I need to create two persistent stores, each with their own entities, with one persistent store coordinator. The hard part is, I want one persistent store to be linked to iCloud, but the other to only be a local store. I have read about making different configurations for the managed object model, but how do I fetch entities from the local store, rather than the iCloud enabled store? Here is my code so far, Am I headed in the right direction?:
NSMutableDictionary *options = [NSMutableDictionary dictionary];
[options setValue:[NSNumber numberWithBool:YES] forKey:NSMigratePersistentStoresAutomaticallyOption];
[options setValue:[NSNumber numberWithBool:YES] forKey:NSInferMappingModelAutomaticallyOption];
NSURL *cloudURL = [[NSFileManager defaultManager] URLForUbiquityContainerIdentifier:nil];
if (cloudURL)
{
NSLog(@"iCloud enabled: %@", cloudURL);
cloudURL = [cloudURL URLByAppendingPathComponent:@"FSListen"];
[options setValue:kICloudContentNameKey forKey:NSPersistentStoreUbiquitousContentNameKey];
[options setValue:cloudURL forKey:NSPersistentStoreUbiquitousContentURLKey];
}
else
{
NSLog(@"iCloud is not enabled");
}
// create the persistent store that will be connected to iCloud for favorites
NSURL *iClouldSoreURL= [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject];
iClouldSoreURL = [iClouldSoreURL URLByAppendingPathComponent:@"FSListen-iCloud.sqlite"];
NSError *error = nil;
NSPersistentStoreCoordinator *coordinator = [self.managedObjectContext persistentStoreCoordinator];
NSPersistentStore *store = [coordinator addPersistentStoreWithType:NSSQLiteStoreType
configuration:@"Default"
URL:iClouldSoreURL
options:options
error:&error];
if (!store)
{
NSLog(@"Error adding persistent store to coordinator %@\n%@", [error localizedDescription], [error userInfo]);
//Present a user facing error
}
// create the persistent store that will not be connected to iCloud for downloads
NSError *downloadsStoreError = nil;
NSURL *downloadsStoreURL = [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject];
downloadsStoreURL = [downloadsStoreURL URLByAppendingPathComponent:@"FSListen-Downloads.sqlite"];
NSPersistentStore *downloadsStore = [coordinator addPersistentStoreWithType:NSSQLiteStoreType
configuration:@"Downloads"
URL:downloadsStoreURL
options:nil
error:&downloadsStoreError];
if (!downloadsStore)
{
NSLog(@"ERROR CREATING DOWNLOADS STORE %@", downloadsStoreError.localizedDescription);
}
In my managed object model, I have one configuration with an entity called 'downloads' that I only want to be saved locally, but it is also in the default configuration, which I want to link to iCloud. How do I make sure I am saving my entities in the correct configuration?
