Installation

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods

To integrate iMessageDataKit into your Xcode project using CocoaPods, specify it in your Podfile:

pod 'iMessageDataKit'

Then, run the following command in Terminal (from your project's root folder):

$ pod install

Manual

Drag & drop Source folder into your Xcode project.

Usage

iMessageDataKit extension methods enable you to use an MSMessage object as a dictionary-like key-value store. You can set/get Int, Bool, Float, Double, String and Array values. Arrays should contain objects that conform to LosslessStringConvertible protocol.

Quick Start

import Messages
import iMessageDataKit

class MessagesViewController: MSMessagesAppViewController {

  // ...

  func sendMessage() {

    let layout = MSMessageTemplateLayout()
    layout.caption = "A message with custom data."

    let message: MSMessage = MSMessage()
    message.layout = layout

    //
    // set custom data
    //
    message.md.set(value: 7, forKey: "user_id")
    message.md.set(value: Int(NSDate().timeIntervalSince1970), forKey: "timestamp")
    message.md.set(value: true, forKey: "is_okay")
    message.md.set(value: "john", forKey: "username")
    message.md.set(values: ["happy", "joy", "smile"], forKey: "tags")
    message.md.set(values: [7.3, 5.2], forKey: "dimensions")

    //
    // send or insert message to activeConversation ...
    //
  }

  override func didSelect(_ message: MSMessage, conversation: MSConversation) {

    //
    // access selected message's custom data
    //

    if let userId = message.md.integer(forKey: "user_id") {
      // do sth with userId
    }

    if let timestamp = message.md.integer(forKey: "timestamp") {
      // do sth with timestamp
    }

    if let isOkay = message.md.bool(forKey: "is_okay") {
      // do sth with isOkay
    }

    if let username = message.md.string(forKey: "username") {
      // do sth with username
    }

    if let tags = message.md.values(forKey: "tags") {
      // do sth with tags array
    }

    if let dimensions = message.md.values(forKey: "dimensions") {
      // do sth with dimensions array
    }
  }

  // ...

}

How it works

iMessageDataKit encodes/decodes data as JSON and utilizes url property of MSMessage class to store encoded JSON string as a querystring.
