如何在iOS App中集成PayPal / Apple Pay支付模块？

Question

我正在研究如何在iOS App中集成PayPal / Apple Pay支付模块。

  

例如在我的应用程序中，我想整合PayPal / Apple支付付款，那么我该怎么办？这是什么过程。

如果有人可以指导如何做到这一点。请建议我的步骤。 任何参考链接也欢迎。

Answer 1

这取决于您集成的付款解决方案。 PayPal将支持与帐户关联的帐户余额或信用卡/借记卡/银行的资金来源。虽然与PayPal钱包不同，Apple Pay / Apple Wallet中没有“平衡”的东西，它完全适用于卡片令牌化（您在电子钱包应用中设置的卡片）。

在此用例中，您的应用无需检查钱包中是否有20美元（PayPal或Apple Pay），而是会发起付款请求，并从付款网关获取响应以处理您的订单

AppDelegate中的

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

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

    return YES;
}

与您的控制器

.h文件集委托

@interface MyCart：UITableViewController

@property（nonatomic，strong，readwrite）PayPalConfiguration * payPalConfig;

.m文件中的

- (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);
}
