A lightweight UILabel subclass with character by character typewriter like animation in Swift, super simple to use

iOS上自带逐字打印动画效果的UILabel

0. Copy and paste CLTypingLabel.swift to your xcode project.

1. Install the latest release of CocoaPods: gem install cocoapods
2. Add this line to your Podfile: pod 'CLTypingLabel'
3. Install the pod: pod install

1. Change the class of a label from UILabel to CLTypingLabel;

@IBOutlet weak var myTypeWriterLabel: CLTypingLabel!

At runtime, set text of the label will trigger animation automatically:

myTypeWriterLabel.text = "This is a demo of typing label animation..."

You can also trigger what you need after animation is finished:

myTypeWriterLabel.onTypingAnimationFinished = {
	//code goes here
}

Also works on attributedText:

myTypeWriterLabel.attributedText = NSAttributedString(string: "This is an attributed text typing animation...", attributes: attr)

You can pause the typing animation at any time:

myTypeWriterLabel.pauseTyping() //this will pause the typing animation
myTypeWriterLabel.continueTyping() //this will continue paused typing animation

And customize time interval between each character:

myTypeWriterLabel.charInterval = 0.08 //optional, default is 0.1
