Question

我想在iOS应用中显示以下html文字

<p><span style="color: #000000;">Experience royalty in all its splendor</span><br /><span style="color: #000000;"> An address that is a possession of pride</span></p>

我尝试使用NSAttributedString并在html字符串中添加字体，但无效

let st:String = pjt.value(forKey: "description") as! String // Original content from API - "&lt;p&gt;&lt;span style=&quot;color: #000000;&quot;&gt;Experience royalty in all its splendor&lt;/span&gt;&lt;br /&gt;&lt;span style=&quot;color: #000000;&quot;&gt; An address that is a possession of pride&lt;/span&gt;&lt;/p&gt;&lt;........"

let desc:Data = st.data(using: String.Encoding.utf8, allowLossyConversion: true)!
                //st.data(using: String.Encoding.utf16)!
            do {
                let attrStr = try NSAttributedString(data: desc, options: [NSDocumentTypeDocumentAttribute:NSHTMLTextDocumentType], documentAttributes: nil)
                print("Attr STr \(attrStr)")
                self.textView.attributedText = attrStr;
            }

它也无法在self.webView.loadHTMLString(st, baseURL: nil)

的网络视图中使用

更新

Textview或webview或label all显示相同的普通html字符串Experience royalty in all its splendor An address that is a possession of pride

有任何帮助吗？

注意：Swift 3

谢谢！

你的字符串是

"&lt;p&gt;&lt;span style=&quot;color: #000000;&quot;&gt;Experience royalty in all its splendor&lt;/span&gt;&lt;br /&gt;&lt;span style=&quot;color: #000000;&quot;&gt; An address that is a possession of pride&lt;/span&gt;&lt;/p&gt;"

将所有HTML标记编码为HTML实体。该字符串必须转换为

<p><span style="color: #000000;">Experience royalty in all its splendor</span><br /><span style="color: #000000;"> An address that is a possession of pride</span></p>

之前

将其传递给属性字符串。例如，这可以使用How do I decode HTML entities in swift?中的stringByDecodingHTMLEntities方法完成：

let st = (pjt.value(forKey: "description") as! String).stringByDecodingHTMLEntities

（与您当前的问题无关：强制演员as! String 如果值不存在或者不是字符串，则可能在运行时崩溃。您应该使用可选绑定。）
