TelegraphKit

TelegraphKit allows you to show web-content from telegra.ph in a way that looks & feels native on an iOS device.

“Wait, what on Earth is telegra.ph?”

Telegraph is “a publishing tool that lets you create richly formatted posts with photos and all sorts of embedded stuff”. It’s main advantage is that you can create posts in seconds, with no need for an account and no configuration. And then using TelegraphKit you can easily show these posts in your app.

Huge thanks to @danielpunkass for his post “Supporting Dark Mode: In-App Web Content”, it helped us tremendously!

Usage

1. Create a post on telegra.ph. There is no need to create an account or configure anything. Tap “PUBLISH” and copy the link.

2. Add TelegraphKit to your project (see “Installation” section below)

3. Somewhere in your project:

import TelegraphKit

let url = URL(string: "<your-telegraph-url>")!
let telegraphVC = TelegraphViewController(url: url)
let nvc = UINavigationController(rootViewController: telegraphVC)
self.present(nvc, animated: true)

Guide

TelegraphKit is built on top of WKWebView that adds a few extra features specifically for telegra.ph articles:

• Dark Mode support (Telegraph web-version only supports light mode)
• Native fonts: TelegraphKit substitutes Telegra.ph fonts for Apple system ones in order to achieve that “native look and feel” (this can be configured)
• Customization: select between system and telegra.ph font styles, hide the author & date section, disable text selection & more.
• Layout improvements: TelegraphKit makes slight adjustments to the layout of the page to make it look best inside iOS apps

Creating TelegraphViewController

let telegraphVC = TelegraphViewController(url: URL(string: "https://telegra.ph/This-is-TelegraphKit-02-03")!)
// or
let telegraphVC = TelegraphViewController(postID: "This-is-TelegraphKit-02-03")

Customizing the appearance

You can configure the appearance of your TelegraphViewController by using TelegraphViewController.Appearance struct:

let telegraphVC = TelegraphViewController(postID: "<your-post-id>", appearance: .appleSystem)

TelegraphKit provides you with two presets:

TelegraphViewController.Appearance
--->.appleSystem // (default)
--->.telegraph

--->.defaultAppearance // (equals .appleSystem by default)

You can fine-tune the appearance by creating it directly:

TelegraphViewController.Appearance(
    fontStyle: TelegraphViewController.Appearance.FontStyle, // .appleSystem or .telegraph
    hideAuthor: Bool,
    darkModeSupport: Bool, // true by default
    disableImageInteraction: Bool, // true by default
    disableSelection: Bool // false by default
)

To change the default appearance globally, you can modify TelegraphViewController.Appearance.defaultAppearance:

// Somewhere in AppDelegate.swift or similar:
TelegraphViewController.Appearance.defaultAppearance = .telegraph
