Question

let rect = CGRectMake(0, 20, 320, 460)
    let webView = UIWebView(frame: rect)

    let url = NSURL(string: "https://www.apple.com”)
    let request = NSURLRequest(URL: url!)

    webView.loadRequest(request)
    self.view.addSubview(webView)

导入UIKit

class ImportSkattViewController: UIViewController {

    @IBOutlet weak var textfield: UITextField!
    @IBOutlet weak var svar: UILabel!
    override func viewDidLoad() {
        super.viewDidLoad()
        textfield.keyboardType = UIKeyboardType.DecimalPad

        let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: "dismissKeyboard")
        view.addGestureRecognizer(tap)

        // Do any additional setup after loading the view.
    }

    func dismissKeyboard() {
        //Causes the view (or one of its embedded text fields) to resign the first responder status.
        view.endEditing(true)

        if textfield.text == ""{
        }
        else{
            let nf = NSNumberFormatter()

            let atext2 = nf.numberFromString(textfield.text!)
            let skatt = 1.25
            let CurencyValue = 0

            let result = Float(atext2!) * Float(skatt) * Float(CurencyValue)
            svar.text = ("\(result)")

        }






    }

Answer 1

问题是你（很可能）不能使用你给的网站。我不会说/读瑞典语（根据.se网站^^)，所以也许他们说他们在某个地方有API。

无论如何，您必须使用API才能获得可用格式（例如JSON）的响应。如果您调用给定的网站，您将得到一个HTML响应，并不真正容易提取有用的数据（在您的情况下）。

fixer.io看起来使用起来非常简单，它只是给出了费率，但是通过简单的计算就可以很容易地转换任何金额。
