can't pass value pressed the button in swift

in swift I can't pass the value that is passed by pressing the button and I have to print it. I use an if and it always prints the first value.

if zeroPctButton.titleLabel!.text! == "0%" {
                print("0.0")
        } else if tenPctButton.titleLabel!.text! == "10%" {
                    print("0.1")
                }else {
                    print("0.2")
                }
