UIStrokeAnimatedLabel (Swift)

A UILabel subclass with stroke drawing animations, with customization options

A UIStrokeAnimatedLabel is a UILabel that has a stroke animation when displayed. Animation duration, stroke width and spacing and easily customizable through Interface Builder or programatically.

Installation

Build and link the UIStrokeAnimatedLabel framework (UIStrokeAnimatedLabel/UIStrokeAnimatedLabelFramework.xcodeproj).

Alternatively, copy UIStrokeAnimatedLabel/UIStrokeAnimatedLabel/UIStrokeAnimatedLabel.swift directly in your project.

Usage and customization

A UIStrokeAnimatedLabel can be created and customized through Interface Builder or programmatically.

Interface Builder

1. Drag a UILabel into a view.
2. Set the label's class to UIStrokeAnimatedLabel. You might also need to set the Module name to UIStrokeAnimatedLabelFramework if using CocoaPods.

Customize the label using the Attributes inspector. From there, animation duration and stroke color can be modified.

Programmatically

Create IBOutlets or create the labels programatically.

@IBOutlet weak var swiftLabel: UIStrokeAnimatedLabel!
@IBOutlet weak var rocksLabel: UIStrokeAnimatedLabel!

override func viewDidLoad() {
  super.viewDidLoad()

    swiftLabel.animationDuration = 1.0
    rocksLabel.animationDuration = 2.0

    swiftLabel.strokeWidth = .relative(scale: 1.4)
    rocksLabel.strokeColor = .gray
    swiftLabel.characterSpacing = .absolute(value: 20.0)
    rocksLabel.wordSpacing = .relative(scale: 0.5)

    rocksLabel.animationEnabled = true
    
    rocksLabel.completionHandler = {
      print("Animation complete")
    }
}
