TFCoreDataExtras simplifies Core Data usage. Most things assume you've created class files from your model. It helps you:

• Set up new managed object contexts (loading the store and model for you). +managedObjectContextFromModelNamed:storeName:type: loads a model with the specified name from your Resources and associates it with a store from Application Support.
• Create objects. -initWithEntity:insertIntoManagedObjectContext: is now -initInsertingIntoManagedObjectContext: – the entity is looked up automatically.
• Find objects. In most cases, you no longer need to create fetch requests. Send +objectsInManagedObjectContext:sortedBy:ascending:matchingPredicateFormat: (or one of the related methods) to your NSManagedObject subclass.

Example

NSArray *people = [MYPerson objectsInManagedObjectContext:moc sortedBy:@"firstName" ascending:YES matchingPredicateFormat:@"city = %@", @"Boston"];

Without TFCoreDataExtras:

NSFetchRequest *req = [[NSFetchRequest alloc] init];
[req setEntity:[NSEntityDescription entityForName:@"Person" inManagedObjectContext:moc]];
[req setSortDescriptors:[NSArray arrayWithObject:[NSSortDescriptor sortDescriptorWithKey:@"firstName" ascending:YES]]];
[req setPredicate:[NSPredicate predicateWithFormat:@"city = %@", @"Boston"]];
NSArray *people = [moc executeFetchRequest:req error:NULL];
