PocketSVG

An Objective-C class that converts Scalable Vector Graphics (SVG) into:

• CGPaths
• CAShapeLayers
• UIBezierPaths
• NSBezierCurves

This makes it easy to create vector-based paths and shapes in your iOS or OS X apps.

Feedback, improvements, and pull requests are welcome.

Usage

Drag and drop the SVG files into your Xcode project.

###Swift

1. Xcode will ask "Would you like to configure an Objective-C bridging header?", Click Yes.
2. Add this line to the bridging header file: #import "PocketSVG.h"
3. Follow these simple steps:

//1: Turn your SVG into a CGPath:
let myPath = PocketSVG.pathFromSVGFileNamed("BezierCurve1").takeUnretainedValue()

//2: To display it on screen, you can create a CAShapeLayer
//and set myPath as its path property:
let myShapeLayer = CAShapeLayer()
myShapeLayer.path = myPath

//3: Fiddle with it using CAShapeLayer's properties:
myShapeLayer.strokeColor = UIColor.redColor().CGColor
myShapeLayer.lineWidth = 3
myShapeLayer.fillColor = UIColor.clearColor().CGColor

//4: Display it!
self.view.layer.addSublayer(myShapeLayer)

###Objective-C

//1: Turn your SVG into a CGPath:
CGPathRef myPath = [PocketSVG pathFromSVGFileNamed:@"BezierCurve1"];

//2: To display it on screen, you can create a CAShapeLayer
//and set myPath as its path property:
CAShapeLayer *myShapeLayer = [CAShapeLayer layer];
myShapeLayer.path = myPath;

//3: Fiddle with it using CAShapeLayer's properties:
myShapeLayer.strokeColor = [[UIColor redColor] CGColor];
myShapeLayer.lineWidth = 4;
myShapeLayer.fillColor = [[UIColor clearColor] CGColor];

//4: Display it!
[self.view.layer addSublayer:myShapeLayer];

Useful Documentation

• The 'path' element of an SVG – from the SVG specification. PocketSVG uses the data in the SVG's d= attribute, which defines the outlines of shapes.
• Core Graphics Paths – from Apple's Quartz 2D Programming Guide.
• CGPath - Class Reference.
• CAShapeLayers – Class Reference. Tells you which properties of the shape/path can be manipulated.
• Drawing Shapes Using Bezier Paths – From Apple's Drawing and Printing Guide for iOS.

To Do

• Support for SVG's Basic Shapes.
• Support for SVGs with more than one path (currently PocketSVG renders the last path).
• Improve parser efficiency.

Support

Please ask questions and report bugs on the project's Issues Page.
