Example

To run the example project, clone the repo, and run pod install from the Example directory first.

Requirements

  • iOS 9.0+
  • Swift 4.2

Installation

AttributedStringStyle is available through CocoaPods. To install
it, simply add the following line to your Podfile:

pod 'AttributedStringStyle'

How to use it

Define some abstract style anywhere in your app. For instance.

enum Style {
    case regular
    case highlighted
}

Once your style is defined we have two tools at your disposal:

  • AttributedStringBuilder that is helpful to create attributed string with styles for range of characters
  • AttributedStringStyler that defines which visual attributes to apply for each style

To create your attributed string and focus on the semantic and not the display, use the builder like so:

let content = "A simple string"
let builder = AttributedStringBuilder<Style>(string: content)
builder.setStyle(.regular)
let range = NSString(string: content).range(of: "simple")
builder.addStyle(.highlighted, range: range)
let semanticAttributedString = builder.build()

The attributed string has no visual attributes but semantics ones.

Simple String Semantics

Once your semantic content is defined, you can use the styler to create a new attributed string with visual attributes.

let styler = AttributedStringStyler<Style>()
styler.register(
    attributes: [
        .font: UIFont.systemFont(ofSize: 14),
        .foregroundColor: UIColor.gray
    ],
    forStyle: .regular
)
styler.register(
    attributes: [
        .font: UIFont.boldSystemFont(ofSize: 14),
        .foregroundColor: UIColor.black
    ],
    forStyle: .highlighted
)

let visualAttributedString = semanticAttributedString.styled(with: styler)

This time the result is visual.
