2.18日 Apple Pay正式登陆中国了，18号就开始绑定绑定卡片，上午坑次坑次的开始试，试了N多次都不行，可能是因为是苹果的Pay，大家都这么激动，CocoaChina 第一时间体验Apple Pay，能秒微信、支付宝？
首先，准备工作，在开发者中心建Merchant IDs 和Apple Pay证书。Merchant IDs的ID在代码中还是会用到的，建议域名的反向解析。
Apple Pay证书新建的时候要注意：创建一个CSR文件（在Mac上的应用程序文件夹，打开Utilities文件夹并启动钥匙串访问。在钥匙串访问下拉菜单中选择钥匙串访问>证书助理>请求从证书颁发机构颁发的证书。）
勾选上让我指定密钥对信息
苹果上规定是用ECC算法大小256位
生成CSR文件，然后上传，成功后，下载，双击。
如果KeyChain Access中显示了警示信息，表示未知授权签发证书或者无效证书发行人，那么要确保你已经在钥匙链中安装了Worldwide Developer Relations-G2和Apple Root CA-G2。你可以在这个地方下载这些东西：apple.com/certificateauthority.
证书
Xcode里边的设置
Xcode的设置，Gapabilities-->Apple Pay变成 ON，勾选Merchant IDs的ID，还要导入PassKit包
PassKit
基本的配置也就这么多了，好了，下边是代码时间，Objective-C与Swift：
Objective-C:
#import <PassKit/Passkit.h>和PKPaymentAuthorizationViewControllerDelegate
//是否支持ApplePay系统版本，硬件ParentControl或者是否因为家长控制而不能支付
BOOLisSupportPay = [PKPaymentAuthorizationViewControllercanMakePayments];
if(!isSupportPay) {
return;
}else{
// do something
}
//是否支持这些支持方式（可能没有绑定卡）判断用户是否能够使用你提供的支付网络进行支付
NSArray*netwotks =@[PKPaymentNetworkPrivateLabel,PKPaymentNetworkVisa,PKPaymentNetworkMasterCard];
BOOLcanPay = [PKPaymentAuthorizationViewControllercanMakePaymentsUsingNetworks:netwotks];
if(!canPay) {
//setup
PKPaymentButton*setupButton = [PKPaymentButtonbuttonWithType:PKPaymentButtonTypeSetUpstyle:PKPaymentButtonStyleBlack];
[setupButtonaddTarget:selfaction:@selector(applePaySetupButtonPressed:)forControlEvents:UIControlEventTouchUpInside];
[self.viewaddSubview:setupButton];
setupButton.center=CGPointMake(self.view.frame.size.width/2,100);
}else{
//发起支付请求
//PKPaymentRequest
PKPaymentRequest*paymentRequest = [PKPaymentRequestnew];
paymentRequest.currencyCode=@"CNY";
paymentRequest.countryCode=@"CN";
paymentRequest.merchantIdentifier=@"merchant.com.hunk.assistants";
//构造金额
// 2.01 subtotal标签文本是一个用户可阅读的摘要项目描述信息，数额是相对应的支付数额
NSDecimalNumber*subtotalAmount = [NSDecimalNumberdecimalNumberWithMantissa:201exponent:-2isNegative:NO];
PKPaymentSummaryItem*subtotal = [PKPaymentSummaryItemsummaryItemWithLabel:@"Subtotal"amount:subtotalAmount];
// 2.00 discount对于折扣或优惠券，则需要把数额设成负数。
NSDecimalNumber*discountAmount = [NSDecimalNumberdecimalNumberWithMantissa:200exponent:-2isNegative:YES];
PKPaymentSummaryItem*discount = [PKPaymentSummaryItemsummaryItemWithLabel:@"Discount"amount:discountAmount];
// 0.01 grand total总计金额应该使用公司的名称做为其标签，使用所有其它项目的金额总和做为金额
NSDecimalNumber*totalAmount = [NSDecimalNumberzero];
totalAmount = [totalAmountdecimalNumberByAdding:subtotalAmount];
totalAmount = [totalAmountdecimalNumberByAdding:discountAmount];
PKPaymentSummaryItem*total = [PKPaymentSummaryItemsummaryItemWithLabel:@"Gou Min Company"amount:totalAmount];
NSArray*summaryItems =@[subtotal, discount, total];
paymentRequest.paymentSummaryItems= summaryItems;
// Shipping Method (skip now)
//支付标准
paymentRequest.supportedNetworks=@[PKPaymentNetworkPrivateLabel,PKPaymentNetworkMasterCard,PKPaymentNetworkVisa];
// Supports 3DS only还可以设置支持其他的
