Easiest way to create an attributed UITextView (with support for multiple links and html).

See the demo app and the playground for detailed information how to use AttributedTextView


  • iOS 8.0+
  • Xcode 8.0+


General usage

In interfacebuilder put an UITextView on the canvas and set the base class to AttributedTextView and create a referencing outlet to the a property in your viewController. In the samples below we have called this property textView1. Always assign to the attributer property when you want to set something.

Paragraph styling

You do have to be aware that the paragraph functions will only be applied after calling the .paragraphApplyStyling function. On start the paragraph styling will use default styling. After each range change (what happens after .all, .match* or .append) the styling will be reset to the default.

The active range

Styling will always be applied on the active range. When executing a function on a string, then that complete string will become the active range. If you use .append to add an other string, then that latest string will become the active range. When using the + sign then that will replaced by an append on 2 Attributer objects. All functions on those objects will first be performed before the append will be executed. So if you do an .all then still only one of the strings will be tha active range. You can use brackets to influence the order of execution.

For instance here all text will be size 20

("red".red + "blue".blue).all.size(20)

And here only the text blue will be size 20

"red".red + "blue".blue.all.size(20)

And like this all text will be size 20


When using AttributedTextView and creating links with .makeInteract, then you have to be aware that it will also automatically set the following properties which are needed for links to work.

isUserInteractionEnabled = true
isSelectable = true
isEditable = false

Sample code

Here is a sample of some basic functions:

textView1.attributer =
    "1. ".red
    .append("This is the first test. ").green
    .append("Click on ").black
    .append("").makeInteract { _ in "")!, options: [:], completionHandler: { completed in })
    .append(" for testing links. ").black
    .append("Next test").underline.makeInteract { _ in
    .all.font(UIFont(name: "SourceSansPro-Regular", size: 16))


Some more attributes and now using + instead of .append:

textView1.attributer =
    "2. red, ".red.underline.underline(0x00ff00)
    + "green, ".green.fontName("Helvetica").size(30)
    + "cyan, ".cyan.size(22)
    + "orange, ".orange.kern(10)
    + "blue, ".blue.strikethrough(3).baselineOffset(8)
    + "black.".shadow(color: UIColor.gray, offset: CGSize(width: 2, height: 3), blurRadius: 3.0)


A match and matchAll sample:

textView1.attributer = "It is this or it is that where the word is is selected".size(20)


A hashtags and mentions sample:

textView1.attributer = "@test: What #hashtags do we have in @evermeer #AtributedTextView library"
    .makeInteract { link in "\(link.replacingOccurrences(of: "@", with: ""))")!, options: [:], completionHandler: { completed in })


A html sample:

textView1.attributer = "My name is: <b>Edwin</b><br/>With a bulet list<br/><ul><li>item 1</li><li>item 2</li></ul>".html


Some other text formating samples:

textView1.attributer =  (
    "test stroke".strokeWidth(2).strokeColor(
    + "test stroke 2\n".strokeWidth(2).strokeColor(
    + "test strikethrough".strikethrough(2).strikethroughColor(
    + " test strikethrough 2\n".strikethrough(2).strikethroughColor(UIColor.yellow)
    + "letterpress ".letterpress
    + " obliquenes\n".obliqueness(0.4).backgroundColor(UIColor.cyan)
    + "expansion\n".expansion(0.8)


Paragraph formatting:

textView1.attributer = (
    "The quick brown fox jumps over the lazy dog.\nPack my box with five dozen liquor jugs.\nSeveral fabulous dixieland jazz groups played with quick tempo."

Use the attributedText functionality on a UILabel

You can also use the Attributer for your UILabel. You only can't use the makeInteract function:

let myUILabel = UILabel()
myUILabel.attributedText = ("Just ".red + "some ".green + "text.".orange).attributedText

Extending AttributedTextView

In the demo app you can see how you can extend the AttributedTextView with a custom property / function that will perform multiple actions. Here is a simple sample that will show you how you can create a myTitle property that will set multiple attributes:

extension Attributer {
    open var myTitle: Attributer {
        get {
            return self.fontName("Arial").size(28).color(0xffaa66).kern(5)

public extension String {
    var myTitle: Attributer {
        get {
            return attributer.myTitle

Decorating the Attributed object

In the demo app there is also a sample that shows you how you could decorate an Attributed object with default styling.

        attributedTextView.attributer = decorate(4) { content in return content
            + "This is our custom title".myTitle

The decorate function can then look something like this:

    func decorate(_ id: Int, _ builder: ((_ content: Attributer) -> Attributer)) -> Attributer {
        var b = "Sample \(id + 1):\n\n".red
        b = builder(b) // Now add the content
        return b

