Configs

Setup programmatically :

       // sets animation type
        self.allInOneview?.animationType = LoadingType.all.rawValue
        
        // sets the color that fills the button after percent value changed
        self.allInOneview?.backgroundFillColor = .purple
        
        // sets the indicator color above the button
        self.allInOneview?.loadingColor = .yellow

        // sets the indictore view color (dark or light) inside the button
        self.allInOneview?.indicatorViewStyle = .light
        
        // some animations have image inside (e.g appstore pause image), this line sets that image
        self.allInOneview?.pauseImage = UIImage(named: "pause.png")
        
        // starts loading animation
        self.allInOneview?.startLoading()
        
        // some animations have filling background, or change the circle stroke, this sets the filling percent, number is something between 0 to 100
        self.allInOneview?.fillTheButton(with: 10)
        
        // some animations have circular loading , this sets the percents of circle that are completed, number is something between 0 to 100
        self.allInOneview?.fillTheCircleStrokeLoadingWith(percent: 25)

4 Phases Animation :

        // setup colors, titles and images
        self.fourPhases?.loadingColor = UIColor(red:0.38, green:0.66, blue:0.09, alpha:1.0)
        self.fourPhases?.fourPhases = (
            // normal phase
            LoadyAnimationOptions.FourPhase.Phases.normal(title: "Lock", image: UIImage(named: "unlocked"), background: UIColor(red:0.00, green:0.49, blue:0.90, alpha:1.0)),
            
            // loading phase
            LoadyAnimationOptions.FourPhase.Phases.loading(title: "Waiting...", image: UIImage(named: ""), background: UIColor(red:0.17, green:0.24, blue:0.31, alpha:1.0)),
            
            // success phase
            LoadyAnimationOptions.FourPhase.Phases.success(title: "Activated", image: UIImage(named: "locked"), background: UIColor(red:0.15, green:0.68, blue:0.38, alpha:1.0)),
            
            // error phase
            LoadyAnimationOptions.FourPhase.Phases.error(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.fourPhases?.startLoading()

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

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
