NSExpressionDescription |
Descriptor for a fetch result column that does not appear in the source, such as a sum or a minimum of a column in the source. |
NSFetchedPropertyDescription |
Holds "fetched properties," that allow the developer to specify related objects via a weak unidirectional relationship in a fetch request. |
NSFetchedResultsController |
Controller object for Core Data fetch requests; generally used to provide data for a UITableView. |
NSFetchedResultsControllerDelegate |
Delegate object for NSFetchedResultsController objects, provides methods relating to fetch results adding, removing, moving, or updating objects. |
NSFetchedResultsControllerDelegate_Extensions |

NSPersistentStoreCoordinatorStoreChangeEventArgs |
Provides data for the event. |

Descriptor for a persistent store inside a persistent container. |
NSPersistentStoreRequest |
Criteria used to retrieve data from or save data in a persistent store. |
NSPersistentStoreResult |
Class that represents the result of request that was made of a persistent data store. |
NSPropertyDescription |
Defines properties of an entity in a managed objectmodel. The equivalent of an instance property. |
NSPropertyMapping |
Maps a property between source and destination entities. |
NSQueryGenerationToken |
Controls whether and how a managed object context pins itself to database transactions. |
NSRelationshipDescription |
Describes the relationships of a NSEntityDescription object. |
NSSaveChangesRequest |
A collection of changes to be made by an object store. |
UserInfo |
Contains Core Data error information. |
UserInfoKeys |
Contains keys for error information that Core Data stores in a dictionary. |
Interfaces
INSFetchedResultsControllerDelegate |
Interface representing the required methods (if any) of the protocol NSFetchedResultsControllerDelegate. |
