Type strict builder class for NSAttributedString.

What’s this?

StringStylizer makes NSAttributedString more intuitive with Method chain and Operator.
Building NSAttributedString is so difficult because it requires us to remember attribute names and types. If you do that with StringStylizer, There is no need to remember them :smiley:

NSAttributedString has the following format.

let attr: [String: AnyObject] = [
    NSForegroundColorAttributeName: UIColor.whiteColor(),
    NSFontAttributeName: UIFont(name: "HelveticaNeue", size: 14)
]
let str = NSAttributedString(string: "some text", attributes: attr)

StringStylizer enable developers to read and write their code in a linear manner.
If you wanna convert String to NSAttributedString which has some colors, sizes and fonts, you can write that as follows.

let str = "some text".stylize().color(.whiteColor()).size(14).font(.HelveticaNeue).attr

Feature

  • [x] Type strict format
  • [x] Assigning ranges and attributes in a linear manner
  • [x] More readable than NSAttributedString

Requirements

  • iOS 8.0+
  • Swift 3.0 or Swift 2.3 (swift2.3 branch)

Installation

Carthage

  • Install Carthage from Homebrew
    > ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
    > brew update
    > brew install carthage
  • Move your project dir and create Cartfile
    > touch Cartfile
  • add the following line to Cartfile
    github "kazuhiro4949/StringStylizer"
  • Create framework

    > carthage update --platform iOS
  • In Xcode, move to "Genera > Build Phase > Linked Frameworks and Library"
  • Add the framework to your project
  • Add a new run script and put the following code
    /usr/local/bin/carthage copy-frameworks
  • Click "+" at Input file and Add the framework path
    $(SRCROOT)/Carthage/Build/iOS/StringStylizer.framework
  • Write Import statement on your source file
    Import StringStylizer

CocoaPods

  • Install CocoaPods
    > gem install cocoapods
    > pod setup
  • Create Podfile
    > pod init
  • Edit Podfile
    
    # Uncomment this line to define a global platform for your project
    platform :ios, '8.0'  # add
    use_framework!  # add

target ‘MyAppName’ do
pod ‘StringStylizer’ # add
end

target ‘MyAppTests’ do

end

target ‘MyAppUITests’


+ Install

pod install


open .xcworkspace

Example

 let label = UILabel(frame: CGRectMake(0, 0, 100, 50))

 // build NSAttributedString.
 let greed = "Hi, ".stylize().color(0x2200ee).size(12).font(.HelveticaNeue).attr

 // build NSAttributedString with ranges.
 let msg = "something happened ".stylize()
                .range(0..<9)        .color(0x009911).size(12).font(.HelveticaNeue)
                .range(10..<UInt.max).color(0xaa22cc).size(14).font(.HelveticaNeue_Bold).attr

 // build NSAttributedString objects and join them.
 let name = "to ".stylize().color(0x23abfc).size(12).font(.HelveticaNeue).attr +
            "you".stylize().color(0x123456).size(14).font(.HelveticaNeue_Italic).underline(.StyleDouble).attr

 label.attributedText = greed + msg + name

This sample generates a styled label.

Of course, you can wrap up the method chains.

extension StringStylizer {
  func strong() -> NSAttributedString {
    return self
            .color(0x123456)
            .size(14)
            .font(.HelveticaNeue_Italic)
            .underline(.StyleDouble)
            .attr
  }
}

label.attributedText = "you".stylize().strong()

Usage

1. Convert String to StringStylizer object

let firstStep = "yay!".stylize() // => StringStylizer<Styling>

2. Call methods to select range. Then, StringStylizer change into "NarrowDown" state

let secondStep = "yay!".stylize().range(0..<UInt.max) // => StringStylizer<NarrowDown>

3. Call methods to set attributes. Then, StringStylizer change into "Styling" state

let thirdStep = "yay!".stylize().range(0..<UInt.max).size(14) // => StringStylizer<Styling>

4. Convert to NSAttributedString object.

let fourthStep = "yay!".stylize().range(0..<UInt.max).size(14).attr // => NSAttributedString

5. Join another NSAttributedString object.

let one     = "yay!".stylize().range(0..<UInt.max).size(14).attr
let another = " yay!".stylize().color(0xffffff).attr
let fifthStep = one + another // => NSAttributedString

That’s it!

Architecture

StringStylizer is based on "Builder Pattern" (Effective Java version). In addition, it has states managed by "Phantom Type".

Because of them, we are able to

  • write our code in a liner manner
  • call proper methods depending on the situation.