Creating your own custom label

There is also an AttributedLabel class which derives from UILabel which makes it easy to create your own custom control that includes support for interfacebuilder. If you put a lable on a form in interfacebuilder and set it's class to your subclass (AttributedLabelSubclassDemo in the sample below) Then you will see the text formated in interface building according to what you have implemented in the configureAttributedLabel function. Here is a sample where a highlightText property is added so that a text can be constructed where that part is highlighted.

import AttributedTextView
import UIKit

@IBDesignable open class AttributedLabelSubclassDemo: AttributedLabel {

    // Add this field in interfacebuilder and make sure the interface is updated after changes
    @IBInspectable var highlightText: String? {
        didSet { configureAttributedLabel() }

    // Configure our custom styling.
    override open func configureAttributedLabel() {
        self.numberOfLines = 0
        if let highlightText = self.highlightText {
            self.attributedText = self.text?.green.match(highlightText).red.attributedText
        } else {
            self.attributedText = self.text?.green.attributedText

In the demo app there is also a lable subclass for an icon list like this:

You can find the code here:
Icon bulet list code

Creating your own custom textview

You could do the same as a label with the AttributedTextView (see previous paragraph). In the sample below 2 properties are entered into interfacebuilder the linkText is the part of the text what will be clickable and linkUrl will be the webpage that will be opened.

import AttributedTextView
import UIKit

@IBDesignable class AttributedTextViewSubclassDemo: AttributedTextView {

    // Add this field in interfacebuilder and make sure the interface is updated after changes
    @IBInspectable var linkText: String? {
        didSet { configureAttributedTextView() }

    // Add this field in interfacebuilder and make sure the interface is updated after changes
    @IBInspectable var linkUrl: String? {
        didSet { configureAttributedTextView() }

    // Configure our custom styling.
    override func configureAttributedTextView() {
        if let text = self.text, let linkText = self.linkText, let linkUrl = self.linkUrl {
            self.attributer = { _ in
       linkUrl)!, options: [:], completionHandler: { completed in })
        } else {
            self.attributer = (self.text ?? "").green



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

$ gem install cocoapods

CocoaPods 1.1.0+ is required to build AttributedTextView 0.1.0+.

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

source ''
platform :ios, '8.0'

pod 'AttributedTextView', '~> 0.5.1'

Then, run the following command:

$ pod install


Carthage is a decentralized dependency manager that automates the process of adding frameworks to your Cocoa application.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate AttributedTextView into your Xcode project using Carthage, specify it in your Cartfile:

github "evermeer/AttributedTextView" ~> 0.5.1

Swift Package Manager

To use AttributedTextView as a Swift Package Manager package just add the following in your Package.swift file.

import PackageDescription

let package = Package(
name: "HelloAttributedTextView",
dependencies: [
.Package(url: "", "0.5.1")


If you prefer not to use either of the aforementioned dependency managers, you can integrate AttributedTextView into your project manually.

Git Submodules

  • Open up Terminal, cd into your top-level project directory, and run the following command "if" your project is not initialized as a git repository:
$ git init
  • Add AttributedTextView as a git submodule by running the following command:
$ git submodule add
$ git submodule update --init --recursive
  • Open the new AttributedTextView folder, and drag the AttributedTextView.xcodeproj into the Project Navigator of your application's Xcode project.

It should appear nested underneath your application's blue project icon. Whether it is above or below all the other Xcode groups does not matter.

  • Select the AttributedTextView.xcodeproj in the Project Navigator and verify the deployment target matches that of your application target.
  • Next, select your application project in the Project Navigator (blue project icon) to navigate to the target configuration window and select the application target under the "Targets" heading in the sidebar.
  • In the tab bar at the top of that window, open the "General" panel.
  • Click on the + button under the "Embedded Binaries" section.
  • You will see two different AttributedTextView.xcodeproj folders each with two different versions of the AttributedTextView.framework nested inside a Products folder.

It does not matter which Products folder you choose from.

  • Select the AttributedTextView.framework.

  • And that's it!

The AttributedTextView.framework is automagically added as a target dependency, linked framework and embedded framework in a copy files build phase which is all you need to build on the simulator and a device.

Embeded Binaries

  • Download the latest release from
  • Next, select your application project in the Project Navigator (blue project icon) to navigate to the target configuration window and select the application target under the "Targets" heading in the sidebar.
  • In the tab bar at the top of that window, open the "General" panel.
  • Click on the + button under the "Embedded Binaries" section.
  • Add the downloaded AttributedTextView.framework.
  • And that's it!
