FFDataPersistence

A helper class that simplifies application interaction with CoreData.

Setup

Add the following to your plist:

[[NSBundle mainBundle] infoDictionary][@"Data Persistence"][@"Manage Object Model"];
[[NSBundle mainBundle] infoDictionary][@"Data Persistence"][@"Database Name"];

Then on your .pch file add the following:

// If you're using a configuration class
#import "FFConfiguration.h"

#import "FFDataPersistence.h"
#import "FFDataPersistence+Setup.h"
#import "FFDataPersistence+Saving.h"
#import "NSManagedObject+FFDataPersistence.h"

Also make sure that CoreData is included in your project:

#ifdef __OBJC__
    #import <UIKit/UIKit.h>
    #import <Foundation/Foundation.h>
    #import <CoreData/CoreData.h>
#endif

You can optionally insert this to your app delegate to manually start the managed object context:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    FFDataPersistence *dataPersistence = [FFDataPersistence sharedInstance];
    [dataPersistence start];
    
    return YES;
}

Usage

To instantiate a new NSManagedObject

NSManagedObject *myObj = [NSManagedObject initInDataPersistenceContext];

This method returns an NSManagedObject which you can set attributes for

[myObject setAttribute:@"a value"];

Then when you are done manipulating your NSManageObject you can save the current context

[myObject save];

or

[myObject saveAndWait];
