Requirements

  • iOS 8.0+
  • Xcode 8.0+ Swift 3

Installation

CocoaPods

Check out Get Started tab on cocoapods.org.

To use ScratchCard in your project add the following ‘Podfile’ to your project

pod 'ScratchCard', '~> 1.1.3'

Then run:

pod install

Source Code

Copy the ScratchView.swift and ScratchUIView.swift to your project.

Go ahead and import ScratchCard to your file.

Example

Please check out the Example project included.

Usage

  • Sample:

    import ScratchCard
    
    class ViewController: UIViewController {
    
    var scratchCard: ScratchUIView!
    override func viewDidLoad() {
        super.viewDidLoad()
    
        scratchCard  = ScratchUIView(frame: CGRect(x:50, y:80, width:320, height:480),Coupon: "image.jpg", MaskImage: "mask.png", ScratchWidth: CGFloat(40))
    
        self.view.addSubview(scratchCard)
        }
    }

Scratched Percent

It is easy to get the scratched percent.

  • Sample:
    let scratchPercent: Double = scratchCard.getScratchPercent()

Handle Scratch Event

It is easy to handle the scratch event(ScratchBegan, ScratchMoved, and ScratchEnded).

You can get the Scratch Position in the ScratchCard.

Please set the ScratchUIViewDelegate in your code.

  • Sample:

    class ViewController: UIViewController, ScratchUIViewDelegate {
    
    var scratchCard: ScratchUIView!
    override func viewDidLoad() {
        super.viewDidLoad()
    
        scratchCard = ScratchUIView(frame: CGRect(x:50, y:80, width:320, height:480), Coupon: "image", MaskImage: "mask", ScratchWidth: CGFloat(40))
        scratchCard.delegate = self
    
        self.view.addSubview(scratchCard)
    }
    
    //Scratch Began Event(optional)
    func scratchBegan(_ view: ScratchUIView) {
        print("scratchBegan")
    
        ////Get the Scratch Position in ScratchCard(coordinate origin is at the lower left corner)
        let position = Int(view.scratchPosition.x).description + "," + Int(view.scratchPosition.y).description
        print(position)
    
    }
    
    //Scratch Moved Event(optional)
    func scratchMoved(_ view: ScratchUIView) {
        let scratchPercent: Double = scratchCard.getScratchPercent()
        textField.text = String(format: "%.2f", scratchPercent * 100) + "%"
        print("scratchMoved")
    
        ////Get the Scratch Position in ScratchCard(coordinate origin is at the lower left corner)
        let position = Int(view.scratchPosition.x).description + "," + Int(view.scratchPosition.y).description
        print(position)
    }
    
    //Scratch Ended Event(optional)
    func scratchEnded(_ view: ScratchUIView) {
        print("scratchEnded")
    
        ////Get the Scratch Position in ScratchCard(coordinate origin is at the lower left corner)
        let position = Int(view.scratchPosition.x).description + "," + Int(view.scratchPosition.y).description
        print(position)
    
    }
    }
