResource:@"SeedDatabase" ofType:@
       "sqlite"]];
       NSError *seedStoreErrpr;
       NSDictionary *seedStoreOptions=@{NSReadOnlyPersistentStoreOption: @YES};
       NSPersistentStore *seedStore=[persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:seedStoreURL options:seedStoreOptions error:&seedStoreErrpr];

       NSDictionary *iCloudOptions =@{NSPersistentStoreUbiquitousContentNameKey: @"iCloud",
                                       NSMigratePersistentStoresAutomaticallyOption:@YES,
                                       NSInferMappingModelAutomaticallyOption:@YES
       };

       NSOperationQueue *queue=[[NSOperationQueue alloc] init];
       [queue addOperationWithBlock:^{
           NSError *error;
           [persistentStoreCoordinator migratePersistentStore:seedStore toURL:storeURL options:iCloudOptions withType:NSSQLiteStoreType error:&error];
           NSLog(@
           "Persistant store migrated");
           [kvStore setBool:YES forKey:@
           "SEEDED_DATA"];
          // [self checkForDuplicates];
       }];
   }else{
       NSError *error;
       NSDictionary *storeOptions =@{NSPersistentStoreUbiquitousContentNameKey: @
          "iCloud"
       };
       if (![persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType
                                        configuration:nil
                                        URL:storeURL
                                        options:storeOptions
                                        error:&error]) {
           NSLog(@
           "Unresolved error %@, %@", error, [error userInfo]);
           abort();
       }
   }

   return persistentStoreCoordinator;
}

- (NSURL *)applicationDocumentsDirectory{
   return [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory    inDomains:NSUserDomainMask] lastObject];
}

我能够通过指定iCloud驱动器目录(与developer.apple.com界面上的名称相同)来解决此错误.

-(NSURL *)cloudDirectory
{
NSFileManager *fileManager=[NSFileManager defaultManager];
NSString *teamID=@"iCloud";
NSString *bundleID=[[NSBundle mainBundle]bundleIdentifier];
NSString *cloudRoot=[NSString stringWithFormat:@"%@.%@",teamID,bundleID];
NSURL *cloudRootURL=[fileManager URLForUbiquityContainerIdentifier:cloudRoot];
NSLog (@"cloudRootURL=%@",cloudRootURL);
return cloudRootURL;
}

并将其作为NSPersistentStoreUbiquitousContentURLKey包含在icloudOptions字典中

NSDictionary *storeOptions =@{NSPersistentStoreUbiquitousContentNameKey: @"iCloud",
                                   NSPersistentStoreUbiquitousContentURLKey:[self cloudDirectory],
                                   };

我收到了一些奇怪的错误,所以我从所有设备中删除了应用程序,删除了iCloud驱动器文件,并在实际设备上重新运行,它运行正常.不确定它现在是否在IOS7上运行,但由于我只指定了NSPersistentStoreUbiquitousContentURLKey,我相信它应该没问题.
