(这是一个截图，以防我的链接不可用):

如果我不能，我如何使用 Swift 用我的变量填写这个表格？

现在我使用下面的缓解代码:WV1.stringByEvaluatingJavaScriptFromString("document.getElementById('username')‌​.value = '" + RA + "'") WV1.stringByEvaluatingJavaScriptFromString("document.getElementById('passwd').v‌​alue = '" + CPF + "'") WV1.stringByEvaluatingJavaScriptFromString("document.getElementById('btnlogin')‌​.click()")

您必须检测其余的完整参数才能登录此 joomla 门户:

例如:

POST 方法: http://webgiz.faqserv.com/webgiz/index.php?option=com_aixgen&username=test&password=test&userType=A&instituicao=0

@IBOutlet weak var usernameTextField: UITextField!
// `passwordTextField.secureTextEntry = true`
@IBOutlet weak var passwordTextField: UITextField!
@IBOutlet weak var webView: UIWebView!

...

@IBAction func signIn(sender: AnyObject) {
    var url = NSURL(string: "http://webgiz.faqserv.com/webgiz/index.php")
    var request = NSMutableURLRequest(URL: url!)
    request.HTTPMethod = "POST"

    // Get the user's credentials from the `UITextField`s
    var username: String = usernameTextField.text
    var password: String = passwordTextField.text

    // Concatenating everything together
    var userCredentials: String = "username=\(username)&passwd=\(password)&userType=A&instituicao=0" // add all parameters needed
    var bodyData: String = "\(userCredentials)"

    // Encode the bodyData string into a 
    request.HTTPBody = bodyData.dataUsingEncoding(NSUTF8StringEncoding)

    // load the UIWebView `webView` with this request
    webView.loadRequest(request)
}
