KSCoreDataObserver 1.2.2

You want to add pod 'KSCoreDataObserver', '~> 1.2' similar to the following to your Podfile:

target 'MyApp' do
  pod 'KSCoreDataObserver', '~> 1.2'
end

Then run a pod install inside your terminal, or from CocoaPods.app.

Alternatively to give it a test run, run the command:

pod try KSCoreDataObserver

KSCoreDataObserver 1.2.2

By

This is a tiny library to manage CoreData notifications in order to update the user interface when a NSManagedObject is either inserted, deleted or updated.

KSCoreDataObserver works a bit like NSFetchedResultsController, that is by observing the managed object context's NSManagedObjectContextObjectsDidChangeNotification.

Whenever a change event occurs, a block is called that allows you to update your user interface accordingly.

Installation

Use CocoaPods to add KSCoreDataObserver to your project. Just add the following line to your Podfile.

pod 'KSCoreDataObserver', '~> 1.2.2'

Example

KSCoreDataObserver *observer = [[KSCoreDataObserver alloc] initWithContext:aNSManagedObjectContext];
[observer setRequiredContext:nil]; // optional to observe ALL NSManagedObjectContexts - be careful with threading!
[observer setObservedObject:aManagedObject]; // optional to observe a specific NSManagedObject
[observer setObservedEntityName:@"EntityName"]; // optional to observe objects of a specific entity
[observer setPredicate:[NSPredicate predicateWithFormat:@"attribute = 123"]]; // optional to set a user defined filter for observed objects
[observer setMask:KSObserverTypeUpdated | KSObserverTypeDeleted]; // optional to only observe specific event types

observer.objectDidChangeBlock = ^(KSObserverType type, NSManagedObject *object, NSArray *changes) {
    // do whatever is necessary to update your user interface
};
