UILabel的多色着色與保存lineHeight

Question

大家好我有一個UILabel與lineHeight 1.2，需要它是多彩的，但只要我改變文本的顏色，lineheight的值就成爲默認值。 這裏是我的功能：

func configTopLabel(label: UILabel, localString: String, color: UIColor) { 

    var myString:NSString = localString 
    var myMutableString = NSMutableAttributedString() 
    myMutableString = NSMutableAttributedString(string: myString as String, attributes: [NSFontAttributeName:UIFont(name: "GothamPro-Bold", size: 22.0)!]) 
    let location = localString.characters.count - 3 
    myMutableString = NSMutableAttributedString(string: myString as String, attributes: [NSFontAttributeName:UIFont(name: "GothamPro-Bold", size: 22.0)!]) 
    myMutableString.addAttribute(NSForegroundColorAttributeName, value: color, range: NSRange(location: location,length: 3)) 
    label.setLineHeight(1.2) 
    label.attributedText = myMutableString 
}
