swift-ApplePay详细集成

# ApplePayDemo ApplePay详细集成 实现效果：  1.在Apple开发者中心配置 AppleID 和 Merchant IDs   2.配置好证书后在Xcode中开启Apple Pay  3.主要代码实现 3.1 判断是否支持Apple Pay，如果支持又将支持哪些银行卡。 ```Objective-C // 判断是否支持Apple Pay if (![PKPaymentAuthorizationViewController canMakePayments]) { NSLog(@"不支持Apple Pay"); // 如果没有绑定VISA或者银联卡，点击按钮去绑定银行卡 }else if (![PKPaymentAuthorizationViewController canMakePaymentsUsingNetworks:@[PKPaymentNetworkVisa,PKPaymentNetworkChinaUnionPay]]){ PKPaymentButton *addPayBtn = [PKPaymentButton buttonWithType:PKPaymentButtonTypeBuy style:PKPaymentButtonStyleWhiteOutline]; [addPayBtn addTarget:self action:@selector(addPay) forControlEvents:UIControlEventTouchUpInside]; addPayBtn.center = self.view.center; [self.view addSubview:addPayBtn]; // 如果存在VISA或者银联卡，点击按钮去支付 }else{ PKPaymentButton *payBtn = [PKPaymentButton buttonWithType:PKPaymentButtonTypeBuy style:PKPaymentButtonStyleBlack]; [payBtn addTarget:self action:@selector(buy) forControlEvents:UIControlEventTouchUpInside]; payBtn.center = self.view.center; [self.view addSubview:payBtn]; } ``` 3.2 如果没有绑定VISA卡或者银联卡时，点击支付按钮会跳转到绑卡页面 ```Objective-C // 添加银行卡 -(void)addPay{ PKPassLibrary *pay = [[PKPassLibrary alloc]init]; [pay openPaymentSetup]; } ``` 3.3 如果已经绑定银行卡，则去支付，并设置支付信息和商户信息 ```Objective-C // 支付 -(void)buy{ // 1.创建支付请求 PKPaymentRequest *request = [[PKPaymentRequest alloc]init]; // 商户号 request.merchantIdentifier = @"merchant.com.zhangdinghao.ApplePay"; // 货币代码和国家代码 request.countryCode = @"CN"; request.currencyCode = @"CNY"; // 请求支付的网络（和之前判断的网络保持一致） request.supportedNetworks = @[PKPaymentNetworkVisa,PKPaymentNetworkChinaUnionPay]; // 商户处理方式 request.merchantCapabilities = PKMerchantCapability3DS; // 商品1 NSDecimalNumber *price = [NSDecimalNumber decimalNumberWithString:@"7999.00"]; PKPaymentSummaryItem *item = [PKPaymentSummaryItem summaryItemWithLabel:@"iPhone 7" amount:price]; // 商品2 NSDecimalNumber *price2 = [NSDecimalNumber decimalNumberWithString:@"149.00"]; PKPaymentSummaryItem *item2 = [PKPaymentSummaryItem summaryItemWithLabel:@"iPhone数据线" amount:price2]; // 商品汇总 NSDecimalNumber *price3 = [NSDecimalNumber decimalNumberWithString:@"8148.00"]; PKPaymentSummaryItem *item3 = [PKPaymentSummaryItem summaryItemWithLabel:@"Apple Store" amount:price3]; request.paymentSummaryItems = @[item,item2,item3]; // 账单或者发票接收地址 request.requiredBillingAddressFields = PKAddressFieldAll; // 快递地址 request.requiredShippingAddressFields = PKAddressFieldAll; NSDecimalNumber *kuaidi = [NSDecimalNumber decimalNumberWithString:@"0.00"]; PKShippingMethod *method = [PKShippingMethod summaryItemWithLabel:@"顺丰" amount:kuaidi]; method.identifier = @"shangmen"; method.detail = @"72小时内送货上门"; request.shippingMethods = @[method]; // 2.验证支付 PKPaymentAuthorizationViewController *avc = [[PKPaymentAuthorizationViewController alloc]initWithPaymentRequest:request]; avc.delegate = self; [self presentViewController:avc animated:YES completion:nil]; } ``` 3.4 实现支付的代理方法 ```Objective-C -(void)paymentAuthorizationViewController:(PKPaymentAuthorizationViewController *)controller didAuthorizePayment:(PKPayment *)payment completion:(void (^)(PKPaymentAuthorizationStatus))completion{ // 拿到支付信息发送给服务器，服务器处理完成后返回支付状态 BOOL isSucess = YES; if (isSucess) { completion(PKPaymentAuthorizationStatusSuccess); }else{ completion(PKPaymentAuthorizationStatusFailure); } } -(void)paymentAuthorizationViewControllerDidFinish:(PKPaymentAuthorizationViewController *)controller{ [self dismissViewControllerAnimated:controller completion:nil]; } ```
