Once you have your Swift package set up, adding EFAutoScrollLabel as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "https://github.com/EFPrefix/EFAutoScrollLabel.git", .upToNextMinor(from: "5.1.3"))
]

Setup

Simply initialize a EFAutoScrollLabel the same way you set up a regular UILabel:

let myLabel = EFAutoScrollLabel(frame: CGRect(x: 10, y: 10, width: 200, height: 40))
self.view.addSubview(myLabel)

Use

1. Import EFAutoScrollLabel module where you want to use it:

import EFAutoScrollLabel

2. Initialize a EFAutoScrollLabel and set some parameter:

let myLabel = EFAutoScrollLabel(frame: CGRect(x: 10, y: 10, width: 200, height: 40))
myLabel.backgroundColor = UIColor(red: 253.0 / 255.0, green: 255.0 / 255.0, blue: 234.0 / 255.0, alpha: 1)
myLabel.textColor = UIColor(red: 249.0 / 255.0, green: 94.0 / 255.0, blue: 22.0 / 255.0, alpha: 1)
myLabel.font = UIFont.systemFont(ofSize: 13)
myLabel.labelSpacing = 30                       // Distance between start and end labels
myLabel.pauseInterval = 1.7                     // Seconds of pause before scrolling starts again
myLabel.scrollSpeed = 30                        // Pixels per second
myLabel.textAlignment = NSTextAlignment.left    // Centers text when no auto-scrolling is applied
myLabel.fadeLength = 12                         // Length of the left and right edge fade, 0 to disable
myLabel.scrollDirection = EFAutoScrollDirection.left
self.view.addSubview(myLabel)

3. AutoLayout is also supported.

PS

The first version of EFAutoScrollLabel is converted from AutoScrollLabel.
