如何在iOS App中集成PayPal / Apple Pay付款模塊？

Question

我正在研究如何在iOS App中集成PayPal / Apple Pay付款模塊。

例如，在我的應用程序中，我想集成PayPal / Apple Pay付款，那我該怎么辦？ 有什么過程。

如果任何人都可以指導如何做。 請給我建議步驟。 任何參考鏈接，然后也歡迎。

Answer 1

這取決於您集成的付款解決方案。 貝寶將支持帳戶余額或與帳戶關聯的信用卡/借記卡/銀行的資金來源。 與PayPal錢包不同的是，Apple Pay / Apple Wallet中沒有“余額”事物，它僅與卡令牌化（您在Wallet App中設置的卡）一起使用。

在這種情況下，您的應用程序不一定要檢查錢包中是否有20美元（PayPal或Apple Pay），而是會啟動付款請求，並從付款網關獲取響應以處理您的訂單

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;
}

與您的控制器

在您的.h文件集委托中

@interface MyCart：UITableViewController

@property（非原子，強，可讀寫）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;


}

購買按鈕事件代碼

-(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);
}
