base on Markdown View for iOS. # MarkdownView [](https://travis-ci.org/keitaoouchi/MarkdownView) [](https://swift.org/) [](https://github.com/Carthage/Carthage) [](http://cocoapods.org/pods/MarkdownView) [](http://cocoapods.org/pods/MarkdownView) [](https://github.com/apple/swift-package-manager) > MarkdownView is a WKWebView based UI element, and internally use markdown-it, highlight-js.  ## How to use #### UIViewController ```swift import MarkdownView let md = MarkdownView() md.load(markdown: "# Hello World!") ``` #### SwiftUI ```swift import SwiftUI import MarkdownView struct SampleUI: View { var body: some View { ScrollView { MarkdownUI(body: markdown) .onTouchLink { link in print(link) return false } .onRendered { height in print(height) } } } private var markdown: String { let path = Bundle.main.path(forResource: "sample", ofType: "md")! let url = URL(fileURLWithPath: path) return try! String(contentsOf: url, encoding: String.Encoding.utf8) } } ``` ### Options ```swift md.isScrollEnabled = false // called when rendering finished md.onRendered = { [weak self] height in self?.mdViewHeight.constant = height self?.view.setNeedsLayout() } // called when user touch link md.onTouchLink = { [weak self] request in guard let url = request.url else { return false } if url.scheme == "file" { return false } else if url.scheme == "https" { let safari = SFSafariViewController(url: url) self?.navigationController?.pushViewController(safari, animated: true) return false } else { return false } } ``` ### Experimental Features This is not stable :bow: #### Custom CSS Styling Please check [Example/ViewController/CustomCss.swift](https://github.com/keitaoouchi/MarkdownView/blob/master/Example/Example/ViewController/CustomCss.swift). <img src="https://github.com/keitaoouchi/MarkdownView/blob/master/sample_css.png" width=300> #### Plugins Please check [Example/ViewController/Plugins.swift](https://github.com/keitaoouchi/MarkdownView/blob/master/Example/Example/ViewController/Plugins.swift).
