我有一个包含HTML
代码的字符串。显示该图片(包含图片)的最佳方法是什么,我也想在该可点击对象中创建链接(在Safari
中打开)
我尝试过使用NSAttributedString
的{{1}}字符串扩展名,但是图像仅部分显示,并且无法点击链接。
HTML
它向我显示了let text = htmlString.attributedString(withRegularFont: UIFont.systemFont(ofSize: 14), andBoldFont: UIFont.systemFont(ofSize: 16))
extension String {
func attributedString(withRegularFont regularFont: UIFont, andBoldFont boldFont: UIFont, textColor: UIColor = UIColor.gray) -> NSMutableAttributedString {
var attributedString = NSMutableAttributedString()
guard let data = self.data(using: .utf8) else { return NSMutableAttributedString() }
do {
attributedString = try NSMutableAttributedString(data: data,
options: [.documentType: NSAttributedString.DocumentType.html,
.characterEncoding:String.Encoding.utf8.rawValue],
documentAttributes: nil)
let range = NSRange(location: 0, length: attributedString.length)
attributedString.enumerateAttribute(NSAttributedString.Key.font, in: range, options: .longestEffectiveRangeNotRequired) { value, range, _ in
let currentFont: UIFont = value as! UIFont
var replacementFont: UIFont? = nil
if currentFont.fontName.contains("bold") || currentFont.fontName.contains("Semibold") {
replacementFont = boldFont
} else {
replacementFont = regularFont
}
let replacementAttribute = [NSAttributedString.Key.font:replacementFont!, NSAttributedString.Key.foregroundColor: textColor]
attributedString.addAttributes(replacementAttribute, range: range)
} catch let e {
print(e.localizedDescription)
}
return attributedString
}
}
内的HTML
,但是我无法点击链接,并且图像分别根据设备的宽度进行裁剪。
