DESCRIPTION

The TPMigrationManager class provides easy way for
CoreData migration.

There are two migration ways.

  • Inferred mapping model migration.
  • Specific mapping model migration.

‘Inferred mapping model migration’ is an easy and fast
migration way. You can use this way with
migrateByInferredMappingModelWithOptions:completed: method.

Fot this way, you don’t need to prepare any migration
model. CoreData framework checks the differences between
old and new model and tries to migrate automatically. It
is Apple’s recommendation. If model is not changed so
much, you should use this way. For this migration way, you
cannot terminate the migration process by cancel method
and migrationProgress property is not changed at all.

‘Specific mapping model migration’ is a flexible migration
way. You can use this way with
migrateBySpecificMappingModelWithOptions:progress:completed:
method.

With this way, you can convert any old model to new one by
offering specific migration model by yourself. You can
terminate the migration process anytime by cancel method,
and migrationProgress property will be updated
periodically.

Before starting migration, you should use migrationStatus
for checking which migration way you can use in your
environment.

During migration, temporary persistent store file is
created and the file is used for migration. After
migration completed, the temporary persistent overwites old
one. If migration is terminated by cancel method or failed
by error, old persistent remains as it is. If you’d like
to remain old persistent file, you can specify
TPMigrationManagerBackupPersistentStoreExtensionOption
option in migration method.

After completing the migration, the existing persistent
store is replaced to new one regardless of whether you use
TPMigrationManagerBackupPersistentStoreExtensionOption
option or not. If you already have a
NSManagedObjectContext object which is dedicated to old
persistent store, you have to recreate it for new store.

PLATFORM

iOS 5 and above. You have to enable ARC.
