Core Data Controller to simplify setting up a Core Data stack.

Installation with CocoaPods

Add

pod 'TKCoreDataController'

to your Podfile.

Managed object contexts

For convinience TKCoreDataController has mainObjectContext set up in NSMainQueueConcurrencyType on it’s persistent store coordinator.

If you need more contexts adding should be done like this:

TKCoreDataController *controller = // ...
NSMangedObjectContext *context = [[NSMangedObjectContext alloc] initWithConcurrencyType:NSPrivateQueueConcurrencyType];
[context performBlock:^{
    context.persistentStoreCoordinator = controller.persistentStoreCoordinator;
}];

Migration handling

As migrations can possibly run a long time you should be careful when adding them, to not block the UI. This is especially problematic during application startup, as iOS will kill your app if it takes to long to start.

Typically the flow looks like this (error handling omnited):

TKCoreDataController *controller = // ...
NSURL *storeURL = // ...

if ([controller  isMigrationRequiredForAddingStoreAtURL:storeURL error:NULL]) {
    [controller addPersistentStoreAtURL:storeURL
                      withConfiguration:nil
                                options:nil
                                  queue:NULL
                       migrationHandler:^(BOOL migrationRequired, NSError *error) {
                         if (migrationRequired) {
                            // show migration URL
                         }
                       }
                       resultHandler:^(NSPersistentStore *store, NSError *error){
                           // hide migration UI, show app UI
                       }];
} else {
    [controller addPersistentStoreAtURL:storeURL
                      configurationName:nil
                                options:nil
                                  error:NULL];
}
