swift - 使用 Card.IO 使用相机 IOS8 / Swift 时遇到问题

Question

当我尝试使用 Card.IO 扫描卡时。它不会调出相机，更不用说它周围的绿线了。当我运行此代码并按下按钮时，它不会在视图控制器中显示相机。有任何想法吗 ？该示例在 obj-C 的 io8 中运行良好。

@IBAction func PressScan(sender: AnyObject) {

    var CardScanner : CardIOPaymentViewController = CardIOPaymentViewController()
    CardScanner.modalPresentationStyle = UIModalPresentationStyle.FullScreen
    self.presentViewController(CardScanner, animated: true, completion: nil)




}
override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
    CardIOPaymentViewController.preload()
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

func userDidProvideCreditCardInfo(cardInfo: CardIOCreditCardInfo!, inPaymentViewController paymentViewController: CardIOPaymentViewController!) {

}

func userDidCancelPaymentViewController(paymentViewController: CardIOPaymentViewController!) {

}

我需要修改 plist 文件中的某些内容以允许 iOS8 的相机访问吗？

即：

您没有正确初始化 CardIOPaymentViewController。它应该是

var CardScanner : CardIOPaymentViewController = CardIOPaymentViewController(paymentDelegate: self)
