AECoreDataUI

Super awesome Core Data driven UI for iOS written in Swift

AECoreDataUI was previously part of AERecord, so you may want to check that also.

When it comes to connecting your data with the UI, the best approach is to use NSFetchedResultsController. CoreDataTableViewController wrapper from Stanford's CS193p is so great at it, that I've written it in Swift and made CoreDataCollectionViewController too in the same fashion.

Features

• Core Data driven UITableViewController (UI automatically reflects data in Core Data model)
• Core Data driven UICollectionViewController (UI automatically reflects data in Core Data model)

Usage

You can also check demo project in AERecord.

CoreDataTableViewController

CoreDataTableViewController mostly just copies the code from NSFetchedResultsController documentation page into a subclass of UITableViewController.

Just subclass it and set it's fetchedResultsController property.

After that you'll only have to implement tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell and fetchedResultsController will take care of other required data source methods. It will also update UITableView whenever the underlying data changes (insert, delete, update, move).

Example

import UIKit
import CoreData

class MyTableViewController: CoreDataTableViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "Cell")
        refreshData()
    }

    func refreshData() {
        let sortDescriptors = [NSSortDescriptor(key: "timeStamp", ascending: true)]
        let request = Event.createFetchRequest(sortDescriptors: sortDescriptors)
        fetchedResultsController = NSFetchedResultsController(fetchRequest: request, managedObjectContext: AERecord.defaultContext, sectionNameKeyPath: nil, cacheName: nil)
    }

    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as UITableViewCell
        if let frc = fetchedResultsController {
            if let object = frc.objectAtIndexPath(indexPath) as? Event {
                cell.textLabel.text = object.timeStamp.description
            }
        }
        return cell
    }

}

CoreDataCollectionViewController

Same as with the tableView.

Requirements

• Xcode 7.3+
• iOS 8.0+

Installation

• Using CocoaPods:

  pod 'AECoreDataUI'

• Carthage:

  github "tadija/AECoreDataUI"
  

• Manually:

  Just drag AECoreDataUI.swift into your project and start using it.
