For example in my app i want to integrate PayPal/Apple pay for payment, then what should I do ? What are the process.

如果任何人都可以指导如何去做。请建议我的步骤。任何参考link然后也欢迎。

Answer 1

这取决于您集成的支付解决方案。 PayPal 将支持与账户关联的账户余额或信用 card/debit card/bank 的资金来源。虽然与 PayPal 钱包不同，Apple Pay/Apple 钱包中没有 "balance" 东西，它纯粹与卡令牌化（您在钱包应用程序中设置的卡）一起工作。

在此用例中，您的应用不一定会检查钱包中是否有 20 美元（PayPal 或 Apple Pay），而是会发起支付请求，并从支付网关获取响应以处理您的订单

在 AppDelegate 中

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    [PayPalMobile initializeWithClientIdsForEnvironments:@{PayPalEnvironmentProduction : @"YOUR_CLIENT_ID_FOR_PRODUCTION",
                                                           PayPalEnvironmentSandbox : @"AeB0tbkw-z4Ys3NvxekUZxnVNk26WXRodQBETFG4x-HtQAuqBf5k4edWOn2zia_l8RWBFJGEUNSVWJWg"}];

    return YES;
}

使用控制器

在你的 .h 文件中设置委托

@interface MyCart : UITableViewController

@属性（非原子，强，读写）PayPalConfiguration *payPalConfig;

在您的 .m 文件中

- (void)viewDidLoad {
 NSString *environment=@"sandbox";
    self.environment = environment;
    [PayPalMobile preconnectWithEnvironment:environment];


 _payPalConfig = [[PayPalConfiguration alloc] init];
    _payPalConfig.acceptCreditCards = YES;
    _payPalConfig.merchantName = @"ScanPay";
    _payPalConfig.merchantPrivacyPolicyURL = [NSURL URLWithString:@"https://www.paypal.com/webapps/mpp/ua/privacy-full"];
    _payPalConfig.merchantUserAgreementURL = [NSURL URLWithString:@"https://www.paypal.com/webapps/mpp/ua/useragreement-full"];

    _payPalConfig.languageOrLocale = [NSLocale preferredLanguages][0];

    _payPalConfig.payPalShippingAddressOption = PayPalShippingAddressOptionPayPal;


}

带有购买按钮事件的代码

-(IBAction)btnCheckoutTapped
{
//    UIAlertView *alt=[[UIAlertView alloc]initWithTitle:@"ScanPay" message:@"Under Development" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
//    [alt show];

    NSDecimalNumber *subtotal = [[NSDecimalNumber alloc]initWithDouble:Price];

    // Optional: include payment details
    NSDecimalNumber *shipping = [[NSDecimalNumber alloc] initWithString:@"0.00"];
    NSDecimalNumber *tax = [[NSDecimalNumber alloc] initWithString:@"0.00"];
    PayPalPaymentDetails *paymentDetails = [PayPalPaymentDetails paymentDetailsWithSubtotal:subtotal
                                                                               withShipping:shipping
                                                                                    withTax:tax];
    NSDecimalNumber *total = [[subtotal decimalNumberByAdding:shipping] decimalNumberByAdding:tax];

    PayPalPayment *payment = [[PayPalPayment alloc] init];
    payment.amount = total;
    payment.currencyCode = @"USD";
    payment.shortDescription = @"You Pay";
    payment.paymentDetails = paymentDetails; // if not including payment details, then leave payment.paymentDetails as nil
    if (!payment.processable) {
        // This particular payment will always be processable. If, for
        // example, the amount was negative or the shortDescription was
        // empty, this payment wouldn't be processable, and you'd want
        // to handle that here.
    }
    // Update payPalConfig re accepting credit cards.
    self.payPalConfig.acceptCreditCards = YES;

    PayPalPaymentViewController *paymentViewController = [[PayPalPaymentViewController alloc] initWithPayment:payment
                                                                                                configuration:self.payPalConfig
                                                                                                     delegate:self];
    [self presentViewController:paymentViewController animated:YES completion:nil];


}

PayPalPaymentDelegate 方法

- (void)payPalPaymentViewController:(PayPalPaymentViewController *)paymentViewController didCompletePayment:(PayPalPayment *)completedPayment {
    NSLog(@"PayPal Payment Success!");
    [self ErrorWithString:@"PayPal Payment Success!"];



    self.resultText = [completedPayment description];
    //[self showSuccess];

    [self sendCompletedPaymentToServer:completedPayment]; // Payment was processed successfully; send to server for verification and fulfillment
    [self dismissViewControllerAnimated:YES completion:nil];

    ReceiptScreen *obj=[self.storyboard instantiateViewControllerWithIdentifier:@"ReceiptScreen"];
    [self.navigationController pushViewController:obj animated:YES];

}

- (void)payPalPaymentDidCancel:(PayPalPaymentViewController *)paymentViewController {
    NSLog(@"PayPal Payment Canceled");
    self.resultText = nil;
  //  self.successView.hidden = YES;
    [self dismissViewControllerAnimated:YES completion:nil];
}

#pragma mark Proof of payment validation

- (void)sendCompletedPaymentToServer:(PayPalPayment *)completedPayment {
    // TODO: Send completedPayment.confirmation to server
    NSLog(@"Here is your proof of payment:\n\n%@\n\nSend this to your server for confirmation and fulfillment.", completedPayment.confirmation);
}
