RichEditor

RichEditor is a WYSIWYG editor written in pure Swift. RichEditor is a direct subclass of NSTextView so you'll feel perfectly comfortable using it.

If you are developing a macOS application that uses an NSTextView and you want your users to be able to format their text, you are forced to use the usesInspectorBar property, which adds a formatting toolbar to your NSTextView.

However if you want to modify the UI or modify functionality at all, you'll soon find a dead-end. This is where RichEditor comes in.

Just drag RichEditor into your UI, and you can use RichEditors functionality to easily programatically control which parts of your text are formatted and how. From bolding and underlining to text alignment and text colour, you have control over your text view. You can create your own UI the way you want and connect your UI to the RichEditor functionality.

However if you want to use a template UI, RichEditor has one last trick up its sleeve for you. Simply call the configureToolbar() from your instance of RichEditor and you will have our pre-made toolbar ready to go!

RichEditor also handles the difficult logic of handling text formatting when a user has already highlighted a piece of text, or when you want to export the text with HTML formatting.

RichEditor allows you to control:

• [x] Bolding
• [x] Italics
• [x] Underlining
• [x] Font Selection
• [x] Font Size Selection
• [x] Text Alignment (Left, Centre, Right, Justified)
• [x] Text Colour
• [x] Text Highlight Colour
• [x] Link Insertion
• [x] Bullet Points
• [x] Text Strikethrough
• [x] Attachment Insertion

To do:

• [ ] Implement better bullet point formatting

You can see the provided RichEditorToolbar in action, as well as the export functionality in the screenshots below. These screenshots are taken from the Example project that you can use in the repository in the Example directory.

Usage

RichEditor is a direct subclass of NSTextView and as such, you can drag NSTextView into your storyboard and subclass it there, or you can directly instantiate RichEditor directly in your code using the initialisers from NSTextView.

Exporting

RichEditor allows you to export the content of the RichEditor as a HTML. You can do this as follows.

let html = try richEditor.html()

html() returns an optional String type, and will throw in the event of an error.

Format Types

Below is a walkthrough of formatting that RichEditor allows you to use.

Bold

richEditor.toggleBold()

Italic

richEditor.toggleItalic()

Underline

richEditor.toggleUnderline(.single)

toggleUnderline(_) takes NSUnderlineStyle as an argument, so you can specify which underline style should be applied.

Strikethrough

richEditor.toggleStrikethrough(.single)

toggleStrikethrough(_) takes NSUnderlineStyle as an argument, so you can specify which underline style should be applied with your strikethrough.

Text Colour

richEditor.applyColour(textColour: .green)

applyColour(textColour:) takes NSColor as an argument, so you can specify which colour should be applied.

Text Highlighy Colour

richEditor.applyColour(highlightColour: .green)

applyColour(highlightColour:) takes NSColor as an argument, so you can specify which colour should be applied.

Font

richEditor.apply(font: .systemFont(ofSize: 12))

applyColour(font:) takes NSFont as an argument, so you can specify which font should be applied.

Text Alignment

richEditor.apply(alignment: .left)

applyColour(alignment:) takes NSTextAlignment as an argument, so you can specify which alignment should be applied.

Links

richEditor.insert(link: url, with: name)

insert(link:, with:, at:) takes a URL as an argument, so you can specify which alignment should be applied.

A String is also taken for how you want this link to appear to the user.

An optional Int argument can also be supplied which indicates what index of the NSTextViews string the link should be insert at. If nil, the link will be appended to the end of the string.

Example Project

To run the example project, clone the repo, and open the example Xcode Project in RichEditorExample.

Requirements

RichEditor supports iOS 10.0 and above & macOS 10.10 and above.

Installation

Swift Package Manager

RichEditor is available through Swift Package Manager. To install it, simply add the dependency to your Package.Swift file:

...
dependencies: [
    .package(url: "https://github.com/will-lumley/RichEditor.git", from: "1.2.0"),
],
targets: [
    .target( name: "YourTarget", dependencies: ["RichEditor"]),
]
...

Cocoapods and Carthage

RichEditor was previously available through CocoaPods and Carthage, however making the library available to all three Cocoapods, Carthage, and SPM (and functional to all three) was becoming troublesome. This, combined with the fact that SPM has seen a serious up-tick in adoption & functionality, has led me to remove support for CocoaPods and Carthage.
