static dispatch_once_t token;
dispatch_once(&token, ^{
// get the model
NSManagedObjectModel *model = [NSManagedObjectModel mergedModelFromBundles:nil];
// get the coordinator
coordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:model];
// add store
NSFileManager *fileManager = [NSFileManager defaultManager];
NSURL *applicationSupportURL = [[fileManager URLsForDirectory:NSLibraryDirectory inDomains:NSUserDomainMask] lastObject];
[fileManager createDirectoryAtURL:applicationSupportURL withIntermediateDirectories:NO attributes:nil error:nil];
NSURL *databaseURL = [applicationSupportURL URLByAppendingPathComponent:@"database_name.sqlite"];
NSError *error = nil;
// [[NSFileManager defaultManager] removeItemAtURL:databaseURL error:&error];
NSDictionary *options = @{
EncryptedStorePassphraseKey : @"********",
