，我想为单选按钮分配一个值 radioUSD = 0.395 radioEUR = 0.447

ViewController类：NSViewController {

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view.
}


@IBOutlet weak var radioUSD: NSButton!
@IBOutlet weak var radioEUR: NSButton!
@IBOutlet weak var Label: NSTextField!
@IBOutlet weak var value: NSTextField!

var us = 0.395
var eur = 0.447

@IBAction func calc(_ sender: Any) {
    Label.doubleValue = value.doubleValue * us
}

override var representedObject: Any? {
    didSet {
    // Update the view, if already loaded.
    }
}

}

如果我选择，我希望输出是美元值* 0.395 对于我们的值* 0.447
