To do this job in storyboard (Interface Builder Inspector)
With help of IBDesignable
, we can add more options to Interface Builder Inspector for UIButton
and tweak them on storyboard. First, add the following code to your project.
@IBDesignable extension UIButton {
@IBInspectable var borderWidth: CGFloat {
set {
layer.borderWidth = newValue
}
get {
return layer.borderWidth
}
}
@IBInspectable var cornerRadius: CGFloat {
set {
layer.cornerRadius = newValue
}
get {
return layer.cornerRadius
}
}
@IBInspectable var borderColor: UIColor? {
set {
guard let uiColor = newValue else { return }
layer.borderColor = uiColor.cgColor
}
get {
guard let color = layer.borderColor else { return nil }
return UIColor(cgColor: color)
}
}
}
Then simply set the attributes for buttons on storyboard.
