A SlackTextViewController replacement written in Swift for the iPhone X.

Last update: Jan 4, 2023

Overview

Installation

Just add MessageViewController to your Podfile and install. Done!

pod 'MessageViewController'

Setup

You must subclass MessageViewController.

import MessageViewController

class ViewController: MessageViewController {
  // ...
}

Finish setup using a UIScrollView. Remember this can also be a UITableView or UICollectionView.

func viewDidLoad() {
  super.viewDidLoad()
  setup(scrollView: scrollView)
}

Customizations

You can customize any part of the UI that you want!

// Border between the text view and the scroll view
borderColor = .lightGray

// Change the appearance of the text view and its content
messageView.inset = UIEdgeInsets(top: 8, left: 16, bottom: 8, right: 16)
messageView.textView.placeholderText = "New message..."
messageView.textView.placeholderTextColor = .lightGray
messageView.font = .systemFont(ofSize: 17)

// Setup the button using text or an icon
messageView.set(buttonTitle: "Send", for: .normal)
messageView.addButton(target: self, action: #selector(onButton))
messageView.buttonTint = .blue

// Set custom attributes for an autocompleted string
let tintColor = .blue
messageAutocompleteController.autocompleteTextAttributes = ["@": [.font: UIFont.preferredFont(forTextStyle: .body), .foregroundColor: tintColor, .backgroundColor: tintColor.withAlphaComponent(0.1)]]

Autocomplete

The base view controller uses a MessageAutocompleteController control to handle text autocompletion.

This control uses a plain UITableView to display its autocomplete. Add a dataSource and delegate to display and handle interactions.

let tableView = messageAutocompleteController.tableView
tableView.register(UITableViewCell.self, forCellReuseIdentifier: "cell")
tableView.dataSource = self
tableView.delegate = self

Then register for autocomplete prefixes you want to respond to and set a delegate to handle when a prefix is found.

messageAutocompleteController.register(prefix: "@")
messageAutocompleteController.delegate = self

Your delegate needs to implement just one method.

func didFind(controller: MessageAutocompleteController, prefix: String, word: String) {
  // filter your data
  controller.show(true)
}

Note: You can perform asyncronous autocomplete searches. Just be sure to call messageAutocompleteController.show() when finished.

Inconsistent text view font

The latest release, 0.2.0, is causing the font to change in the text view as I type. Also introducing the left button has caused some really strange layout issues. For example, if I set showsLeftButton to false, the insets are rendered completely off center.

Autocomplete feature only

Hi Ryan,

Love the functionality of the autocomplete! I'm looking for a way to apply the autocomplete feature to a UITextView without all the other goodies.

Example, add a UITextView to a storyboard ViewController and apply the autocomplete feature alone, by adding a custom class to the UITextView or however you suggest. Do you have any examples of this or point me in the right direction?

Thanks for the help!

How to integrate MessageViewController with MessageKit or JSQMessageViewController

This library is really nice, but I'm wondering how to integrate it with others libraries to create a chat

MessageKit has it's own Controller to inherit and MessageViewController too, what is the best pratique to mix theses libraries ?

I've try to make a parent controller with MessageViewController and use JSQMessageViewController as a child (I know this library is deprecated)

I've try to make the configuration of MessageViewController in both viewdidload but it crash because of UI constraint

Thank you so much for your help

messageView.font seems to not be working?

I keep trying to set the font on my messageView just like in the examples

messageView.font = .systemFont(ofSize: 15) or messageView.font = .systemFont(ofSize: 20) or whatever

and it always seems to start going back to [I think] size 17 font.

Screenshot below shows size 20 font for the first word then for some reason gets smaller and stays like that.

Realize I'm using a custom keyboard: Tried it with both default iOS keyboard and Gboard.

Input customization point

Originated from #53.

As far as I can see there is no trivial way to do this, so I went the easiest way and forced developers implementing listeners to be cautious and do be aware about might-be-clashing manipulations of text and/or attributes.

7e39198 tinily improved removing of autocompleted text leaving preceding character (which is probably a space AFAIK). (e.g "Hello @SD10" becomes "Hello " instead of "Hello")

SwiftLint

Integrates SwiftLint to lint all the swifts! Closes #16

Questions:

Anything else you might want in the .swiftlint.yml?
I've added SwiftLint Run Script Build Phases, do you want those?
I've used swiftlint --strict, that work? Or do you prefer it without --strict

Code Changes (not just whitespace):

class ViewController: MessageViewController, UITableViewDataSource, UITableViewDelegate, MessageAutocompleteControllerDelegate was violating the line_length rule, so I switched it to class ViewController: MessageViewController ... extension ViewController: UITableViewDataSource, etc.. You may prefer a revert, and just disabling that rule there
Switching to block-based key-value observing as per SwiftLint rule

Add @mention highlighting support to autocomplete

Hey!

First off thanks for the GitHawk app, I use it all the time! I liked your implementation of autocomplete, as I to did something similar for an InputAccessoryView that made its way into MessageKit.

I notice that in the GitHawk app @mention is highlighted with colors but not in the UITextView for the MessageViewController. Is this something you are already working towards? If not I would be happy to make a PR to support this feature! 😊

How to change textColor or TextView. Scroll issue when started typing.
I have integrated MessageViewController for Chat in my application. I am facing 2 issues right now:

I am not able to change textcolor of the textview. I have dark and normal mode and I need to change the textColor based on mode I select.

When I start typing into the textview, the tableview in which I am currently displaying the chat messages, scrolls up a little.

Please reply me ASAP as we need to go in production and I have already move here from SlackTextViewController.
