How to Use

WaveAnimationView can install to your app just by writting 3 lines as follows:

import UIKit
import WaveAnimationView

class ViewController: UIViewController {

    var wave: WaveAnimationView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 1
        wave = WaveAnimationView(frame: CGRect, color: UIColor)
        
        //superView.addSubView(WaveAnimationView)
        
        // 2
        wave.startAnimation()
        
    }
    
    override func viewDidDisAppear() {
        super.viewDidDisAppear(animated)
        
        // 3 - Be sure to read the following Attension!
        wave.stopAnimation()
        
    }
}

⚠️Attension

WaveAnimationView is animated by ScheduledTimer, not UIView.animate or Core Animation.

//Start wave Animation
open func startAnimation() {
    timer = Timer.scheduledTimer(timeInterval: 0.035, target: self, selector: #selector(waveAnimation), userInfo: nil, repeats: true)
}

Therefore, Please be sure to call this method at ViewDidDisAppear or deinit in ViewController. If it isn't called, Memory Leaks occurs by Timer

open func stopAnimation() {
    timer.invalidate()
}

Options

Front/Back FillColor

Wave's fillColor is possible to be set fillColors separately.

let wave = WaveAnimationView(frame: CGRect, frontColor: UIColor, backColor: UIColor)

Set one Color

let wave = WaveAnimationView(frame: CGRect, color: UIColor)

MaskImage

Possible to mask the WaveAnimationView just by setting an image containing Solid and Alpha Areas.

let wave = WaveAnimationView(frame: CGRect, color: UIColor)
wave.maskImage = UIImage(named: "image name")

Set/GetProgress

Progress are set and gotten in the same way as UIProgressView

・Get Progress

let wave = WaveAnimationView(frame: CGRect, color: UIColor)
wave.progress = 1.0 //0.0 .. 1.0, default is 0.5

・Set Progress

//Example: UISlider
@IBAction func slide(_ sender: UISlider) {

     self.wave.setProgress(to: sender.value //0.0 .. 1.0)
     
}
