NSAttributedString: Fit image to container

Question

I have a NSAttributedString which is made from HTML and it displays some images. The problem is that the images are bigger than the container and I wonder how to fit them in

Answer 1

Swift 4.2 : Using the approach of @Nic Hubbard

let htmlString = "Put Your YourHTML String Here"

let setHeightUsingCSS = "  \(htmlString) "

self.textView.attributedText = setHeightUsingCSS.html2AttributedString


extension Data {
    var html2AttributedString: NSAttributedString? {
        do {
            return try NSAttributedString(data: self, options: [.documentType: NSAttributedString.DocumentType.html, .characterEncoding: String.Encoding.utf8.rawValue], documentAttributes: nil)
        } catch {
            print("error:", error)
            return  nil
        }
    }
    var html2String: String {
        return html2AttributedString?.string ?? ""
    }
}

extension String {
    var html2AttributedString: NSAttributedString? {
        return Data(utf8).html2AttributedString
    }
    var html2String: String {
        return html2AttributedString?.string ?? ""
    }
}
