Beautiful & simple parallax effects for your UI. 🌁 Perfect for Onboarding & Login/Signup screens - Recreate the well-known iOS wallpaper animation by dividing your ViewController in background, middleground and foreground elements which each receive different motionEffects.

Usage

SimpleParallax works by extending UIView. In order to apply a Parallax-MotionEffect to one of your UIView-objects, simply call one of the following methods:

• addBackgroundPxEffect()
• addMiddlegroundPxEffect()
• addForegroundPxEffect()

Furthermore, you can specify the strength of the Parallax-effect:
If you don't pass the strength as an argument, .Mid is used by default.

enum ParallaxStrength {
    case Low
    case Mid
    case High
}  

Example implementation in viewDidLoad():

  
override func viewDidLoad() {
        super.viewDidLoad()
        //Lets assign our Backgrounds:
        background2.addBackgroundPxEffect(strength: .Low)
        background1.addBackgroundPxEffect(strength: .Mid)
        
        //Lets assign our Middleground:
        titleLabel.addMiddlegroundPxEffect()
        
        //Lets assign our Foreground:
        startButton.addForegroundPxEffect(strength: .High)
    }
