Display local HTML page in UIWebView

Question

I want to show a local HTML file in my UIWebView. I can show it, but without any styles or images. Means relative paths are not working but I must use relative paths because there will be much more files. Here is my WebViewController:

class WebViewController: UIViewController {
    @IBOutlet weak var web1: UIWebView!

    var fileName : String!

    override func viewDidLoad() {
        if let file = self.fileName{
            print("got: "+file)
        }

        let url = NSBundle.mainBundle().URLForResource(self.fileName, withExtension:"html")
        let request = NSURLRequest(URL: url!)
        web1.loadRequest(request)

        //this does not work, webview gets blank (white)
//        let path: String? = NSBundle.mainBundle().pathForResource("AceVetBolus", ofType: "html", inDirectory: "HTMLFiles")
//        if let unwrappedPath = path {
//            let requestURL = NSURL(string: unwrappedPath)
//            let request = NSURLRequest(URL: requestURL!)
//            
//            web1.loadRequest(request)
//        }
    }
}

Here is my folder structure:

Here is my html:

<!DOCTYPE html>
<html lang="en-US">
<meta name="viewport" content="width=device-width, initial-scale=1">
<head>

<link rel="stylesheet" type="text/css" href="./css/product.css" />

</head>
<body>

<p> Each Bolus contains Paracetamol BP 2000 mg. </p>

your problem is that on the app's bundle, there are no folders image or css, you just copied the files, without the folder structure

Try this:

Click on HTML Files group and press delete, select Remove references
Go to the Finder folder HTML Files and drag the entire folder to
the project, select Create folde references
A blue folder should appear on your project
If you check your target under Build Phases>Copy Bundle Resources, you'll see that the entire folder structure is now added to your bundle

You need not identify the folder ./css/,./images/ directly use file name i.e product.css and chicken_icon.png.

Just try following HTML.

<!DOCTYPE html>
<html lang="en-US">
<meta name="viewport" content="width=device-width, initial-scale=1">
<head>

<link rel="stylesheet" type="text/css" href="product.css" />

</head>
<body>

EDITED

Remove HTML Root folder reference.
Drag your html folder into your project.
Follow image

Now use your code.

    override func viewDidLoad() {
            super.viewDidLoad()
            // Do any additional setup after loading the view, typically from a nib.
           if let file = self.fileName{
            print("got: "+file)
        }

        let url = NSBundle.mainBundle().URLForResource(self.fileName, withExtension:"html")
        let request = NSURLRequest(URL: url!)
        web1.loadRequest(request)
}

For that you need to insert physical file into bundle not `references`. — Nimit Parekh, Dec 01 '15 at 10:58
