Ios 如何在Swift中将按钮标题传递给下一个视图控制器

我在viewDidLoad的循环中定义了几个按钮。它们位于滚动视图中的内容视图中

    for var i:Int = 0; i < colleges.count; i++ {

        let collegeButton = UIButton.buttonWithType(UIButtonType.System) as UIButton
        collegeButton.frame = CGRectMake(0, 0, self.contentView.frame.size.width, 30)
        collegeButton.center = CGPoint(x: self.contentView.center.x, y: 30 * CGFloat(i) + 30)
        collegeButton.setTitle(sortedColleges[i], forState: UIControlState.Normal)
        collegeButton.setTitleColor(UIColor.darkGrayColor(), forState: UIControlState.Normal)
        collegeButton.titleLabel?.font = UIFont(name: "Hiragino Kaku Gothic ProN", size: 15)
        collegeButton.addTarget(self, action: "collegeSelected:", forControlEvents: UIControlEvents.TouchUpInside)
        self.contentView.addSubview(collegeButton)
    }

注释行是失败的尝试

我还尝试了在按下按钮时调用的操作功能：

func collegeSelected(sender: UIButton!) {

    self.performSegueWithIdentifier("goToTableView", sender: self)

    //Set navigation title of next screen to title of button
    var buttonTitle = sender.titleLabel?.text
    println(buttonTitle)

}

使用发送器获取按钮标题是可行的，但我不知道如何将其传递给下一个视图控制器

非常感谢能够提供帮助的任何人。

在按钮功能中，将按钮作为序列的发送者传递：

func collegeSelected(sender: UIButton!) {
    self.performSegueWithIdentifier("goToTableView", sender: sender)
}

然后在

prepareForSegue

中，从发件人处获取按钮标题（即按钮）：

func collegeSelected(sender: UIButton!) {
    self.performSegueWithIdentifier("goToTableView", sender: sender)
}

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    let destViewController = segue.destinationViewController as videosTableView

    if let buttonTitle = (sender as? UIButton)?.titleLabel?.text {
        destViewController.title = buttonTitle
    }
}
