## Overview

SwiftySignature is a lightweight signature capturing framework written in Swift. SwiftySignature utilizeds the [SwiftyDraw](https://github.com/Awalz/SwiftyDraw) drawing framework to get accurate, smooth drawings.

## Requirements
* iOS 8.0+
* Swift 3.0

## License

SwiftySignature is available under the BSD license. See the LICENSE file for more info.

## Installation

### Cocoapods:

SwiftySignature is available through [CocoaPods](http://cocoapods.org). To install
it, simply add the following line to your Podfile:

```ruby
pod "SwiftySignature"
```

### Manual Installation:

Simply copy the contents of the Source folder into your project.

## Usage

Using SwiftySignature is very simple:

### Getting Started:

If you have installed via Cocoapods, you will need to import the module into your Swift file:

import SwiftySignature

Create a SignatureView either through interface builder, or through code:

let signatureView = SignatureView(frame: frame)
    self.view.addSubview(signatureView)
    
By default, the view will automatically respond to touch gestures and begin drawing. Drawing can be disbaled by the **drawingEnabled** property.

### Capturing a Signature

Once a user has finished with their signature, you can call the **captureSignature** function on the signature view. When this function is called, the **SignatureViewDelegate** method **SignatureViewDidCaptureSignature(view:signature:)** will return an optional **Signature**:

func SignatureViewDidCaptureSignature(view: SignatureView, signature: Signature?) {
    	if signature != nil {
       	print(signature!) // 
       }
    }
    
The returned Signature object may be nil if the canvas is blank. This can be checked prior to calling **captureSignature** with the **signaturePresent** property.

The **Signature** object contains both the signature **image** and the **date** that the signature was captured.

The SignatureView can be cleared entirely using the **clearCanvas** function:

signatureView.clearCanvas()
    
## Properties

* **lineColor** - Signature stroke color. Accepts any UIColor. Default is black
* **lineWidth** - Signature stroke width. Accepts any positive CGFloat. Default is 3.0
* **lineOpacity** - Signature stroke opacity. Accepts a CGFloat between 0.0 and 1.0
* **drawingEnabled** - Sets whether or not swipe gestures will be drawn onto the view. Default is true
* **signaturePresent** (get-only) - Returns whether a signature is present or not. 
* **signatureIsOpaque** - Sets whether or not the Signature image is on an opaque, white, background or transparent
    
## Delegate

* **SignatureViewDidCaptureSignature(view:signature:)** - Called when the **captureSignature** function is called. Returns an optional **Signature** object
* **SignatureViewDidBeginDrawing(view:)** - Called when a user begins drawing a line segment on the SignatureView. Can be called multiple times.
* **SignatureViewIsDrawing(view:)** - Called when a user is drawing on the SignatureView. Will be called multiple times
* **SignatureViewDidFinishDrawing(view:)** - Called when a user finished drawing a line segment. Can be called mulitple times
* **SignatureViewDidCancelDrawing(view:)** - Called when a user cancels drawing a line segment
