Introduction

Welcome to the documentation for the DJFetchedResultsController framework!
This framework is designed to simplify the implementation of NSFetchedResultsController and provide a convenient way to manage data displayed in table or collection views. Whether you are new to iOS development or an experienced developer, this documentation will guide you through the setup and usage of the framework.

Installation

To install DJFetchedResultsController, you have the following options:

  1. Manual Installation: You can manually download the source code by visiting the GitHub repository and then add the framework to your project.
  2. CocoaPods: You can use CocoaPods to manage your dependencies. Simply add the following line to your Podfile:
    pod 'DJFetchedResultsController'
  3. Swift Package Manager: If you prefer to use the Swift Package Manager, add the package as a dependency in your Package.swift file:
    .package(url: "https://github.com/yourlink", .upToNextMajor(from: "1.0.0"))

Getting Started

Before using DJFetchedResultsController, you should have a basic understanding of Core Data and how to set up a Core Data stack in your application. Once you have a Core Data stack, follow the steps below to integrate the framework into your project:

Step 1: Add the Framework

  1. Drag and drop the DJFetchedResultsController.framework into your Xcode project.
  2. In the project settings, select your app target, navigate to the General tab, and add the framework under the Frameworks, Libraries, and Embedded Content section.

Step 2: Import the Framework

At the top of your Swift file, import the framework using the following statement:
import DJFetchedResultsController

Step 3: Configure the Fetched Results Controller

Initialize a new instance of DJFetchedResultsController with the desired NSFetchRequest and NSManagedObjectContext objects. You can also provide optional parameters such as sorting descriptors or a section key path as needed.

Step 4: Implement the Protocol

Conform to the DJFetchedResultsControllerDelegate protocol in your view controller and implement the required methods to update your table or collection view with the fetched data.

Example Code

Below is an example of how to set up and use DJFetchedResultsController in your project:


// Import the framework
import DJFetchedResultsController

// Configure the fetched results controller
let fetchRequest = NSFetchRequest(entityName: "YourEntityName")
let context = // Obtain your NSManagedObjectContext instance
let fetchedResultsController = DJFetchedResultsController(fetchRequest: fetchRequest, managedObjectContext: context)

// Implement the protocol methods
class YourViewController: UIViewController, DJFetchedResultsControllerDelegate {

// Table or collection view outlet
@IBOutlet weak var tableView: UITableView!

override func viewDidLoad() {
super.viewDidLoad()

// Set the delegate
fetchedResultsController.delegate = self

// Perform the initial fetch
try? fetchedResultsController.performFetch()
}

// Delegate method to update data in the table view
func controllerDidChangeContent(_ controller: DJFetchedResultsController) {
tableView.reloadData()
}
}

Conclusion

Congratulations! You have successfully integrated DJFetchedResultsController into your project and learned the basic usage of the framework. You can now efficiently manage your fetched data and keep your table or collection view in sync with Core Data changes. Feel free to explore the additional features and customization options provided by the framework to further enhance your application.
