truncationToken的值设置无效

[lxm1799]

使用BSText实现文本展开收缩的时候，设置truncationToken值，打印string值显示为空。
代码：
func addSeeMoreActionWithText(text:String,label:BSLabel,font:UIFont,isMore:Bool) -> NSAttributedString {

    label.attributedText = text.withAttributes([.font(font),.textColor(.Color101010)])
    
    let moreStr = isMore ? "收起":"查看全部"
    let moreAttributedText = NSMutableAttributedString.init(string: "..." + moreStr)
    
    let moreTextRange = NSRange(location: 3, length: moreStr.count)
    moreAttributedText.addAttributes([.font(font),.textColor(.Color101010)], range: NSRange(location: 0, length: 2))
    moreAttributedText.addAttributes([.font(font),.textColor(.red)], range: moreTextRange)
    
    let textHighlight = TextHighlight()
    moreAttributedText.bs_set(textHighlight: textHighlight, range: moreTextRange)
    textHighlight.tapAction = {(containerView,text,range,rect) in
        print("2222")
    }
    
    moreAttributedText.bs_font = font
    let seeMoreLabel = BSLabel()
    seeMoreLabel.attributedText = moreAttributedText
    seeMoreLabel.sizeToFit()

    let truncationToken = NSAttributedString.bs_attachmentString(with: seeMoreLabel, contentMode: .center, attachmentSize: seeMoreLabel.frame.size, alignTo: font, alignment: .top)
    
    print("\(String(describing: truncationToken?.string)),\(truncationToken?.mutableString)")
    
    if truncationToken != nil {
        label.truncationToken = truncationToken
        return truncationToken!
    }
    return NSAttributedString()
}

有新的进展么？
