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.

also you should use
sender.currentTitle
