checking UIButton Title in Swift

问题

I have a button and title of the button is an integer.

correctAnswer = randomNumber1 + randomNumber2
button1.setTitle("\(correctAnswer)", forState: UIControlState.Normal)

I am trying to check the title of the button so convert it to an integer and use it in an if statement, but couldn't make it work.

button1.titleLabel?.text?.toInt()
    if button1.titleLabel == correctAnswer { //most probably I am making a mistake here.
        scoring() } else {
        println(button1.titleLabel?.text!)

I am new to swift , I might even have problem with my approach, your help will be appreciated.
