# ScratchCard
<img src="https://raw.githubusercontent.com/joehour/ScratchCard/swift3.0/ScratchCard/result.gif" width="307" height="550" />

Requirements
----------

- iOS 8.0+
- Xcode 8.0+ Swift 3

## Installation

#### CocoaPods

Check out [Get Started](https://guides.cocoapods.org/using/getting-started.html) tab on [cocoapods.org](http://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:
```swift
    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:
```swift
   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:
```swift
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)

}
}
```
