The latest iPhone firmware iOS 10 (as of writing, still in beta) has new iMessage functions which includes Sticker Packs. See https://developer.apple.com/imessage/. Stickers come in the form of standalone Sticker Pack App, but also as an Extension to your existing app.

This plugin adds an iMessage Stickers App Extension to your existing Cordova/Cocoon.io project. XCode 8 is required (as of writing, also still in beta).

1. First, prepare a sticker pack (see below).
2. Install the plugin by

$ cordova plugin add https://github.com/LuckyKat/cordova-sticker-pack-extension

Or if using Cocoon.io, add the plugin by Plugins -> Custom -> Git url The Sticker Pack will be copied from the www folder during the plugin install.

Note: please install the plugin via git and not npm package, until I figure out how to perform npm install during a cordova install.

3. Compile the project with XCode 8.

The easiest way to do this is by installing XCode 8 and creating a Sticker App Extension. The resulting .xcassets and Info.plist can then be used as Sticker Pack for the Cordova project. You could also do this by hand if you know which json files to create.

Place the .xcasset and Info.plist in a folder named YOUR_PROJECT_NAME Stickers and place this in the www folder.

The bundle id of the sticker pack will be YOUR.BUNDLE.ID.YOUR_PROJECT_NAME-Stickers. For example a project named My App with the bundle id com.mycompany.myapp should have a sticker pack folder My App Stickers and will receive the bundle id com.mycompany.myapp.My-App-Stickers.
