i can get data from sqlite database in String formate . i have no html file. database and image folder download every time when user login and put in document folder . — Harshil Kotecha, Apr 21 '17 at 05:13
@HarshilKotecha In string format means the URL like `Documents/datadb/DestinationGuide/Images/Destination-Guide.png`, right ? — Nirav D, Apr 21 '17 at 05:16
@HarshilKotecha There is one way if you able to remove `/Documents/` from the image src, Can you done that? Means path only need to be `datadb/DestinationGuide/Images/Destination-Guide.png` — Nirav D, Apr 21 '17 at 05:42

You can save this html at DocumentDirectory as HTML file and then load that file webView. Try something like this way.

let html = "<html><img src=\"datadb/DestinationGuide/Images/Destination-Guide.png\"/> </html>"
//Save this html in `DocumentDirectory`
let saveHTML = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0].appendingPathComponent("sample.html")
try? html.data(using: .utf8)!.write(to: saveHTML)
//Now load this `sample.html` file in webView
webView.loadRequest(URLRequest(url: saveHTML))

i also thinking like this just a minute i test this one :D – Harshil Kotecha Apr 21 '17 at 06:10 — Harshil Kotecha, Apr 21 '17 at 06:10
