addSubview dans une SpringView

Salut tout le monde,

I use the Spring library (https://github.com/MengTo/Spring) to add iOS animations to my Swift project. I have a custom subclass ChooseButton of SpringView and I want to add a subview (mySubView in this case) to this view :

class ChooseButton: SpringView {

enum TypeButton {

case YES, NO

}



var type:TypeButton!

var size:CGFloat = 90



var enabled: Bool!

var delegateButton: ChooseButtonDelegate?



init (type: TypeButton) {

super.init(frame: CGRectMake(0,0,size,size))

self.type = type

enabledButton()

if type == TypeButton.YES {

self.backgroundColor = CustomColor.Emeralde

self.center = CGPointMake(gScreenSize.width*3/4, gScreenSize.height-self.frame.size.height)

} else {

self.backgroundColor = CustomColor.Alizarin

self.center = CGPointMake(gScreenSize.width/4, gScreenSize.height-self.frame.size.height)

}

self.layer.cornerRadius = size/2



var mySubView = UIView(frame: frame)

mySubView.backgroundColor = UIColor.blackColor()

addSubview(mySubView)

}

But my Subview does not shows up... I can't see why.

Merci pour votre aide et bonne journée !
