让TTTAttributedLabel打印粗体

Question

第一次尝试使用TTTAttributedLabel框架。我想使用它使我的UILabel的一部分以粗体字体打印，而另一部分则打印为轻量字体：

let messageLabelString = "\(notificationSenderName) would like to rent your \(notificationItem). Approve?"
cell.messageLabel.text = messageLabelString
let nsString = messageLabelString as NSString
let range = nsString.rangeOfString(notificationSenderName)
let url = NSURL(string: "test")
cell.messageLabel.addLinkToURL(url, withRange: range)
cell.messageLabel.delegate = self

现在看起来是这样的：

然而，我不想要蓝色和下划线字体，我只是想得到一个黑色和粗体字体。我该怎么做？

做了我想做的事：

let messageLabelString = "\(notificationSenderName) would like to rent your \(notificationItem). Approve?"
            cell.messageLabel.text = messageLabelString
            let nsString = messageLabelString as NSString
            let range = nsString.rangeOfString(notificationSenderName)
            let url = NSURL(string: "test")

            let subscriptionNoticeLinkAttributes = [
                NSFontAttributeName: UIFont(name:"JohnstonITCPro-Bold", size:15)!
                ]

            cell.messageLabel.linkAttributes = subscriptionNoticeLinkAttributes
            cell.messageLabel.addLinkToURL(url, withRange: range)
            cell.messageLabel.delegate = self
