func heightForLabel(text:String, font:UIFont, width:CGFloat) -> CGFloat

    {

        let label:UILabel = UILabel(frame: CGRectMake(0, 0, width, CGFloat.max))

        label.numberOfLines = 0

        label.lineBreakMode = NSLineBreakMode.ByWordWrapping

        label.font = font

        label.text = text

        

        label.sizeToFit()

        return label.frame.height

let font = UIFont(name: "Verdana", size: 12)

        var detailHeight = heightForLabel("Your String", font: font!, width: self.scrollView.bounds.size.width-10)
