Texstyle allows you to format attributed strings easily.

Features

  • Applying attributes with strong typing and autocompletion
  • Cache for attributes
  • Substyles
  • Convenient extensions for String and UIButton

Requirements

  • iOS 9.0+ / tvOS 9.0+
  • Xcode 10.0+

Usage

Here is a basic example of Texstyle using:

let text = Text(value: "Hello, World ?", style: .title1)
text.add(.heading1, for: "World")
titleLabel.attributedText = text.attributed

The result:

Example1

Let's start with text styles. There is a TextStyle class for configuring different style parameters like font, color, kerning etc. We prefer to use TextStyle extension for app specific styles:

extension TextStyle {

    static let title1: TextStyle = {
        let style = TextStyle()
        style.font = .systemFont(ofSize: 32, weight: .regular)
        return style
    }()
        
    static let heading1: TextStyle = {
        let style = TextStyle()
        style.font = .systemFont(ofSize: 28, weight: .semibold)
        style.color = .purple
        return style
    }()
}

It allows you to reuse the styles across the app.

Next, create a Text instance. It contains string value and style:

let text = Text(value: "Hello, World ?", style: .title1)

Text also supports independent styles for each UIControl.State. For example, if you want to use a different style for button highlight state, you should initialize text like:

let text = Text(value: " Sign in with Apple", styles: [.normal: .heading1,
                                                         .highlighted: .heading2])

To create an attributed string, just use:

//By default for normal state
text.attributed

//For needed state
text.attributed(for: .highlighted)

All attributed strings are cached by default. It's useful in reusable elements like UICollectionViewCell or UITableViewCell.

There are custom operators for texts and strings:

let text1 = Text(value: "Ros", style: .title1)
let text2 = text1 + "ber"
let text3 = Text(value: "ry", style: .title1)
let text4 = text2 + text3
text4.value // "Rosberry"

There are convenience APIs for text creation and applying:

//String to text
"Settings".text(with: .heading1)

//UIButton
button.setText(text)

Cache

TextStyle and Text classes have internal cache to prevent extra calculation. TextStyle caches attributes and invalidates it on any attribute change. Text has cached attributed strings for states. For example, if you use texts in collection view cells and want to update some labels in it after reuse, texts return cached strings. Please note that texts won't invalidate cached strings if you update textstyle attributes.
