Requirements

iOS 13.0+ (Magnetic 3.3.x), iOS 9.0+ (Magnetic 3.2.1)
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() {}

}
