如何使属性字符串永不换行？

问：

我正在将 NSAttributedString 用于我的 NSTextView，以显示超链接以及其他一些字符串。当我的另一个字符串很长时，链接字符串会换行（即链接字符串会断开并移动到下一行）。如何避免它。

我将提供我所做工作的示例代码：

            let displayedStringValue ="Learn More"
            let url = URL(string: displayedStringValue)
            let linkRange = NSRange(location: detail.count, length: displayedStringValue.count)
            let fullTextString = "This is sample String" + displayedStringValue
            let attributedString = NSMutableAttributedString(string: fullTextString)
            let learnMoreFontColor = NSColor.Red
            let linkAttributes: [NSAttributedString.Key: Any] = [
                .foregroundColor: learnMoreFontColor,
            ]
            attributedString.addAttributes(linkAttributes, range: linkRange)
            attributedString.addAttribute(.link, value: url, range: linkRange)
            
            let font = NSFont.systemFont(ofSize: 14.0)

            let contentFontColor = NSColor.Red
            let range = NSRange(location: 0, length: attributedString.length)
            attributedString.addAttribute(.font, value: font, range: range)
            let contentRange = NSRange(location: 0, length: detail.length)
            attributedString.addAttribute(.foregroundColor, value: contentFontColor, range: contentRange)
            myTextField.linkTextAttributes = linkAttributes
            myTextField.textStorage?.setAttributedString(attributedString)

当 detailsstring 的内容较长时，了解更多字符串正在剪裁。如何避免这种情况？
