Set different font as per title and subtitle in UIlabel IBDesignable - ios

Question

I had created the custom class for uilabel with below code:
#IBDesignable
public class CustomUILabel: UILabel {
public override func awakeFromNib() {
super.awakeFromNib()
configureLabel()
}
public override func prepareForInterfaceBuilder() {
super.prepareForInterfaceBuilder()
configureLabel()
}
func configureLabel() {
textColor = .white
font = UIFont(name: Constants.regularFontName, size: 14)
}
}
This help me to set the font through out the application.But i wanted to create different bold font type for title and regular font for subtitle.
Is this possible only with one file ?
Or i need to create different Extension for that type of UIlabel

You could for example add a custom style property like this:
#IBDesignable
public class CustomUILabel: UILabel {
enum CustomUILabelStyle {
case title, subtitle
var font: UIFont? {
switch self {
case .title:
return UIFont(name: Constants.boldFontName, size: 14)
case .subtitle:
return UIFont(name: Constants.regularFontName, size: 14)
}
}
var textColor: UIColor {
switch self {
// add cases if you want different colors for different styles
default: return .white
}
}
}
var style: CustomUILabelStyle = .title {
didSet {
// update the label's properties after changing the style
if style != oldValue {
configureLabel()
}
}
}
public override func awakeFromNib() {
super.awakeFromNib()
configureLabel()
}
public override func prepareForInterfaceBuilder() {
super.prepareForInterfaceBuilder()
configureLabel()
}
func configureLabel() {
font = style.font
textColor = style.textColor
}
}
You use it like this:
let label = CustomUILabel()
label.style = .title
// label.style = .subtitle
