It provides convenient way to store styles you can reuse in your app's UI elements, allows complex tag-based strings rendering and also includes integration with Interface Builder. It even support **iOS 11's Dynamic Type**! If you manipulate `NSAttributedString` in Swift, SwiftRichString allows you to keep your code manteniable, readable and easy to evolve. ## Features Highlights Want to know what SwiftRichString can do in your app? Lets take a look to these feature highlights! ### 1. Easy Styling The main concept behind this lib is the `Style`: a style is just a collection of text attributes you can apply to a string. The following example show how to create a style an produce an attributed string with it: ```swift let style = Style { $0.font = SystemFonts.AmericanTypewriter.font(size: 25) // just pass a string, one of the SystemFonts or an UIFont $0.color = "#0433FF" // you can use UIColor or HEX string! $0.underline = (.patternDot, UIColor.red) $0.alignment = .center } let attributedText = "Hello World!".set(style: style) // et voilà! ``` ### 2. Global Styles & Interface Builder Integration Styles can be also registered globally and reused in your app. Just define your own style and register using `Styles.register()` function: ```swift let myStyle = Style { // define style's attributes... } Styles.register("MyStyle", style: style) ``` Now you can reuse it everything in your app; SwiftRichString exposes a `styleName` property for the most common text containers and you can set it directly in Interface Builder: ### 3. Complex Rendering with tag-based strings SwiftRichString allows you to render complex strings by parsing text's tags: each style will be identified by an unique name (used inside the tag) and you can create a `StyleGroup` which allows you to encapsulate all of them and reuse as you need (clearly you can register it globally). ```swift // Create your own styles let normal = Style { $0.font = SystemFonts.Helvetica_Light.font(size: 15) } let bold = Style { $0.font = SystemFonts.Helvetica_Bold.font(size: 20) $0.color = UIColor.red $0.backColor = UIColor.yellow } let italic = normal.byAdding { $0.traitVariants = .italic } // Create a group which contains your style, each identified by a tag. let myGroup = StyleGroup(base: normal, ["bold": bold, "italic": italic]) // Use tags in your plain string let str = "Hello <bold>Daniele!</bold>. You're ready to <italic>play with us!</italic>" self.label?.attributedText = str.set(style: myGroup) ``` That's the result! -- ## Documentation **Are you using SwiftRichString 1.x in your project? Don't miss to take a look at [Migration section of the documentation](#migration).** You can still use the 1.x release by using tagged version 1.1.0. **Table Of Contents** Full changelog is available in [CHANGELOG.md](CHANGELOG.md) file. - [Versions (1.x, 2.x and old Swift 3.x branch)](#versions) - [Introduction to `Style`, `StyleGroup` & `StyleRegEx`](#stylestylegroup) - [Introduction](#introduction) - [String & Attributed String concatenation](#concatenation) - [Apply styles to `String` & `Attributed String`](#manualstyling) - [Fonts & Colors in `Style`](#fontscolors) - [Derivating a `Style`](#derivatingstyle) - [Support iOS's `Dynamic Type`](#dynamictype) - [Dynamic Attributes from Tag's Params](#dynamicattributes) - [The `StyleManager`](#stylemanager) - [Register globally available styles](#globalregister) - [Defer style creation on demand](#defer) - [Assign style using Interface Builder](#ib) - [All properties of `Style`](#props) Other info: - [Migration from SwiftRichString 1.x](#migration) - [Requirements](#requirements) - [Installation](#installation) - [Contributing](#contributing) - [Copyright](#copyright) <a name="versions"/ rel='nofollow' onclick='return false;'> ### Versions - **SwiftRichString 2.x branch (current)**. The latest version is [2.0.2](https://github.com/malcommac/SwiftRichString/releases/tag/2.0.2). - **SwiftRichString 1.x branch (supported)**. Use [1.1.0 tag](https://github.com/malcommac/SwiftRichString/releases/tag/1.1.0). Its compatible with Swift 4.x. - **Swift 3.x (no longer mantained)**. Use [0.9.1 release](https://github.com/malcommac/SwiftRichString/releases/tag/0.9.10). <a name="stylestylegroup"/ rel='nofollow' onclick='return false;'> ## Introduction to `Style`, `StyleGroup`, `StyleRegEx` <a name="introduction"/ rel='nofollow' onclick='return false;'> ### Introduction The main concept behind SwiftRichString is the use of `StyleProtocol` as generic container of the attributes you can apply to both `String` and `NSMutableAttributedString`. Concrete classes derivated by `StyleProtocol` are: `Style`, `StyleGroup` and `StyleRegEx`. Each of these classes can be used as source for styles you can apply to a string, substring or attributed string. #### `Style`: apply style to strings or attributed strings A `Style` is a class which encapsulate all the attributes you can apply to a string. The vast majority of the attributes of both AppKit/UIKit are currently available via type-safe properties by this class. Creating a `Style` instance is pretty simple; using a builder pattern approach the init class require a callback where the self instance is passed and allows you to configure your properties by keeping the code clean and readable: ```swift let style = Style { $0.font = SystemFonts.Helvetica_Bold.font(size: 20) $0.color = UIColor.green // ... set any other attribute } let attrString = "Some text".set(style: style) // attributed string ``` #### `StyleGroup`: Apply styles for tag-based complex string `Style` instances are anonymous; if you want to use a style instance to render a tag-based plain string you need to include it inside a `StyleGroup`. You can consider a `StyleGroup` as a container of `Styles` (but, in fact, thanks to the conformance to a common `StyleProtocol`'s protocol your group may contains other sub-groups too). ```swift let bodyStyle: Style = ... let h1Style: Style = ... let h2Style: Style = ... let group = StyleGroup(base: bodyStyle, ["h1": h1Style, "h2": h2Style]) let attrString = "Some <h1>text</h1>, <h2>welcome here</h2>".set(style: group) ``` The following code defines a group where: - we have defined a base style. Base style is the style applied to the entire string and can be used to provide a base ground of styles you want to apply to the string. - we have defined two other styles named `h1` and `h2`; these styles are applied to the source string when parser encounter some text enclosed by these tags. #### `StyleRegEx`: Apply styles via regular expressions `StyleRegEx` allows you to define a style which is applied when certain regular expression is matched inside the target string/attributed string. ```swift let emailPattern = "([A-Za-z0-9_\\-\\.\\+])+\\@([A-Za-z0-9_\\-\\.])+\\.([A-Za-z]+)" let style = StyleRegEx(pattern: emailPattern) { $0.color = UIColor.red $0.backColor = UIColor.yellow } let attrString = "My email is hello@danielemargutti.com and my website is http://www.danielemargutti.com".(style: style!) ``` The re
