How to use addTarget method in swift 3

Question

here is my button object

    let loginRegisterButton:UIButton = {
    let button = UIButton(type: .system)
    button.backgroundColor = UIColor         


        

Answer 1

Try this

button.addTarget(self, action:#selector(handleRegister()), for: .touchUpInside). 

Just add parenthesis with name of method.
