当我尝试用card.IO扫描一张卡时。它不会打开相机，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。有什么想法吗？样品在obj-C的io8中工作良好。
@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!) {
}
plist文件中是否有需要修改的地方，以便允许iOS8的摄像机访问？
最佳答案
解决方案如下：https://github.com/card-io/card.io-iOS-SDK/issues/76#issuecomment-65856792
即：
您没有正确初始化CardIOPaymentViewController。应该是
var CardScanner:CardIOPaymentViewController=CardIOPaymentViewController（paymentDelegate:self）
