Apple Pay强势来袭，开发者应做的事情

"iOS8.1就已经有这个功能了，只是木有现在这么的火，现在的趋势是要火的节奏，因此很多电商平台B2B,P2P,C2C,X2X都有可能需要这个屌丝的付款功能了，在此简单的研究一下。"

第一步先修改target为iOS 8.1，当然支持中国的需要9.2以上且需要iPhone6以上了，然后在项目Capabilities里将Apple Pay设置为on，这将自动导入需要的库文件，然后添加一个权限文件并设置，最后修改或创建你的App ID。

正如上图提示的一样，你可能会注意到上面没有有效的Merchant ID，我们需要创建一个，访问苹果iOS 开发者中心的位于Identifiers > Merchant ID的页面。然后随着流程指引，创建一个Merchant ID并注册它。这个和其他证书差不多再此不做过多的阐述。下图是已经创建好的参考图片。

下载安装然后刷新下刚刚项目里面的界面，选择打勾即可，可以看到如下图

下面简单说下代码：

.h文件里面

#import <UIKit/UIKit.h>  #import <PassKit/PassKit.h>  @interface ViewController : UIViewController <PKPaymentAuthorizationViewControllerDelegate>  @end

.m文件

#import "ViewController.h"  @interface ViewController ()  @end  @implementation ViewController   - (void)viewDidLoad {     [super viewDidLoad];     UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];     btn.frame = CGRectMake(60, 100, 200, 50);     btn.center = self.view.center;     [btn setBackgroundImage:[UIImage imageNamed:@"ApplePayBTN_64pt__whiteLine_textLogo_"] forState:UIControlStateNormal];      [btn addTarget:self action:@selector(ApplePay) forControlEvents:UIControlEventTouchUpInside];     [self.view addSubview:btn];  }  #pragma mark ----支付状态 - (void)paymentAuthorizationViewController:(PKPaymentAuthorizationViewController *)controller didAuthorizePayment:(PKPayment *)payment completion:(void (^)(PKPaymentAuthorizationStatus status))completion {     NSLog(@"Payment was authorized: %@", payment);      BOOL asyncSuccessful = FALSE;     if(asyncSuccessful) {         completion(PKPaymentAuthorizationStatusSuccess);          // do something to let the user know the status          NSLog(@"支付成功");      } else {         completion(PKPaymentAuthorizationStatusFailure);          // do something to let the user know the status          NSLog(@"支付失败");       }  }  #pragma mark ----开始支付 - (void)ApplePay{     if([PKPaymentAuthorizationViewController canMakePayments]) {      NSLog(@"支持支付");      PKPaymentRequest *request = [[PKPaymentRequest alloc] init];      PKPaymentSummaryItem *widget1 = [PKPaymentSummaryItem summaryItemWithLabel:@"鸡蛋"     amount:[NSDecimalNumber decimalNumberWithString:@"0.99"]];      PKPaymentSummaryItem *widget2 = [PKPaymentSummaryItem summaryItemWithLabel:@"苹果"     amount:[NSDecimalNumber decimalNumberWithString:@"1.00"]];      PKPaymentSummaryItem *widget3 = [PKPaymentSummaryItem summaryItemWithLabel:@"2个苹果"     amount:[NSDecimalNumber decimalNumberWithString:@"2.00"]];      PKPaymentSummaryItem *widget4 = [PKPaymentSummaryItem summaryItemWithLabel:@"总金额" amount:[NSDecimalNumber decimalNumberWithString:@"3.99"] type:PKPaymentSummaryItemTypeFinal];      request.paymentSummaryItems = @[widget1, widget2, widget3, widget4];      request.countryCode = @"CN";     request.currencyCode = @"CHW";     //此属性限制支付卡，可以支付。PKPaymentNetworkChinaUnionPay支持中国的卡 9.2增加的     request.supportedNetworks = @[PKPaymentNetworkChinaUnionPay, PKPaymentNetworkMasterCard, PKPaymentNetworkVisa];     request.merchantIdentifier = @"merchant.com.example.lbapplepaydemo";     /*     PKMerchantCapabilityCredit NS_ENUM_AVAILABLE_IOS(9_0)   = 1UL << 2,   // 支持信用卡     PKMerchantCapabilityDebit  NS_ENUM_AVAILABLE_IOS(9_0)   = 1UL << 3    // 支持借记卡     */     request.merchantCapabilities = PKMerchantCapabilityCredit;     //增加邮箱及地址信息     request.requiredBillingAddressFields = PKAddressFieldEmail | PKAddressFieldPostalAddress;     PKPaymentAuthorizationViewController *paymentPane = [[PKPaymentAuthorizationViewController alloc] initWithPaymentRequest:request];     paymentPane.delegate = self;        if (!paymentPane) {            NSLog(@"出问题了");      }      [self presentViewController:paymentPane animated:YES completion:nil];       } else {         NSLog(@"该设备不支持支付");     }  }  #pragma mark ----支付完成 - (void)paymentAuthorizationViewControllerDidFinish:(PKPaymentAuthorizationViewController *)controller {      [controller dismissViewControllerAnimated:TRUE completion:nil]; }   @end
