NSManagedObjectContext-Hydrate 1.0.4

By

Have you ever wanted to preload an application's CoreData store?
If you did, you must know then that it's a real painful and undocumented process. You probably tried different techniques like using Python or Ruby scripts, but it should be easier than that!

This category class helps you by parsing and saving automagically every object from a JSON or CSV data structure into a persistent store with no effort.

Installation

Available in Cocoa Pods

pod 'NSManagedObjectContext-Hydrate', '~> 1.0.3'

How to use

Check out the Doc Set

Step 1

#import <CoreData/CoreData.h>
#import "NSManagedObjectContext+Hydrate.h"

Step 2

After initialising your Managed Object Context, you are ready to preload your JSON content into the store. Call the following method:

NSString *path = [[NSBundle mainBundle] pathForResource:@"persons" ofType:@"json"];
NSDictionary *attributes = @{@"firstName":@"first_name", @"lastName":@"last_name", @"age":@"age", @"height":@"height", @"weight":@"weight"};

[_managedObjectContext hydrateStoreWithJSONAtPath:path attributeMappings:attributes forEntityName:@"Person"];

Or your CSV content:

NSString *path = [[NSBundle mainBundle] pathForResource:@"persons" ofType:@"csv"];
NSDictionary *attributes = @{@"firstName":@"first_name", @"lastName":@"last_name", @"age":@"age", @"height":@"height", @"weight":@"weight"};

[_managedObjectContext hydrateStoreWithCSVAtPath:path attributeMappings:attributes forEntityName:@"Person"];
