SHDataKit

This is a suite of Objective-C classes and categories for Core Data that offers a different and we thing much simpler paradigm for Core Data programming for Mac OS X and iPhone OS. It was developed for the Shorthand iOS app.

Using SHDataKit

Add the files to your Xcode project:

SHDataKit.h
NSManagedObjectContext+SHDataKitAdditions.h
NSManagedObjectContext+SHDataKitAdditions.m
SHManagedObject+SHDataKitAdditions.h
SHManagedObject+SHDataKitAdditions.m	
SHDataAdapter.h
SHDataAdapter.m

##Import the header where you need to access Core Data:##

#import "SHDataKit.h"

##Create a DataAdapter from the Post Model:##

SHDataAdapter *postAdapter = [Post dataAdapter];

##Inert a new post object##

Post *post = [postAdapter insert];
post.subject = @"Post 1";
post.content = @"This is my first post";

NSError *error;
if (![post saveObject:error])
{
	// Show error
}

##Fetch all Post Objects##

NSArray *posts = [postAdapter fetchAll];

##Fetch select Post Objects and sort them##

NSArray *posts = [postAdapter fetchAllWithPredicate:[NSPredicate predicateWithFormat:@"enabled = 1"]
							              sortDescriptor:[NSSortDescriptor sortDescriptorWithKey:@"order" ascending:YES]];

##Get the count for the Post entity##

NSInteger postCount = [postAdapter count];

##Using SHKit in a background thread##

NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

NSManagedObjectContext *managedObjectContext = [NSManagedObjectContext managedObjectContextPreppedForMerge];

SHDataAdapter *postAdapter = [Post dataAdapterWithManagedObjectContext:managedObjectContext];

Post *post = [postAdapter insertWithValues:[NSDictionary dictionaryWithObjectsAndKeys:@"Post 1", @"post", nil]];
post.content = @"This is my first post";

[managedObjectContext save:nil];

[pool drain];
