swift---不同字体大小不同颜色label富文本设置

agreeDeal = UILabel()

//富文本,不同字体颜色大小和颜色

let labelString = "登录注册，表示您同意《服务条款及隐私政策》"as NSString

let rang = labelString.rangeOfString("《")

let firstRang = NSMakeRange(0, rang.location)

let secondRang = NSMakeRange(rang.location, labelString.length - rang.location)

let labelText = NSMutableAttributedString(string: labelString as String as String)

labelText.addAttributes([NSForegroundColorAttributeName:UIColor.init(white: 1, alpha: 0.8),NSFontAttributeName:UIFont.boldSystemFontOfSize(12)], range: firstRang)

labelText.addAttributes([NSForegroundColorAttributeName:UIColor.redColor(),NSFontAttributeName:UIFont.boldSystemFontOfSize(12)], range: secondRang)

agreeDeal.attributedText = labelText

agreeDeal.textAlignment = .Center

agreeDeal.numberOfLines = 0

bottomView.addSubview(agreeDeal)

特殊例外：第二部分是传过来的值

//富文本,不同字体颜色大小和颜色
