Gravity

--

Gravity is a simple Swift Package to add gravity to UI objects easily.

--

How to use:

Add a new Swift Package from XCode and paste the url of this repository (https://github.com/elpsk/Gravity).

Next, import the SDK:

import GravitySPM

Add your IBOutlets or your custom views:

@IBOutlet weak var label1: UILabel!
@IBOutlet weak var label2: UILabel!
@IBOutlet weak var button1: UIButton!
@IBOutlet weak var button2: UIButton!
@IBOutlet weak var switch1: UISwitch!
@IBOutlet weak var switch2: UISwitch!

var gravity: Gravity?

Next, attach your desidered items to a new UIDynamicItem array:

let gravityItems: [UIDynamicItem] = [
	label1, label2, button1, button2, switch1, switch2
]

and create a new Gravity object with desidered params:

gravity = Gravity(
    gravityItems: gravityItems,
    collisionItems: nil,
    referenceView: self.view,
    boundary: UIBezierPath(rect: self.view.frame),
    queue: nil)

Now you're ready to enable() or disable() the behavior.

@IBAction func didEnablePressed(_ sender: Any) {
    gravity?.enable()
}

@IBAction func didDisablePressed(_ sender: Any) {
    gravity?.disable()
}

Have fun.
