CoreData stack and controller that will never block UI thread
HardCoreData is a yet another core data stack based on Marcus Zarra's multithreading approach. This smart approach uncouples the writing into its own private queue and keeps the UI smooth as button.
HardCoreData consists of two fundamentals: HCDCoreDataStack and HCDCoreDataStackController.
Incapsulates native CoreData stack setup.
/* Convenience initializers */
/**
Since HCDCoreDataStack is a protocol as well as a class, you can create your own custom stacks, by implementing protocol.
@protocol HCDCoreDataStack@required
/* Represents current store coordinator */ @property (nonatomic, strong, readonly) NSPersistentStoreCoordinator *persistentStoreCoordinator;
/* Represents currentm object model */ @property (nonatomic, strong, readonly) NSManagedObjectModel *managedObjectModel;
/* Represents your single source of truth. Associated with main queue. */ @property (nonatomic, strong, readonly) NSManagedObjectContext *mainManagedObjectContext;
@end
The controller to instantiate child MOCs and save the while chain to the persistent store.
/** * Designated initializer * * @param stack HCDCoreDataStack * * @return HCDCoreDataStackController */ - (instancetype)initWithStack:(id )stack NS_DESIGNATED_INITIALIZER;/**
/**
/* Create core data stack */ HCDCoreDataStack *stack = [HCDCoreDataStack sqliteStackWithName:@"Model"]; HCDCoreDataStackController *coreDataController = [HCDCoreDataStackController controllerWithStack:stack];NSManagedObjectContext *backgroundContext = [coreDataController createChildContextWithType:NSPrivateQueueConcurrencyType]; [backgroundContext performBlock:^{
Person *person = [NSEntityDescription insertNewObjectForEntityForName:NSStringFromClass([Person class]) inManagedObjectContext:backgroundContext]; person.firstName = @"John"; person.lastName = @"Doe"; /* Save child context */ [backgroundContext save:nil]; /* Save data to store */ [coreDataController save];
}];
