一、在Apple开发者中心配置 AppleID 和 Merchant IDs
二、配置好证书后在Xcode中开启Apple Pay
三、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。
// 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
// 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
// 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
-(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];
}四、如图为最终的实现方法，商品信息根据实际设置，配送信息等根据实际商品来选择，如果是虚拟商品则不需要
