我encrypted-core-data用来加密所有持久化的数据,以前很简单CoreData.persistentStoreCoordinator创建代码如下.

- (NSPersistentStoreCoordinator *)persistentStoreCoordinator {
if (_persistentStoreCoordinator != nil) {
    return _persistentStoreCoordinator;
}

NSURL *oldStoreURL = [[self applicationDocumentsDirectory] URLByAppendingPathComponent:@"VistaJetApp.sqlite"];
NSURL *newStoreURL = [[self applicationDocumentsDirectory] URLByAppendingPathComponent:@"VistaJet.sqlite"];
NSError *error = nil;

NSString *currentPassword = [[VJAesCryptoWrapper getInstance] getCurrentPassword];
NSDictionary *options = [self getEncryptedStoreOptionsWithPassword:currentPassword andDatabaseStore:newStoreURL];

_persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:[self managedObjectModel]];

//if old store not exists , it means fresh installation
if([[NSFileManager defaultManager] fileExistsAtPath:oldStoreURL.path] == NO) {             
    if (![_persistentStoreCoordinator addPersistentStoreWithType:EncryptedStoreType configuration:nil URL:newStoreURL options:options error: &error]) {         
    }        
} …
