How can I add a target to my button in an extension? - ios

Question

I wrote an extension to display an empty state if my view controller is empty. I also wanted to add a UIButton() with a target. How can I implement the addTarget action for my button within the extension? (F.e. a simple "Hello World" or what ever I need)
extension UITableView{
func setEmptyView(title: String, message: String) {
// handling states
button.setTitle("+ Add New Documentation", for: .normal)
button.titleLabel!.font = UIFont(name: "Roboto-Regular", size: 24)
button.setTitleColor(UIColor(hex: "BDC86F"), for: .normal)
button.backgroundColor = UIColor(hex: "506182")
button.addTarget...
//more code
emptyView.addSubview(button)
}
}

I have achieved the same thing for UIView extension. Hope, It will help you and I assume that you're able to convert it for UITableView
Code:
extension UIView{
func setEmptyView(title: String, message: String) {
let emptyView = UIView(frame: self.bounds)
// handling states
let button = UIButton(frame: emptyView.bounds)
button.setTitle("+ Add New Documentation", for: .normal)
button.titleLabel!.font = UIFont(name: "Roboto-Regular", size: 24)
button.setTitleColor(UIColor.red, for: .normal)
button.backgroundColor = UIColor.black
button.addTarget(self, action: #selector(btnTapEvent(sender:)), for: .touchUpInside)
emptyView.addSubview(button)
//more code
self.addSubview(emptyView)
}
#objc func btnTapEvent(sender:UIButton){
print("btnTapEvent")
}
}
