Rough lets you draw in a sketchy, hand-drawn-like, style. It is Swift clone of Rough.js. The library defines primitives to draw lines, curves, arcs, polygons, circles, and ellipses.
Xcode 9, iOS 10
Rough is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod 'Rough'
let canvas = roughView.canvas
canvas.rectangle(origin: CGPoint(x: 10, y: 10), width: 200, height: 100)
roughView.setNeedsDisplay()
canvas.circle(center: CGPoint(x: 80, y: 120), radius: 25)
canvas.ellipse(center: CGPoint(x: 300, y: 100), width: 150, height: 80)
canvas.line(from: CGPoint(x: 80, y: 120), to: CGPoint(x: 300, y: 100))
canvas.circle(center: CGPoint(x: 50, y: 50), radius: 40) { options in
options.fill = UIColor.red
} // fill with red hachure
canvas.rectangle(origin: CGPoint(x: 120, y: 15), width: 80, height: 80) { options in
options.fill = UIColor.red
}
canvas.circle(center: CGPoint(x: 50, y: 150), radius: 40) {
options in
options.fill = UIColor(red: 10/255.0, green: 150/255.0, blue: 10/255.0, alpha: 1.0)
options.fillWeight = 3 // thicker lines for hachure
}
canvas.rectangle(origin: CGPoint(x: 220, y: 15), width: 80, height: 80) { options in
options.fill = UIColor.red
options.hachureAngle = 60 // angle of hachure
options.hachureGap = 8
}
canvas.rectangle(origin: CGPoint(x: 120, y: 105), width: 80, height: 80) { options in
options.fill = UIColor(red: 1.0, green: 0, blue: 200/255.0, alpha: 0.2)
options.fillStyle = .solid // solid fill
}
canvas.rectangle(origin: CGPoint(x: 15, y: 15), width: 80, height: 80) { options in
options.roughness = 0.5
options.fill = UIColor.red
}
canvas.rectangle(origin: CGPoint(x: 120, y: 15), width: 80, height: 80) { options in
options.roughness = 2.8
options.fill = UIColor.blue
}
canvas.rectangle(origin: CGPoint(x: 220, y: 15), width: 80, height: 80) { options in
options.bowing = 6
options.stroke = UIColor.green
options.strokeWidth = 3
