如何在停止标签处获取字符串？

Question

我正在使用iCarosuel并且我有一个填充的数组，它会显示，但是当我滚动并停止某个值时，我希望打印该值。无论卷轴停止的值是什么，都打印该值。

   func carousel(carousel: iCarousel, viewForItemAtIndex index: Int, reusingView view: UIView?) -> UIView {
    var labels: UILabel
    var itemView: UIImageView

    if(view == nil){
        itemView = UIImageView(frame:CGRect(x:0, y:0, width:400, height:100))
        itemView.image = UIImage(named: "page")
        itemView.contentMode = .Center

        labels = UILabel(frame: itemView.bounds)
        labels.backgroundColor = UIColor.clearColor()
        labelsubject.textAlignment = .Center
        labels.textColor = UIColor.whiteColor()
        labels.tag = 1
        itemView.addSubview(labels)

    }else{
        itemView = view as! UIImageView;
        labels = itemView.viewWithTag(1) as! UILabel!

    }
    labels.text = "\(text[index])"

    return itemView
}

func carouselDidEndDragging(carousel: iCarousel, willDecelerate decelerate: Bool) {

    if !decelerate {
        print(carousel.currentItemIndex)
        //text[carousel.currentItemIndex]
    }
}

func carouselDidEndDecelerating(carousel: iCarousel) {
    print(carousel.currentItemIndex)
    //text[carousel.currentItemIndex]
}
