  • [x] Documentation

  • Xcode 9.0+
  • Swift 5 (Magnetic 3.x), Swift 4 (Magnetic 2.x), Swift 3 (Magnetic 1.x)

Usage

A Magnetic object is an SKScene.

To display, you present it from an SKView object.

import Magnetic

class ViewController: UIViewController {

    var magnetic: Magnetic?

    override func loadView() {
        super.loadView()

        let magneticView = MagneticView(frame: self.view.bounds)
        magnetic = magneticView.magnetic
        self.view.addSubview(magneticView)
    }

}

Properties

var magneticDelegate: MagneticDelegate? // magnetic delegate
var allowsMultipleSelection: Bool // controls whether you can select multiple nodes. defaults to true
var selectedChildren: [Node] // returns selected chidren

Nodes

A Node object is a SKShapeNode subclass.

Interaction

// add circular node
let node = Node(text: "Italy", image: UIImage(named: "italy"), color: .red, radius: 30)
magnetic.addChild(node)

// add custom node
let node = Node(text: "France", image: UIImage(named: "france"), color: .blue, path: path, marginScale: 1.1)
magnetic.addChild(node)

// remove node
node.removeFromParent()

Properties

var text: String? // node text
var image: UIImage? // node image
var color: UIColor // node color

Animations

override func selectedAnimation() {
    // override selected animation
}

override func deselectedAnimation() {
    // override deselected animation
}

override func removedAnimation(completion: @escaping () -> Void) {
    // override removed animation
}

Delegation

The MagneticDelegate protocol provides a number of functions for observing the current state of nodes.

func magnetic(_ magnetic: Magnetic, didSelect node: Node) {
    // handle node selection
}

func magnetic(_ magnetic: Magnetic, didDeselect node: Node) {
    // handle node deselection
}

Customization

Subclass the Node for customization.

For example, a node with an image by default:

class ImageNode: Node {
    override var image: UIImage? {
        didSet {
            texture = image.map { SKTexture(image: $0) }
        }
    }
    override func selectedAnimation() {}
    override func deselectedAnimation() {}
}
