LTMorphingLabel

November 24, 2023

A morphing UILabel subclass written in Swift. The .Scale effect mimicked Apple’s QuickType animation of iOS 8 of WWDC 2014. New morphing effects are available as Swift extensions.

enum LTMorphingEffect: Int, Printable

.Scale – default

.Evaporate

.Fall

.Pixelate

.Sparkle

.Sparkle is built on top of QuartzCore.CAEmitterLayer. There’s also a SpriteKit powered version here.

.Burn

.Anvil

Requirements

Xcode 12
iOS 9.0+

Installation

Swift Package Manager

File > Swift Packages > Add Package Dependency
Copy & paste https://github.com/lexrus/LTMorphingLabel then follow the instruction

XCFramework

XCFramework is a new option introduced in Xcode 11. You can manually download the pre-compiled LTMorphingLabel.xcframework.zip from the Releases page. Then drag and drop it into your project.

Carthage

Add this line to your Cartfile: github "lexrus/LTMorphingLabel"
Read the official instruction

CocoaPods

Install the latest release of CocoaPods: gem install cocoapods
Add this line to your Podfile: pod 'LTMorphingLabel'
Install the pod: pod install

Usage

Change the class of a label from UILabel to LTMorphingLabel;
Programmatically set a new String to its text property.
To use interactively, call .pause() after changing .text property, and use updateProgress(progress: Float)to update the progress interactively.

Unit tests

Open the project with Xcode then press command + u.

Alternative

Even though this lib was used in a few products on App Store, it’s still an experimental project. Frankly, there’re some nice competitors out there guarantee both compatibility and stability. And the most outstanding one is ZCAnimatedLabel. I’d like to recommend it for production use.

And finally, an Android port.
