ACKReactiveExtensions

ACKReactiveExtensions is set of useful extensions for ReactiveCocoa you could use in your apps.

Currently we have extensions for

• AlamofireImage
• Argo
• Marshal
• Reachability
• Realm
• SDWebImage
• UIKit
• WebKit

If you'd love to have more extensions available just open an issue or even better create a pull request!

Installation

ACKReactiveExtensions is available through CocoaPods. Simply add the following line to your Podfile:

pod "ACKReactiveExtensions"

Subspecs

By using pod "ACKReactiveExtensions" you will get only general and UIKit extensions but there are also subspecs you can like/need.

pod 'ACKReactiveExtensions/AlamofireImage'
pod 'ACKReactiveExtensions/Argo'
pod 'ACKReactiveExtensions/Marshal'
pod 'ACKReactiveExtensions/Reachability'
pod 'ACKReactiveExtensions/Realm'
pod 'ACKReactiveExtensions/SDWebImage'
pod 'ACKReactiveExtensions/WebKit'

These subspecs mostly require aditional dependencies (as Argo or Reachability) and you could not need it for your project. That's why it is separated to subspecs.

Usage

Usage is really simple, ACKReactiveExtensions contains just more extensions for ReactiveSwift's Reactive struct so it can be used on more objects.

let imageURL: Property<URL> = ...
let imageView = UIImageView()

imageView.reactive.imageURL <~ imageURL

Mapping extensions

ACKReactiveExtensions contains reactive mapping extensions for following libraries. See their page for more information.

• Argo extensions
• Marshal extensions

Mapping configuration

In general we are against mapping objects on main thread (and you should be too), but you know, you only live once so we still give you the opportunity to do so. By default our mapping extensions allow this behavior but if you want to restrict that, you can do that by setting a configuration variable.

ACKReactiveExtensionsConfiguration.allowMappingOnMainThread = false

From now on the mapping extensions will expect to be called on background thread, but don't worry, we use asserts so your production users are safe from crashing if somehow things don't go as good as expected.

UITextField/UITextView two way binding

ACKReactiveExtensions contains special <~> two way binding operator which will create binding between MutableProperty and your UITextField/UITextView.

Until now all those bindings looked like this

let textProperty: MutableProperty<String?> ...
let textField: UITextField ...

textField.reactive.text <~ textProperty
textProperty <~ textField.reactive.continousTextValues

From now on you can use the <~> operator

textProperty <~> textField

The <~> operator is commutative so the order of operands doesn't matter.
