4 Phases Animation :

        self.fourPhases?.loadingColor = UIColor(red:0.38, green:0.66, blue:0.09, alpha:1.0)
        self.fourPhases.loadingColor = UIColor(red:0.38, green:0.66, blue:0.09, alpha:1.0)
			self.fourPhases.setPhases(phases: .init(
				normalPhase:
			(title: "Lock", image: UIImage(named: "unlocked"), background: UIColor(red:0.00, green:0.49, blue:0.90, alpha:1.0)), loadingPhase:
			(title: "Waiting...", image: nil, background: UIColor(red:0.17, green:0.24, blue:0.31, alpha:1.0)),
				successPhase:
			(title: "Activated", image: UIImage(named: "locked"), background: UIColor(red:0.15, green:0.68, blue:0.38, alpha:1.0)), errorPhase:
			(title: "Error", image: UIImage(named: "unlocked"), background: UIColor(red:0.64, green:0.00, blue:0.15, alpha:1.0))
				)
			)
        
        // then later in your code after user click on the button just call, this line take the button to loading phase, 
        self.fourPhasesLoadyButton?.startLoading()

        // in loading phase three different stage is available, you can cancel the loading by calling
        self.fourPhasesLoadyButton?.normalPhase()
        
        // you can take the button to success phase by calling
        self.fourPhasesLoadyButton?.successPhase()
        
        // you can take the button to error phase by calling

BONUS - NVActivityIndicatorView

if you are a fan of NVActivityIndicatorView, its very easy to integrate it with loady, you can replace our default iOS indicatorView with NVActivityIndicatorView <3 now we have a new property which accepts LoadyActivityIndicator Protocol, just set it with your favorite activity indicator view like below

// first conform to the LoadyActivityIndicator protocol like this
extension NVActivityIndicatorView : LoadyActivityIndicator {
    
}

// then replace loady default activity indicator with yours
let nv = NVActivityIndicatorView(frame: .zero)
nv.type = .circleStrokeSpin
nv.color = .red
nv.padding = 12
self.loadyButton?.activiyIndicator = nv
