Installation

Installation via CocoaPods

MarkdownKit is available through CocoaPods. CocoaPods is a dependency manager that automates and simplifies the process of using 3rd-party libraries like MarkdownKit in your projects. You can install CocoaPods with the following command:

gem install cocoapods

To integrate MarkdownKit into your Xcode project using CocoaPods, simply add the following line to your Podfile:

pod "MarkdownKit"

Afterwards, run the following command:

pod install

Installation via Carthage

MarkdownKit is available through Carthage. Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage via Homebrew with the following command:

brew update
brew install carthage

To integrate MarkdownKit into your Xcode project using Carthage, simply add the following line to your Cartfile:

github "ivanbruel/MarkdownKit"

Usage

In order to use MarkdownKit to transform Markdown into NSAttributedString, all you have to do is create an instance of MarkdownParser and call the parse(_) function.

let markdownParser = MarkdownParser()
let markdown = "I support a *lot* of custom Markdown **Elements**, even `code`!"
label.attributedText = markdownParser.parse(markdown)

Customization

let markdownParser = MarkdownParser(font: UIFont.systemFontOfSize(18))
markdownParser.enabledElements = .disabledAutomaticLink
markdownParser.bold.color = UIColor.redColor()
markdownParser.italic.font = UIFont.italicSystemFontOfSize(300)
markdownParser.header.fontIncrease = 4

Extensibility

To add new Markdown elements all you have to do is implement the MarkdownElement protocol (or descendants) and add it to the MarkdownParser.

import MarkdownKit

class MarkdownSubreddit: MarkdownLink {

  private static let regex = "(^|\\s|\\W)(/?r/(\\w+)/?)"

  override var regex: String {
    return MarkdownSubreddit.regex
  }

  override func match(match: NSTextCheckingResult,
                             attributedString: NSMutableAttributedString) {
    let subredditName = attributedString.attributedSubstringFromRange(match.rangeAtIndex(3)).string
    let linkURLString = "http://reddit.com/r/\(subredditName)"
    formatText(attributedString, range: match.range, link: linkURLString)
    addAttributes(attributedString, range: match.range, link: linkURLString)
  }

}
let markdownParser = MarkdownParser(customElements: [MarkdownSubreddit()])
let markdown = "**/r/iosprogramming** can be *markdown* as well!"
label.attributedText = markdownParser.parse(markdown)

Example

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