推荐答案
您将两种不同的东西结合在一起.您可以要么将属性应用于字符串或读取一些HTML.两者都不是.
You are combining two different things. You can either apply an attribute to a string or read some HTML. Not both.
也许你的意思是:
let myAttribute = [ NSAttributedStringKey.font: UIFont(name: "Chalkduster", size: 18.0)! ]
let attrStr = NSAttributedString(string: "howdy there", attributes: myAttribute)
或者你的意思是:
let html = "<p>howdy <b>there</b></p>"
let htmldata = html.data(using: .utf8)
let attrStr = try NSAttributedString(data: htmldata!, options: [.documentType : NSAttributedString.DocumentType.html], documentAttributes: nil)
下定决心.
