ParticlesLoadingView
Description
With ParticlesLoadingView
you can create your own amazing SpriteKit
particles animations with the Xcode's built-in Particle Emitter Editor that looks like the following picture.
Go ahead and create your own particles animation by doing File
Usage
To see it in action, run the example project, clone the repo, and run pod install
from the Example
directory first. The example project shows how to set up ParticlesLoadingView
in a few different ways.
The easiest way to add a particles animation around the border of any UIView
subclass is to use the extension method as follows:
let view = ... // Your UIView subclass here
view.addParticlesAnimation(effect: ParticleEffect.Fire) // Use a built-in effect
view.addParticlesAnimation(emitter: emitter) // Use your own SKEmitterNode
You can also use the already provided ParticlesLoadingView
class to create an animation. Instantiate it by code or in Storyboard and select a built-in ParticleEffect
or set the scene.emitterNode
to your custom SKEmitterNode
object.
var loadingView: ParticlesLoadingView = {
let view = ParticlesLoadingView(frame: 0, y: 0, width: 75, height: 75))
view.particleEffect = .Spark
view.duration = 1.5
view.layer.cornerRadius = 15.0
return view
}()
// OR provide your own SKEmitterNode
let emitter = NSKeyedUnarchiver.unarchiveObjectWithFile(NSBundle.mainBundle().pathForResource("Spark", ofType: "sks")!) as? SKEmitterNode
if let emitter = emitter {
loadingView.scene.emitterNode = emitter
loadingView.startAnimating()
}
Customizations
/// Duration in seconds of the animation to complete a tour on the border of the view.
public var duration = 2.0
/// The size of each particle image. This value is used to calculate the inner padding of the view path so that the emitted particles are visible.
public var particlesSize: CGFloat = 5.0
/// The emitter of particles that is animated along the border of the view.
public var emitterNode: SKEmitterNode? = nil
You can provide your own particle emitter node by designing an animation with the particle emitter editor and creating a SKEmitterNode
.
If you want to customize it further than that, the project is documented so go ahead and
If you think a feature should be included in this project, submit a PR or open a new issue.
