我試圖使用Fabric設置Stripe，我的第一步當然是接受來自用戶的信用卡信息。通過下面的代碼，提交按鈕變爲啓用時，但應用程序崩潰時，單擊按鈕。錯誤消息是「終止應用程序由於未捕獲的異常'NSInvalidArgumentException'，原因：' - [Stripe3.ViewController submitCard：]：無法識別的選擇器發送到實例0x7fe83740dbd0'」Stripe Fabric iOS集成
我將不勝感激任何見解！
class ViewController: UIViewController, STPPaymentCardTextFieldDelegate{
var paymentTextField: STPPaymentCardTextField! = nil
var submitButton: UIButton! = nil
override func viewDidLoad() {
super.viewDidLoad()
paymentTextField = STPPaymentCardTextField(frame: CGRectMake(15, 30, view.frame.width - 30, 44))
paymentTextField.delegate = self
view.addSubview(paymentTextField)
submitButton = UIButton(type: UIButtonType.system)
submitButton.frame = CGRectMake(15, 100, 100, 44)
submitButton.isEnabled = false
submitButton.setTitle("Submit", for: UIControlState.normal)
submitButton.addTarget(self, action: Selector(("submitCard:")), for: UIControlEvents.touchUpInside)
view.addSubview(submitButton)
// Do any additional setup after loading the view, typically from a nib.
}
func paymentCardTextFieldDidChange(_ textField: STPPaymentCardTextField) {
submitButton.isEnabled = textField.valid
}
@IBAction func submitCard(sender: AnyObject?) {
// If you have your own form for getting credit card information, you can construct
// your own STPCardParams from number, month, year, and CVV.
let card = paymentTextField.card!
STPAPIClient.shared().createToken(withCard: card) { token, error in
guard let stripeToken = token else {
NSLog("Error creating token: %@", error!.localizedDescription);
return
}
// TODO: send the token to your server so it can create a charge
let alert = UIAlertController(title: "Welcome to Stripe", message: "Token created: \(stripeToken)", preferredStyle: .alert)
alert.addAction(UIAlertAction(title: "OK", style: .default, handler: nil))
self.present(alert, animated: true, completion: nil)
}
