ItemsDataSource

Build Status CocoaPods Platform

ItemsDataSource is a generic datasource for UICollectionView.

Features

  • Create collections with any data types
  • Reusable UICollectionViewCell and UICollectionReusableView
  • UICollectionView at its core
  • Easy extendable

Requirements

  • iOS 10.0+
  • Xcode 9.0+
  • Swift 5.0+

Installation

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods

CocoaPods 1.1+ is required to build ItemsDataSource.

To integrate ItemsDataSource into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '10.0'
use_frameworks!

target '<Your Target Name>' do
    pod 'ItemsDataSource'
end

if you're using CocoaPods 1.5.0+ you can include ItemsDataSource as static library:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '10.0'

target '<Your Target Name>' do
    pod 'ItemsDataSource'
end

Then, run the following command:

$ pod install

Carthage

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate ItemsDataSource into your Xcode project using Carthage, specify it in your Cartfile:

github "ItemsDataSource"

Run carthage update to build the framework and drag the built ItemsDataSource.framework into your Xcode project.

Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler. It is in early development, but ItemsDataSource does support its use on supported platforms.

Once you have your Swift package set up, adding ItemsDataSource as a dependency is as easy as adding it to the dependencies value of your Package.swift.

Swift 4

dependencies: [
    .package(url: "https://github.com/minikin/ItemsDataSource.git")
]

Manually

If you prefer not to use any of the aforementioned dependency managers, you can integrate ItemsDataSource into your project manually. Just copy files from Sources folder to your projects:

CellDescriptor.swift
Groupable.swift
Itemable.swift
ItemsDataSource.swift
SupplementaryDescriptor.swift

Usage

Define your model as usual

import UIKit
import ItemsDataSource

struct Vitamin {

  // MARK: - Instance Properties

  let name: String
  let amount: Double
}

Conform your model to Itemable

extension Vitamin: Itemable {
  var itemCellDescriptor: CellDescriptor {
    return CellDescriptor(reuseIdentifier: ReuseIdentifier.vitaminCell, configure: configureIngredientCell)
  }
}

Add configure method to model in extension

extension Vitamin {
  func configureIngredientCell(_ cell: ViataminCell) {
    cell.vitaminNameLabel.text = name
    cell.backgroundColor = UIColor.randomColor()
  }
}

In ViewController inject your datasource

import ItemsDataSource
import UIKit

final class ExampleViewController: UIViewController {

  // MARK: - Injections

  public var vitaminsDataSourse = ItemsDataSource(items: [Vitamin](),
                                                  cellDescriptor: { $0.itemCellDescriptor })

  // MARK: - IBOutlets

  @IBOutlet var exampleCollectionView: UICollectionView! {
    didSet {
      setExampleCollectionViewDataSource()
      exampleCollectionView.delegate = self
      setExampleCollectionViewLayout()
      exampleCollectionView.reloadData()
    }
  }

  // MARK: - Instance Properties

  var vitamins = [Vitamin]()

  // MARK: - ViewController LifeCycle

  override func viewDidLoad() {
    super.viewDidLoad()
    print("vitamins", vitamins)
  }

  // MARK: - Helpers

  private func setExampleCollectionViewDataSource() {
    vitaminsDataSourse.items = vitamins
    exampleCollectionView.dataSource = vitaminsDataSourse
  }

  private func setExampleCollectionViewLayout() {
    let layout = CommonFlowLayout(columns: 2,
                                  itemHeight: 200,
                                  inset: 5,
                                  spacing: 0,
                                  lineSpacing: 5)
    exampleCollectionView.collectionViewLayout = layout
  }
}

// MARK: - UICollectionViewDelegate

extension ExampleViewController: UICollectionViewDelegate {}
