CoreDataMate

CoreDataMate is a lightweight CoreData assistant. It gives you all of the control of CoreData, but helps you manage it.

Installation

CoreDataMate is available through CocoaPods, to install it simply add the following line to your Podfile:

pod "CoreDataMate"

Use

Setup

Setup your Core Data store in your UIApplicationDelegate during your application's launch:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    [CDMDataManager setupWithDataModelName:@"ModelName" storeName:@"StoreName" persistenceType:NSSQLiteStoreType];

    // Perform any other necessary setup

    return YES;
}

Main Queue Work

If you need to perform operations on the main queue, grab the mainContext from the CDMDataManager and perform your actions. After you are finished, simply persist the CDMDataManager instance.

NSManagedObjectContext *context = [[CDMDataManager sharedManager] mainContext];

// Perform main queue operations

[[CDMDataManager sharedManager] persist:YES];

Background Queue Work

If you need to perform operations on a background queue, create a temporary NSManagedObjectContext in your background queue and set it's parent context to CDMDataManager's mainContext. You can then perform your actions. Once you are finished, save your temporary context. After your temporary context is persisted, persist the CDMDataManager instance.

NSManagedObjectContext *temporaryContext = [[NSManagedObjectContext alloc] initWithConcurrencyType:NSPrivateQueueConcurrencyType];
[temporaryContext setParentContext:[[CDMDataManager sharedManager] mainContext]];

// Perform background queue operations

// This call writes your changes to CDMDataManager's mainContext
BOOL successfulSave = [temporaryContext save:&error];
if ( successfulSave )
{
  // This call writes your changes to the store
  [[CDMDataManager sharedManager] persist:YES];
}

Remember: Your data is not fully persisted until the CDMDataManager instance is persisted. This persist call is the permanent persist call.
