DrippsOperation is a project mainly written in Objective-C, it's free.
Provides an easy way to manage Core Data changes on background threads in iOS
A quick and easy way to manage CoreData on background threads in iOS 4.0 and higher.
Subclass DrippsOperation and add a "- (void)main" function to your implementation. The operation's NSManagedObjectContext is stored in an instance variable named "nsmoc". This should be the only context used throughout all the code being executed in the operation. When you're finished just call [self saveChanges]; to save the context and you're done.
You can add DrippsOperation subclasses to any NSOperationQueue, but I have also provided DrippsQueueManager to help manage multiple queues. I often find myself with the need for synchronous and asynchronous queues in the same project. While I could take the time to set up dependencies to achieve the same thing, many times my operations are completely unrelated and it's much quicker to create a queue with a max concurrency of 1 for the synchronous queues and completely separate queues for asynchronous operation queues.
Please feel free to fork this project or suggest enhancements by emailing me at the address below.
