SwiftyAttributes

A Swifty API for attributed strings.

Swift Version Swift Version Carthage compatible CocoaPods Compatible Platform Travis CI codecov.io


With SwiftyAttributes, you can create attributed strings like so:

let fancyString = "Hello World!".withTextColor(.blue).withUnderlineStyle(.styleSingle)

Alternatively, use the Attribute enum:

let fancyString = "Hello World!".withAttributes([
    .backgroundColor(.magenta),
    .strokeColor(.orange),
    .strokeWidth(1),
    .baselineOffset(5.2)
])

You can also easily combine attributed strings using a plus sign:

let fancyString = "Hello".withFont(.systemFont(ofSize: 12)) + " World!".withFont(.systemFont(ofSize: 18))

SwiftyAttributes has support for every attribute available in Cocoa and Cocoa Touch.

Requirements

  • iOS 8.0+, macOS 10.11+, watchOS 2.0+, tvOS 9.0+
  • Swift 4 or 3
  • Xcode 9 or 10

Installation

With CocoaPods

pod 'SwiftyAttributes'

With Carthage

github "eddiekaiger/SwiftyAttributes"

Usage

Initializing attributed strings in SwiftyAttributes can be done several ways:

  • Using the with[Attribute] extensions:

    "Hello World".withUnderlineColor(.red).withUnderlineStyle(.styleDouble)
  • Using the Attribute enum extensions:

    "Hello World".withAttributes([.underlineColor(.red), .underlineStyle(.styleDouble)])
  • Using the Attribute enum in an initializer:

    NSAttributedString(string: "Hello World", swiftyAttributes: [.kern(5), .backgroundColor(.gray)])

You can retrieve the attribute at a specific location using an attribute name from the Attribute.Name enum:

let attr: Attribute? = myAttributedString.swiftyAttribute(.shadow, at: 5)

Several API methods are provided to use these new enums as well as Swift's Range type instead of NSRange. Some of the method signatures include:

extension NSMutableAttributedString {
    func addAttributes(_ attributes: [Attribute], range: Range<Int>)
    func addAttributes(_ attributes: [Attribute], range: NSRange)
    func setAttributes(_ attributes: [Attribute], range: Range<Int>)
    func setAttributes(_ attributes: [Attribute], range: NSRange)
    func replaceCharacters(in range: Range<Int>, with str: String)
    func replaceCharacters(in range: Range<Int>, with attrString: NSAttributedString)
    func deleteCharacters(in range: Range<Int>)
    func removeAttribute(_ name: NSAttributedStringKey, range: Range<Int>)
}

extension NSAttributedString {
    convenience init(string str: String, swiftyAttributes: [Attribute])
    func withAttributes(_ attributes: [Attribute]) -> NSMutableAttributedString
    func withAttribute(_ attribute: Attribute) -> NSMutableAttributedString
    func attributedSubstring(from range: Range<Int>) -> NSAttributedString
    func swiftyAttribute(_ attrName: NSAttributedStringKey, at location: Int, effectiveRange range: NSRangePointer? = nil) -> Attribute?
    func swiftyAttributes(in range: Range<Int>, options: NSAttributedString.EnumerationOptions = []) -> [([Attribute], Range<Int>)]
    func enumerateSwiftyAttributes(in enumerationRange: Range<Int>, options: NSAttributedString.EnumerationOptions = [], using block: (_ attrs: [Attribute], _ range: Range<Int>, _ stop: UnsafeMutablePointer<ObjCBool>) -> Void)
    func enumerateSwiftyAttribute(_ attrName: NSAttributedStringKey, in enumerationRange: Range<Int>, options: NSAttributedString.EnumerationOptions = [], using block: (_ value: Any?, _ range: Range<Int>, _ stop: UnsafeMutablePointer<ObjCBool>) -> Void)
}

extension String {
    var attributedString: NSMutableAttributedString
    func withAttributes(_ attributes: [Attribute]) -> NSMutableAttributedString
    func withAttribute(_ attribute: Attribute) -> NSMutableAttributedString
}

// ... and more!
