Platform

This library is currently WIP.

Example

To run the example project, clone the repo, and run pod install from the Example directory first.

Usage

This library is a light data source implementation for RxRealm. It allows you to easily bind an Observable sequence of Realm objects to a table or a collection view. The library is both iOS and macOS compatible.

Binding to a table view

Check out the included demo app to see this in action.

// create data source
let dataSource = RxTableViewRealmDataSource<Lap>(cellIdentifier: "Cell", cellType: PersonCell.self) {cell, ip, lap in
    cell.customLabel.text = "\(ip.row). \(lap.text)"
}

// RxRealm to get Observable<Results>
let realm = try! Realm(configuration: DataRandomizer.realmConfig)
let laps = Observable.changeset(from: realm.objects(Timer.self).first!.laps)
    .share()

// bind to table view
laps
    .bindTo(tableView.rx.realmChanges(dataSource))
    .disposed(by: bag)

Binding to a collection view

Check out the included demo app to see this in action.

// create data source
let dataSource = RxCollectionViewRealmDataSource<Lap>(cellIdentifier: "Cell", cellType: LapCollectionCell.self) {cell, ip, lap in
    cell.customLabel.text = "\(ip.row). \(lap.text)"
}

// RxRealm to get Observable<Results>
let realm = try! Realm(configuration: DataRandomizer.realmConfig)
let laps = Observable.changeset(from: realm.objects(Timer.self).first!.laps)
    .share()

// bind to collection view
laps
    .bindTo(collectionView.rx.realmChanges(dataSource))
    .disposed(by: bag)

Reacting to cell taps

The library adds an extension to table views and collection views, allowing you to easily subscribe to the cell selected delegate event. Here’s a snippet from the example demo app:

tableView.rx.realmModelSelected(Lap.self)
  .map({ $0.text })
  .bind(to: rx.title)
  .disposed(by: bag)

Installation

This library depends on RxSwift, RealmSwift, and RxRealm.

CocoaPods

RxRealm is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "RxRealmDataSources"

TODO

  • Test add platforms and add compatibility for the pod
