Question

我做了很多搜索，无法找出在UITextView中添加html内容的正确方法。以下是我的代码。没有设置正确的字体类型。

let htmlProfileString = "<html><head><style>body {font-family:\"SFProText-Regular\";font-size: 16px;color: #FFFFFF;text-decoration:none;}</style></head><body>" +
                        "This is content"
                        + "</body></head></html>"

                    let htmlData = NSString(string: htmlProfileString).data(using: String.Encoding.unicode.rawValue)

                    let options = [NSAttributedString.DocumentReadingOptionKey.documentType: NSAttributedString.DocumentType.html]

                    let attributedString = try! NSAttributedString(data: htmlData!, options: options, documentAttributes: nil)
                    self.textView.attributedText = attributedString

Answer 1

如果您不希望textView可编辑，则将其替换为webView。

如果这样做，则可以使用以下方法将html加载到webView中：

func loadHTMLString(_ string: String, 
        baseURL: URL?)

Answer 2

要使用“系统”旧金山字体，请使用-apple-system：

    let htmlProfileString = "<html><head><style>body {font-family:\"-apple-system\";font-size: 16px;color: #FFFFFF;text-decoration:none;}</style></head><body>" +
        "This is content"
        + "</body></head></html>"

您还可以将其他CSS字体样式用于：

font: -apple-system-body 
font: -apple-system-headline 
font: -apple-system-subheadline 
font: -apple-system-caption1 
font: -apple-system-caption2 
font: -apple-system-footnote 
font: -apple-system-short-body 
font: -apple-system-short-headline 
font: -apple-system-short-subheadline 
font: -apple-system-short-caption1 
font: -apple-system-short-footnote 
font: -apple-system-tall-body
