Setting up Components

Titles to be shown initilly, before scratch starts

controller.scratchCardView.doneButtonTitle = "Gift to a friend"
controller.scratchCardView.scratchCardTitle = "Earn up to ₹1,0000"
controller.scratchCardView.scratchCardSubTitle = "From Google Pay \nEarned for paying \nGokul"

Title to be show after scratch ends,

controller.scratchCardView.afterScratchDoneButtonTitle = "Done"
controller.scratchCardView.afterScratchTitle = "Woohoo!"
controller.scratchCardView.afterScratchSubTitle = "Expect payment within a weak."

Top layer image view,

controller.scratchCardView.topLayerImage = UIImage(named:"scratch_image")!

Bottom layer image view (one that will be reviled after scratching ends),

controller.scratchCardView.bottomLayerView = UIImageView(image: UIImage(named: "cash_back"))

Can customise scratch size and shape (.round, .square, .butt),

controller.scratchCardView.scratchCardImageView.lineWidth = 50
controller.scratchCardView.scratchCardImageView.lineType = .round
