Easiest way to implement reactions in iOS app

Reactions iOS

Recently, we were working on a social app of one of our clients. Their requirement was to add reactions feature in the app and especially Facebook Reactions. To integrate Facebook Reactions iOS in the app was a great experience for our team. In this guide, we will give you a detailed information about integrating the Facebook Reactions platform in your iOS iPhone app.

Reactions are an extension of the Like Button to give people more ways to share their reaction to a post in a quick and easy way. The collection of Reactions includes Like, Love, Haha, Wow, Sad and Angry.

To ensure accurate and consistent use, never alter, rotate, embellish or attempt to recreate the Reactions. Never alter the proportions and shape of the Reactions (and surrounding UI) for any reason.

What are reactions iOS?

Reactions are not emojis or individual icons, and they cannot be used in this way. It’s important to show Reactions in the way they are intended to be used on Facebook – as a quick and easy way to express how you feel. Reactions are line-up of emoji that allow you to react to posts with six different animated emotions:Love, Haha, Wow, Sad, Angry, and, the classic Like.

When a Like simply won’t do

After years of requests for a “dislike” option, Its Reactions which  give users a more nuanced way of expressing their sentiments to posts. Because let’s face it, some life events aren’t befitting of a Like (deaths, break-ups, disappointing election outcomes, etc.).

How do Reactions iOS work?

Reactions work in the same way as the original Like button and appear on any post.To choose the reaction you want, simply hold down the Like button (or hover with your mouse if viewing from a desktop) and a menu will appear showing the six reactions.Once you add your reaction, it’s lumped together with the Likes and other reactions under the post. You can only add one reaction per post (e.g. you can’t Love and Haha a post at the same time).

Reactions iOS design

An enormous, but perhaps less obvious part of Reactions’ success is owed to their design. Reaction’s design has two key principles:

  1. Reactions should be universally understood. So more people can connect and communicate together.
  2. Reactions should be widely used and expressive. To allow people to express themselves in ways they would in real life.

What about dislikes?

Wondering why human beings doesn’t make life easier for themselves by just giving into the many requests for a simple thumbs-down button?

“Binary ‘like’ and ‘dislike’ doesn’t properly reflect how we react to the vast array of things we encounter in our real lives

How do Reactions iOS impact the feed?

“Over the past year we’ve found that if people leave a Reaction on a post, it is an even stronger signal that they’d want to see that type of post than if they left a Like on the post. So we are updating News Feed to weigh reactions a little more than Likes when taking into account how relevant the story is to each person.”


Steps to Implement Reactions iOS in App:


Step1: Pod installation in App including the pod in pod file

pod 'Reactions'

  Write the above code in pod file and run the command pod install

Step2 : Import the the Reaction module and Iimplement delegate method in your class where you want to use

"import Reactions"

Step3: Initialise the class:

"let myReaction = Reaction(id: "like", title: "Like", color: .black, icon: UIImage(named: "yourImageName")!)

Step4 : Create an outlet of facebookReaction button , set the initial value and a Closure to notify the value of reaction has ben changed:

var reactionSelected: ((_ reactionName:String, _ cell: UITableViewCell) -> Void)?
@IBOutlet weak var facebookReactionButton: ReactionButton! {
        didSet {
            let selector       = ReactionSelector()
            selector.reactions = Reaction.facebook.all
            facebookReactionButton.reactionSelector = selector
            // React to reaction change
            selector.addTarget(self, action: #selector(reactionDidChanged), for: .valueChanged)
            facebookReactionButton.config    = ReactionButtonConfig() {
                $0.iconMarging      = 4
                $0.spacing          = 4
                $0.font             = UIFont(name: "HelveticaNeue", size: 13)
                $0.neutralTintColor = .black
                $0.alignment        = .centerLeft
            facebookReactionButton.reactionSelector?.feedbackDelegate = self

public func reactionFeedbackDidChanged(_ feedback: ReactionFeedback?) {
        let text = feedback?.localizedString
        print("Text Is --- ",text ?? "")

Step5 : Set default value on reaction button, Make default button active and Method for text change:

"let myReaction = Reaction(id: "like", title: "Like", color: .black, icon: UIImage(named: "yourImageName")!)
        facebookReactionButton.reaction = myReaction
        facebookReactionButton.config.neutralTintColor = .black
        facebookReactionButton.isSelected = false"
"self.facebookReactionButton.isUserInteractionEnabled = enable"

func reactionDidChanged(_ sender: ReactionSelector) {
        let reactionID = sender.selectedReaction?.id
        print("Selected Reaction -- ",sender.selectedReaction?.id ?? "Default")
        reactionSelected?(reactionID ?? "like",self)

Step6 : To update the reaction on reaction button use the method:

func setReactionsFor(_ feed:ActivityFeeds){
        facebookReactionButton.isSelected = true
        switch feed.reactionName {
        case "haha":
            facebookReactionButton.reaction = Reaction.facebook.haha
        case "love":
            facebookReactionButton.reaction = Reaction.facebook.love
        case "wow":
            facebookReactionButton.reaction = Reaction.facebook.wow
        case "sad":
            facebookReactionButton.reaction = Reaction.facebook.sad
        case "angry":
            facebookReactionButton.reaction = Reaction.facebook.angry
