问题描述

我有一段包含自定义<link>标签的文本，格式示例如下：

"My firstand second"

我编写了一个Swift函数，接收存储完整<link>标签（含href属性和内部文本）的字符串数组，目标是给标签内的文本添加下划线、指定颜色，同时实现链接跳转功能。函数代码如下：

private func setUrlAndStyleToEachLinkText(arrayOfLinks: [String], font: UIFont){
    for link in arrayOfLinks {
        var linkAsNSString = link as NSString
        if (hasHref(linkString: linkAsNSString)) {
            // Cleaning whitespaces
            linkAsNSString = linkAsNSString.replacingOccurrences(of: " ", with: "") as NSString
            let closedOpenTagPosition = linkAsNSString.range(of: "'&gt;", options: String.CompareOptions.literal)
            let hrefPosition = linkAsNSString.range(of: "href='")
            // Obtaining url from href
            hrefUrl = linkAsNSString.substring(with: NSUnionRange(NSRange(location: hrefPosition.location + hrefPosition.length, length: 0),
                                                                      NSRange(location: closedOpenTagPosition.location, length: 0)))
            // Obtaining link text to apply tap gesture
            let linkText = linkAsNSString.substring(with: NSUnionRange(NSRange(location: closedOpenTagPosition.location + closedOpenTagPosition.length, length: 0),
                                                                       NSRange(location: link.count - 8, length: 0)))
            
            let attributes: [NSAttributedString.Key:Any] = [
                NSAttributedString.Key.font: font,
                NSAttributedString.Key.underlineStyle: NSUnderlineStyle.single.rawValue,
                NSAttributedString.Key.underlineColor: self.underlineColor,
                NSAttributedString.Key.link: hrefUrl
            ]
            let attributedString = NSMutableAttributedString(string: linkText, attributes: attributes)
        }
    }
}

但设置后，文本的样式属性并未显示，求助解决方法。

已解决

问题原因是未将创建好的富文本属性应用到正确的变量（比如显示用的UILabel/UITextView的attributedText），感谢@Larme的评论提示。
