Apple Pay开发详解

"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]（因识别问题，此处将尖括号改为方括号）#import [PassKit/PassKit.h]@interface ViewController : UIViewController @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 *)controllerdidAuthorizePayment:(PKPayment *)paymentcompletion:(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

在此过程中你可能会遇到如下问题：

1.countryCode 不知道怎么查，我这写的是中国的countryCode查询网站

2.currencyCode 不会查，到目前为止，我也没搞懂，在错误信息里面提示一堆，随便选的一个。

3.木有iPhone6手机，我就是其中之一…….

其他我认为比较重要的属性，请详细看Demo具体效果图如下：

上图皆为模拟器
