Cocoa Swift Message Actions API Reference for Realtime Apps

This SDK has been replaced by a new PubNub Swift SDK written purely in Swift. Check it out here

Add or remove actions on published messages to build features like receipts, reactions, or to associate custom metadata to messages. Clients can subscribe to a channel to receive message action events on that channel. They can also fetch past message actions from PubNub Storage independently or when they fetch original messages.

Add Message Action

Requires Storage & Playback add-on Requires that the Storage & Playback add-on is enabled for your key. See this page on enabling add-on features on your keys:
https://support.pubnub.com/hc/en-us/articles/360051974791-How-do-I-enable-add-on-features-for-my-keys-

Description

Add an action on a published message. Returns the added action in the response.

Method(s)

To Add a Message Action you can use the following method(s) in the Swift SDK:

1. open func addMessageAction(with: PNAddMessageActionRequest, completion: PNAddMessageActionCompletionBlock?)
   

   Parameter	Type	Required	Description
   request	PNAddMessageActionRequest	Yes	Add message action request with all information about new message action which will be passed to PubNub service.
   closure	PNAddMessageActionCompletionBlock	No	Add message action request completion closure.

PNAddMessageActionRequest

Parameter	Type	Required	Description
type	String	Yes	What feature this message action represents. Maximum 15 characters.
value	String	Yes	Value which should be added with message action type.
channel	String	Yes	Name of channel which stores the message for which action should be added.
messageTimetoken	NSNumber	Yes	Timetoken (PubNub's high precision timestamp) of message to which action should be added.

Basic Usage

let request = PNAddMessageActionRequest(channel: "chat", messageTimetoken: 1234567890)
request.type = "reaction"
request.value = "smile"

self.client.addMessageAction(with: request, completion: { status in
    if !status.isError {
        /**
         * Message action successfully added.
         * Created message action information available here: status.data.action
         */
    } else {
        if status.statusCode == 207 {
            // Message action has been added, but event not published.
        } else {
            /**
             * Handle add message action error. Check 'category' property to find out possible
             * issue because of which request did fail.
             *
             * Request can be resent using: status.retry()
             */
        }
    }
})
