Autofill Username and Password UIWebView Swift

Question

I\'ve found many ways to autofill a username and password in objective-c, but I can\'t figure out how to make it work with Swift. What would be the Swift equivalent of this

Answer 1

Here is a simple swift conversion of your provided code. SStringByEvaluatingJavaScriptFromString has been tested using different javascript and works correctly.

func webViewDidFinishLoad(webView: UIWebView!) {

    let savedUsername = NSUserDefaults.standardUserDefaults().stringForKey("USERNAME")
    let savedPassword = NSUserDefaults.standardUserDefaults().stringForKey("PASSWORD")

    if savedUsername == nil || savedPassword == nil {return}

    if ( countElements(savedUsername!) != 0 && countElements(savedPassword!) != 0) {
        let loadUsernameJS = "var inputFields = document.querySelectorAll(\"input[name='username']\"); \\ for (var i = inputFields.length >>> 0; i--;) { inputFields[i].value = \'\(savedUsername)\';}"
        let loadPasswordJS = "var inputFields = document.querySelectorAll(\"input[name='password']\"); \\ for (var i = inputFields.length >>> 0; i--;) { inputFields[i].value = \'\(savedPassword)\';}"

        self.webview.stringByEvaluatingJavaScriptFromString(loadUsernameJS)
        self.webview.stringByEvaluatingJavaScriptFromString(loadPasswordJS)
    }
}