paymentRequest.merchantCapabilities=PKMerchantCapability3DS;
//配送信息以及mail地址
paymentRequest.requiredBillingAddressFields=PKAddressFieldEmail;
paymentRequest.requiredBillingAddressFields=PKAddressFieldEmail|PKAddressFieldPostalAddress;
PKContact*contact = [[PKContactalloc]init];
NSPersonNameComponents*name = [[NSPersonNameComponentsalloc]init];
name.givenName=@"John";
name.familyName=@"Appleseed";
contact.name= name;
CNMutablePostalAddress*address = [[CNMutablePostalAddressalloc]init];
address.street=@"1234 Laurel Street";
address.city=@"Atlanta";
address.state=@"GA";
address.postalCode=@"30303";
contact.postalAddress= address;
paymentRequest.shippingContact= contact;
// Storing Additional Information
// request.applicationData =
// Authorizing Payment show
PKPaymentAuthorizationViewController*viewController = [[PKPaymentAuthorizationViewControlleralloc]initWithPaymentRequest:paymentRequest];
if(!viewController) {
/* ... Handle error ... */
}else{
viewController.delegate =self;
[selfpresentViewController:viewController animated:YEScompletion:nil];
}
}
Swift:
import passkit 和PKPaymentAuthorizationViewControllerDelegate
//
letisSupportPay:Bool=PKPaymentAuthorizationViewController.canMakePayments()
if!isSupportPay {
return;
}else{
//do something
}
letnetWork:Array= [PKPaymentNetworkPrivateLabel,PKPaymentNetworkVisa,PKPaymentNetworkMasterCard]
letcanPay:Bool=PKPaymentAuthorizationViewController.canMakePaymentsUsingNetworks(netWork)
if!canPay {
//setup
letsetupButton =PKPaymentButton(type:PKPaymentButtonType.SetUp, style:PKPaymentButtonStyle.Black)
setupButton.addTarget(self, action:"applePaySetupButtonPressed:", forControlEvents:UIControlEvents.TouchUpInside)
self.view.addSubview(setupButton)
setupButton.center=CGPointMake(UIScreen.mainScreen().bounds.width/2,150)
}else{
//PKPaymentRequest
letpaymentRequest =PKPaymentRequest()
paymentRequest.currencyCode="CNY"
paymentRequest.countryCode="CN"
// merchantIdentifier
paymentRequest.merchantIdentifier="merchant.com.hunk.assistants"
paymentRequest.merchantCapabilities= [PKMerchantCapability.Capability3DS,PKMerchantCapability.CapabilityEMV]
paymentRequest.requiredShippingAddressFields=PKAddressField.All
//support Networks
paymentRequest.supportedNetworks= [PKPaymentNetworkVisa,PKPaymentNetworkMasterCard,PKPaymentNetworkAmex]
//subtotal
letsubTotal =PKPaymentSummaryItem(label:"Subtotal", amount:NSDecimalNumber(string:"101.00"))
//discount
letdicount =PKPaymentSummaryItem(label:"Discount", amount:NSDecimalNumber(string:"100.00"))
//tax
lettax =PKPaymentSummaryItem(label:"Tax", amount:NSDecimalNumber(string:"2.00"))
paymentRequest.paymentSummaryItems= [subTotal,dicount,tax]
//show the apple pay controller
letpayAuth =PKPaymentAuthorizationViewController(paymentRequest: paymentRequest)
payAuth.delegate=self
self.presentViewController(payAuth, animated:true, completion:nil)
}
代码可以直接复制粘贴，但是配置的还需要亲力亲为。
