Swift中對UILable的文字大小衅金、顏色、行間距簿煌、富文本屬性等設(shè)置

goodsLab.text = "潛水艇防臭淋雨房地漏套餐地漏3+直接頭1+洗衣機龍頭*1LTK50—/10X/L702X"
goodsLab.textColor = UIColor.convertHexColorToUIColor("666666")

    goodsLab.font = UIFont.systemFontOfSize(30.px)

    //設(shè)置行間距

    let attributedString = NSMutableAttributedString(string:goodsLab.text!)

    let paragraphStyle = NSMutableParagraphStyle()

    paragraphStyle.lineSpacing = 15.px

    attributedString.addAttribute(NSParagraphStyleAttributeName, value: paragraphStyle, range: NSMakeRange(0, NSString(string: goodsLab.text!).length))

    goodsLab.attributedText = attributedString

    goodsLab.adjustsFontSizeToFitWidth = true

    goodsLab.numberOfLines=0

    goodsLab.translatesAutoresizingMaskIntoConstraints = false

    contentView.addSubview(goodsLab)

//富文本設(shè)置
var attributeString = NSMutableAttributedString(string:"welcome to hangge.com")
//從文本0開始6個字符字體HelveticaNeue-Bold,16號
attributeString.addAttribute(NSFontAttributeName, value: UIFont(name: "HelveticaNeue-Bold", size: 16)!,range: NSMakeRange(0,6))
//設(shè)置字體顏色
attributeString.addAttribute(NSForegroundColorAttributeName, value: UIColor.blueColor(),range: NSMakeRange(0, 3))
//設(shè)置文字背景顏色
attributeString.addAttribute(NSBackgroundColorAttributeName, value: UIColor.greenColor(),range: NSMakeRange(3,3))

    msgLabel.attributedText = attributeString

let label1=UILabel(frame: CGRectMake(30, 120, 300, 36))
