在 Swift 中检查 UIButton 标题

checking UIButton Title in Swift(在 Swift 中检查 UIButton 标题)

问题描述

我有一个按钮，按钮的标题是一个整数.

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

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

我正在尝试检查按钮的标题，以便将其转换为整数并在 if 语句中使用它，但无法使其工作.

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!)

我是 swift 新手，我什至可能对我的方法有疑问，我们将不胜感激.

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