objective c-在iOS上使用Stripe验证信用卡

(objective c - Validating credit cards using Stripe with iOS)

发布于 2015-10-15 00:28:56

我开始将Stripe集成到我正在制作的iOS应用程序中，现在我需要验证卡信息。

我试过：

#pragma mark - My Actions

- (IBAction)buyButtonTapped:(id)sender {

  //Populate STPCard property
  self.stripeCard = [[STPCard alloc]init];
  self.stripeCard.name = self.txtFieldCardHolderName.text;
  self.stripeCard.number = self.txtFieldCardNumber.text;
  self.stripeCard.cvc = self.txtFieldCardCvc.text;
  self.stripeCard.expMonth = [self.selectedMonth integerValue];
  self.stripeCard.expYear = [self.selectedYear integerValue];

  //Validate Customer info
  if ([self validateCustomerInfo]) {
    [self performStripeOperation];
  }

} 

-(BOOL)validateCustomerInfo{

  //Create Alert

  UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Please, try again!"
                                                                 message:@"Please, enter all required information."
                                                          preferredStyle:UIAlertControllerStyleAlert];

  UIAlertAction *action = [UIAlertAction actionWithTitle:@"OK"
                                                   style:UIAlertActionStyleDefault
                                                 handler:^(UIAlertAction * _Nonnull action) {

                                                   //Add some action

                                                 }];

  //Add its action
  [alert addAction:action];


  //Validate text fields
  if (self.txtFieldCardHolderName.text == 0 || self.txtFieldCardNumber.text == 0 || self.txtFieldCardExpDate.text == 0 || self.txtFieldCardCvc.text == 0) {

    [self presentViewController:alert animated:true completion:nil];
    return NO;
  }

  //Validate card number, CVC, expMonth, expYear
  NSError *error = nil;

  [self.stripeCard validateCardReturningError:&error];

  //3
  if (error) {
    alert.message = [error localizedDescription];
    [self presentViewController:alert animated:true completion:nil];
    return NO;
  }

  return YES;

}

我在StackOverflow上检查了其他几个问题，每个人似乎都使用validateCardReturningErrormethod，iOS9已弃用该方法。

Xcode抱怨并要求我改用STPCardValidator。

有人可以帮我举一个使用STPCardValidator进行卡验证的示例吗？

我注意到我也可以使用以下Class方法：

[STPCardValidator validationStateForNumber:self.txtFieldCardNumber.text validatingCardBrand:true];

但是我不确定如何在我的validateCustomerInfo方法中使用它。

是的，我们可以检查卡是否为信用卡，但可以对其进行自定义类，如果我们使用的是stp，则它们为我们提供了验证方法，我们只需要实现它即可

Ashok 2017-09-19 09:01:03

@FeminaBrahmbhatt，您能否提供代码级别准则以检查卡是借记卡还是信用卡？

Ashok 2017-09-19 09:01:20

@AbidHussain您是否找到任何方法来检查卡是借记卡还是信用卡？
