In Swift 3 its much simpler. add an html doc to your root dir and post whatever script you want in it then use a webview with...

let url = Bundle.main.url(forResource: "logo", withExtension: "html")
let request = NSURLRequest(url: url!)
webView.loadRequest(request as URLRequest)

This is how you should go about it unless you need to reference app vars or data from the phone that js normally wouldn't access

Hi, i'm trying to inject two NSUserdefaults into Username and a password field of a website in a webview. How can i do that?
The fields:

input class= "input" type="text" size="10" maxlenght="50" name="frmLoginMemberID" value=""

input class= "input" type="password" size="10" maxlenght="50" name="frmLogin2" value=""

username.text = [[NSUserDefaults standardUserDefaults] objectForKey:@"usernamekey"];
password.text = [[NSUserDefaults standardUserDefaults] objectForKey:@"passwordkey"];

if I wanted to save the javascript as a string directly, what do I do?
