如何将本地HTML加载到UIWebView

Question

I am able to load up an external URL in a UIWebView like so:

let url = NSURL(string: "http://www.google.com")
let request = NSURLRequest(URL: url)
webView.loadRequest(request)

but how do I load a local html file?

The answer in this solution looked promising but Xcode says NSString.stringWithContentsOfFile() is deprecated.

Answer 1

You can do essentially what you're doing now, just use NSBundle to get a URL for your local file, like this:

if let url = NSBundle.mainBundle().URLForResource("index", withExtension: "html") {
    webView.loadRequest(NSURLRequest(URL: url))
}

Thanks @Nate Cook. Here is the update to Swift 3

    if let url = Bundle.main.url(forResource: "about", withExtension: "html") {
        webView.loadRequest(NSURLRequest(url: url) as URLRequest)
    }
